So you’re looking to buy a new PC but worried about what a CPU is or how much RAM you’ll need? Well I’m going to try and break it down for you into more friendly terms. I feel that a lot of high street stores try to squeeze every last penny out of people in order for their figures to look good

“…would you like an extended warranty with that sir…”

“…not really I live alone and the laptop will never leave the house, it’s simply a replacement for my current desktop that I’ve had for 4 years…”

“…but what if you were to spill a drink on it sir or to leave a pen on the keyboard and shut the lid…”

“…sigh, please let me just buy it and be on my way…”

We’ve all been there right? So what do you need to know when buying a PC? Well first of all I’d start by looking at the CPU (central processing unit) or processor for short. This is kind of the brain of the unit! The speed of this device is measured in gigahertz or GHz for short. The best way to determine if the processor will be fast or not is simple;  the higher the gigahertz the faster the ‘brain’ will function. A lot of processors out there have something called ‘Dual Core’, ‘Triple Core’ or even ‘Quad Core’.  This is easiest explained as the amount of processors inside the CPU and each ‘Core’ will have a gigahertz rating and again the higher the number the faster it will be.  Allow me to provide an example:    An Intel Pentium Dual Core processor, model number E2220, has 2 processors each with a 2.4GHz (2×2.4GHz) rating where as an E8400 model has 2 processors each with a 3.0GHz (2×3.0GHz) rating, so looking at the figures the E8400 model will be considerably quicker. Simple! Then just apply that to the 3 and 4 processor model. As a side note I think I should mention that a ‘Quad Core’ processor each with a core speed of 2.33GHz will be much quicker than the E8400 example as it has 4×2.33GHz processors – common sense I know, I just wanted to make sure you were still with me and didn’t have a nosebleed!  There’s no point in going for a superfast CPU if all you want to do is use the internet and use Microsoft Office. If you’re not doing anything that requires a lot of ‘umph’ so to speak, which is normally anything heavily graphics based like gaming or photo/video editing, then a low GHz processor will be just fine – use this general rule of thumb with all PC hardware. Applying this principle means you can now get good entry level laptops for £400 which would be more than adequate for general all round use. A smart shopper may even find something for the £300 mark – but just remember entry level laptops are exactly that and the higher the numbers the higher the price – but the faster it will go.

The next thing I would consider is the RAM (random-access memory). Take this to be the heart of the PC. There are quite a few different types of RAM on the market – some now more used than others.  The key thing about RAM is that it is measured in megabytes and gigabytes so again the higher the number the quicker it will be. We used to buy RAM in lots of different sizes but nowadays the most common form is 1 Gigabyte sticks so again the higher the gigabytes of memory the faster it will perform. You may see some computers displaying 512 megabytes of RAM; this is where it can get a little confusing – a ‘Gigabyte’ is more than a ‘Megabyte’ and without printing a list of exactly what the numbers refer to this is the simplest way to explain it.  I  don’t want you falling asleep now… A computer with 2 Gigabytes of memory is about average these days, 4 Gigabytes of memory will mean your computer will run nice and quick (as long as you’ve read about CPU’s). You can go above 4 Gigabytes but your PC may not be able to use it all, dependant on which Operating System you have but that’s a whole other conversation.

As I mentioned earlier if you’re not doing anything intense that’s all you need to know! The rest is just common sense – I mean you must know yourself what you’d like to use it for. If you’re into your photography maybe it should have a card reader but just make sure it will read the particular card that goes into your camera. Maybe you’d like the ability to plug your laptop into a flat panel (LCD) TV so make sure it has the correct connectors both on the TV and on the laptop – usually a VGA (video graphics array) or a HDMI (high definition multimedia interface).

If you’d like to know about other hardware devices i.e. graphics cards & sound cards etc there will be more overviews to follow.

So last time we spoke about Windows 7 I perhaps got a little too excited about how quickly it installs, can’t fully guarantee I won’t get excited whilst writing this either. What I plan to do now is put some snippets from the Microsoft website about new features in Windows 7 and give some advice on how they work in reality.

