Whoa whoa whoa.. get a copy of MEMTEST86 and test your new ram... Just to be sure... No need for reinstall of os...

He might have to. After many sudden reboots, the OS can have many corrupted system files and registry entries.

True, just saying that it could be the ram that's the root cause of all this crap. But an os should be only reloaded if it absolutely needs to be. (personal tweaks, etc are annoying to have to re-setup again and again needlessly)

Yeah my PC I found has been on and restarted itself in an endless cycle, I know the bios is set to do that when error occurs but either way, had to do so many forced shut downs from not being able to actually log on and tell PC to turn off, its probably screwed it up allot inside.

Download Hiren's Boot CD and test the memory with Memtest. XE

For the power supply, download your motherboard utility to monitor your voltages while gaming. Recently, with my new upgrade, I discovered that PSU is probably not good enough because of capacitors aging. It's almost 4 years after all and my computer runs 24/7. Use this PSU wattage calculator to find out if yours is good enough for your current components:

This.

Seconded!

At the moment Im using an Artic Power 700w PSU bought last month, but will try and use memtest now.

Short answer to your problem:
You're using a PC.

Long answer to your problem:
It's because you're running Windows 7 on a 5 year old computer. We all know Windows demands that you have a billion gigs of RAM and a 9GHz $7000 PC with all sorts of crazy parts to work.

Solution:
Try out a fresh Windows XP SP2 install, or if you're in the mood to upgrade, Apple just released a new line of Macbook Pros, all easily twice as powerful as last Year's models, with new LightPeak tech and i7 processors are standard. Lenovo's computers are also all really good, and can be Hackintoshed.

Tsk, tsk. Windows 7 works better than Vista. It works fine with 2GB of RAM and most games will be okay with 2GB of RAM.

Yes, the easiest of all solution would be to get a Mac, but it would be at a price. And let's not forget something, Garrus likes to play games. :P

The price of a (well-built) Mac is far less in the long run, in comparison to upgrading and fixing a PC made of cheap parts and virus cleaning.

Games? You do know that Mac has Steam now, right? Also, a good number of the games coming out anymore are for both Mac and PC. Spending thousands on a machine just to play games is stupid in my opinion, no matter what you get, but a Mac is going to be cheaper and far more reliable for far longer than any PC from any manufacturer (except maybe Lenovo or Dell, though their tech support leaves a lot to be desired).

I don't know about competitors desktop computers and their parts. I build my own PC. Okay, Apple seems to make a good offer in general for their computers in term of price, quality and performance, but custom build wise...

1- They don't offer any reasonable desktop gaming solution.

The iMac only has an HD5670 to offer.

You see the HD5770 down below? Well, the HD5670 performs 50% less than the HD5770.

If you want some reasonable gaming performance, you need to go to the Mac Pro... but it starts at $2500 and they only upgraded the video card for an HD5770. You don't even have a display for this price.

2- Their upgrade options are horribly overpriced.

Adding an HD5770 in the Mac Pro? $250! Last time I checked, this video card goes around $100-$125.

Yes, I'm aware of Steam offering more and more Mac compatible games, but the choice is still limited.

For work, if I ever need to have a laptop, I won't mind having a Mac. The Macbook Pro line has a nice design, they are robust and offer nice performances. For gaming, Apple still have good way to go. Perhaps when Steve Jobs will die that will change. I wonder if he was really sad when he hasn't received his knighthood title from the queen. XD;

Virus? Been months or perhaps years I havent got any. Just don't click any link you receive on MSN or in your mails and just don't use Internet Explorer. :X

I don't play games on computers anyway. It's a waste of money to just buy a multi-thousand dollar machine just to play a game that will work just as well on a PS3 or 360. I don't play games anymore on either of those either, as video gaming isn't fun anymore (long rant for another time).

Video cards are the biggest laughable waste of money of all. Buy a PS3 already! Who needs a $600 video card? Who even needs a $250 one?

Well, cheap parts aside, if you practice safe internetting and don't act a fool clicking on random-ass links on random sites, causing yourself infections, you'll do fine on a pc.

Heck i've used pcs for my whole life (pretty much) and the only times i've had to reload the os is because of something *I* messed up in the settings or whatnot myself, no virus involved. And most of my machines (at least for a while they were) secondhand machines.

I actually thought there was going to be something useful in this series of sentences.

I was wrong D:

A matter of your opinion.

I dunno about macs, not used to using them at all plus already invested some minor amounts of money into this machine just to modernise it.Windows 7 always worked fine on this machine though, it was only when I put the RAM in that it died, before that there was constant corrupted files in random stuff like game files one week and then it just became unbearable trying to run anything.

I hate to say it, it's probably the new RAM, the issues sound like the system is trying to store data in damaged modules and is unable to load it, resulting in 'missing files', the BSODs, etc. Very classic bad RAM symptoms.

Fortunately if they're new sticks the likelyhood of a simple Return-to-Manufacturer-Authorization (the much-fabled RMA) process is very high. Dead on arrival RAM is frighteningly common.

Maybe I've already got new terrabyte hard drive last night, new case too, just generally replacing everythng. There are pretty much the same problems with the previous RAM so I don't know if its the new RAM. The new one has the same bluescreening as the previous and still tells me page error on non paged area or something.

I hope it gets sorted soon, I'd offer advice but I am far from being a computer expert :P