New ways to juggle windows

Overwhelmed by open windows? Windows 7 comes with three simple yet powerful new features called Aero Shake, Aero Peek, and Snap to help you instantly clear through desktop clutter.

“…Aero Shake – Ever need to cut through a cluttered desktop and quickly focus on a single window? Just click a pane and give your mouse a shake. Voila! Every open window except that one instantly disappears. Jiggle again—and your windows are back. (Who says the old mouse can’t learn a new trick?)…” So this is pretty cool right? Having a nice interface that doesn’t require you to have 30gig of RAM is always welcome.

“…Aero Peek – gives you the power of X-ray vision, so you can peer past all your open windows straight to the Windows 7 desktop. Simply point to the right edge of the taskbar —and watch open windows instantly turn transparent, revealing all your hidden icons and gadgets. Quickly reveal a buried window by pointing to its taskbar thumbnail. Now only that window shows on the desktop…” It’s not actually x-ray vision before you start jumping around. Although this isn’t available on the Starter version of Windows 7 it’s still a nice feature to have, gives the OS a ‘complete’ feeling – like it’s really been worked on this time instead of rushed out with a ridiculous price tag.

“…Snap is a quick (and fun) new way to resize open windows, simply by dragging them to the edges of your screen. Depending on where you drag a window, you can make it expand vertically, take up the entire screen, or appear side-by-side with another window. Snap makes reading, organizing, and comparing windows a…well, you get the picture…” Hhmmm after using Windows 7 for a while I didn’t really get on with this, sure it’s a cool feature and as I said before it does give the feeling of a good development team but the double click on the top of the window or simply ‘maximising’ is still king in my eyes.

Spectacular new wallpapers

“…We spend a lot of time staring at our PCs. Aesthetics shouldn’t just be an afterthought. That’s why Windows 7 includes a slew of new desktop backgrounds—wallpapers—that range from sublime to silly. Or try the new desktop slide show, which displays a rotating series of pictures (ours or yours). Your desktop will never be dull again. Windows 7 makes it easy to express your personality with creative new themes and other custom touches…” This, at first, seemed a little bizarre. Did Microsoft actually pay someone to go around the world taking nice pictures to put into their Operating System? And if so how do you apply for something like that!? However actually using this feature I was able to put some of my better holiday snaps on a rotation for my desktop and then in turn a friend of mine inserted a ‘fruity internet picture’ in said rotation – all fine until family came round to see my holiday snaps from Italy – bad times…

Retooled taskbar

“…Since Windows 95, the taskbar has served as the go-to spot for launching programs and switching windows. Times and PC habits have changed. So in Windows 7, the taskbar has been completely redesigned to help you work smarter, cut clutter, and get more done. Improvements to the new Windows 7 taskbar include thumbnail previews of WebPages, documents—even running video…” Ok, I’m gonna get REALLY excited here as this is my one of my favourite features about Windows 7. The new taskbar is fantastic in its simplicity, if you have multiple web pages open simply hover over the icon on the taskbar and it will display all the windows you have open in a smaller, thumbnail format just above the taskbar. You can then move your cursor up onto any of the pages, which will change super fast on the actual desktop, and then you just click on the one you’d like to view and Voilá! The same goes for multiple anything really, if you have Windows Media Player open it will show the movie playing in thumbnail, multiple folders open e.t.c.  Making it unbelievably easy to navigate all open items – gone are the days of having 70 instances of things open on the taskbar, having them all clumped up together and being unable to read any of them. Good work Microsoft fellas – not something you hear often.

Improved gadgets

“…Gadgets, the popular mini-programs introduced in Windows Vista, are now more flexible and fun. Based on your feedback, we’ve done away with the Sidebar, so you can stick your gadgets anywhere on the desktop. Favourite gadgets can go anywhere on your Windows 7 desktop…” Now I never really liked the sidebar in Windows Vista I think mainly because it slowed start-up so much, used so much RAM and realistically I don’t need a clock in the top right when the time is displayed on the taskbar. Sure there’s some good add ons for monitoring core temps and RAM usage e.t.c. With more and more people making add ons, or Gadgets as they’re more commonly known, hopefully they’ll be more and more useful ones.

With the Internet constantly being flooded by hundreds of new and more vicious viruses daily it’s never been a more important time to be well protected. It’s quite difficult to fully explain what a virus is as there are so many variations, we’ve know virus’ to be as timid as changing your desktop background to some rather unsavoury pictures to the more severe end of viruses which can launch on a particular date or time to transfer complete control of systems and networks to a single remote user, this could be to soak up all your internet speed or simply to steal important documents, log in details or secure site information such as bank details. These viruses are rare but they do happen, identity theft is becoming a very real problem.

So which Anti-Virus program should you choose? There are so many on the market and everyone has their own opinion as to their favourite. Well we’ve found a little known Anti-Virus package called NOD32, a nifty little package that will not constantly pop up asking you a hundred different questions about program access it also doesn’t slow your system to a crawl as some Anti-Virus packages can. It will occasionally pop up if there is something attempting to penetrate your PC but other than that it’s very much a stealthy program. Don’t take our word for it though you can try a 30 day free trial from here:  http://www.eset.com/products/nod32.php

Sadly no Anti-Virus package is 100 percent full proof, occasionally one may slip under the radar so to speak, so what next? If your Anti-Virus fails to remove or quarantine a virus the last thing you want is to have a rogue virus on your system doing heavens knows what so what we’re aiming to do is assist you in removing the tricky ones.

Again I feel that everyone has their own way of dealing with things but hopefully we’ll give you enough of an idea what you can do in this situation. Firstly you should fully update the Anti-Virus package you are using in the hope that the latest definitions file (the file that contains a catalogue of different virus names) contains removal details, do this until the Anti-Virus package your using reports that it is fully up to date then run a full scan. A full scan of your system can take quite a while so it’s best to do it at the end of the day or if you have to leave to office for a couple of hours. If the update still fails to remove the offending virus then more steps need to be taken, next I would find the “System Restore” option.

***CAUTION****

More and more PCs have built in destructive recovery programs where a small portion of the hard-drive is reserved for the operating system (2000, XP, Vista etc) and can be accessed via the start menu, PLEASE MAKE SURE YOU USE THE MICROSOFT WINDOWS SYSTEM RECOVERY AND NOT THE MANUFACTURER’S VERSION AS THIS CAN AND WILL FORMAT YOUR SYSTEM. When you’ve located this tick the box that reads ”Turn Off System Restore” as this is a well know place for viruses to attach themselves to. Now you should restart your PC and continually tap “F8” as the system is booting (this means start pressing “F8” as soon as the system starts to power on) if done correctly you will see a menu listing various different options, at the top of which is an option called “Safe Mode” this is a way of loading your operating system with absolutely nothing running in the background so don’t panic when it finally loads as it will look VERY basic. In “Safe Mode” most of the drivers will not be initialized. The next step is to re-run your Anti-Virus package because in this mode it may find the rogue virus that you cannot remove.

If the above steps still fail to remove the virus then there is one last thing to try, write down the name of the virus and then open your internet homepage, or whichever search engine you favour, and type in the name of the virus followed by “Removal Instructions” at this stage if it is a know virus there will be specific programs and or deletion steps advised to be taken, this may involve additional downloads or deletion of certain files in the registry. I cannot stress enough at this point if you are at this stage and you don’t feel confident poking around in the registry of your PC it’s time to give Rapid Web a call because if you delete the wrong items in the registry this could lead to loss of data or worse still it could cause your PC to stop working altogether.

So what if it’s not a virus it’s actually Spyware? Well you can follow the same steps as above the only real difference is the software you use to remove this, we can recommend 2 products for this, again personal choice but very effective, one of which is called Spybot: Search And Destroy – free version available here: http://www.safer-networking.org/en/spybotsd/index.html and the other is Adaware 2007 by Lavasoft which you can get from here: http://www.lavasoftusa.com/products/ad_aware_free.php again free version. As before just make sure both programs are up to date before using them as these can also take some time to complete.

Ok, so we’ve all heard that Microsoft are producing another operating system called Windows 7 but will it be any good? After their last lack lustre release of Windows Vista will people still put their hard earned cash into another Microsoft flight of fancy? Well after having used the release candidate version, that has been available for several months now free of charge, I can say YES! It’s everything Vista should have been! Over the next few weeks our techie supremos will break down the main features for you, perform comparisons to the current Windows XP favourite that the majority of us are still using and give some hints and tips to lesser known features from an end users point of view. Below is a little taster of things to come.

Let’s start with how it installs, after all this will be the first step for anyone, if you’re upgrading from Vista the install process can take a while as Windows 7 will change the settings and keep all the user information as is on your system but as with any new OS (operating System) it’s always advised to do a fresh install. I’ve been a techie for quite a number of years now and as with all techies anything that happens REALLY quickly gets us excited, I have quite a mid range PC just now (AMD X2 6000 processor, 4 gig RAM, 4800 series ATI graphics card) nothing particularly punchy, sure it’s not the slowest of PC’s but for the hardware that’s out there at the minute its mid range for sure. From putting the disc into the drive, allowing the CD drive as the first boot device and selecting the type of install I would like to perform it took 20 minutes, that’s right 20 MINUTES! I was astonished, sure it was missing a couple of drivers but only a couple, bearing in mind I installed this months ago when there was little to no drivers available an all round great result so already I’m impressed.

If anyone has used the help system in Windows XP or Vista you’ll know it’s pretty dilute however not so in Windows 7, it advised me that it had problems installing my Creative X-Fi sound card and would I like to use the online support, here we go I thought, a breadcrumb trail that leads nowhere… it proved me wrong! It advised me that I needed to download an additional driver from the creative site and put the web address on-screen for me, I thought ok, it’s better than the last help and support but I know where the homepage is, I clicked on the link anyway just to see where it would lead me. As I clicked the link a download dialog page appeared asking me where I would like to download the driver too, GENIUS! Although I’m not sure I should have got so excited about an enormous company like Microsoft finally getting their help and support system finally working after 2 OS’s and over 10 years of development.

What this does show us though is that Microsoft is finally listening to customers’ feedback about how users would like the software to work with the key responses being “…just make the features included work correctly and quickly…” – sadly something that Vista fell short on, very short.  So next time on the blog we’re going to go through some of the new features of Windows 7 and how they compare to Windows XP and the equivalent Vista features, stay tuned.

Here is our follow on article on the Look and Feel of Windows 7.

PCI refers to the Payment Card Industry.

PCI compliance, in this context, refers to complying with the PCI Data Security Standard.

Essentially, the PCI Data Security Standard is a worldwide security standard for information which was assembled by the PCI Security Standards Council. This standard requires a minimum level of security on servers and is designed to assist companies and organisation that deal with debit and/or credit card payments, in an attempt to reduce fraud.

PCI compliance applies to all entities which deal with information of card holders, either via the processing, holding or passing on of cardholder information. The PCI Data Security Standard (or DSS) requires the following of the network(s) and/or server(s) on which the cardholder information is sent through or stored.

• A firewall configuration must be installed and maintained to protect cardholder details.
• Default vendor access codes and passwords must not be used.
• Card holder data must be protected and encrypted when sent over open, public networks.
• Anti-virus software should be used and kept up to date on systems that are commonly vulnerable to malware.
• Developed systems and software should be  secure and ensure said security is maintained.
• Access to cardholder data should be restricted.
• All access to network resources and cardholder data should be tracked and monitored.
• Security systems and processes should be regularly tested.
• A policy that addresses information security should be maintained.

PCI compliance also reference wireless networks and their use, monitoring and security incident responses. Due to the inherent issues of transferring data wirelessly, PCI compliance requires at least quarterly security checks of any wireless networks in use and sets a minimum security standard for said wireless networks.
