Major issues - Please help!

[TheDean]

My rig has been brought to it's knees & I have no idea how or why?! Please help!

This all started with World In Conflict. I was running Vista x64, but changed back to Xp Pro due to poor performance. The game would often lock up or be unplayable even at the lower settings.
I now have seemingly much more serious issues.
Games will run fine for a while then start shuddering and 'jump'. When I alt-tab out of them and close them using Task Manager, the system continues to behave strangely - Eg I just tried to put Pandora on in the background while typing this and it just juddered like a stuck record!

Another issue I have encountered is when loading up games lots of red pixel lines appear on the screen coming from the right. They flash up constantly and this is very strange.

I am at my whits end as all was fine not long ago and I cleanly installed Xp less than a week ago

Please help!

Rig:
Xp Pro fully up to date
E6300 @ 3Ghz
2Gig Crucial Anni @ 5-4-4-8
BFG 320MB GTS
DS3 F12 bios

Anyone?

What power supply have you got, my uncle had simular problems, the place he bought it from suggested the ram was faulty they sent new ones, still crashing doing strange things, he phoned again and they sent a new motherboard, anyway before placing the motherboard I stuck my media center power supply in there and it worked without any problems.
If you have got a spare one might be worth a try.

Could be the card on the go? If your getting lines and pixels etc.

One thing you could try is a memtest or something, just to make sure your rams is fine and dandy...Although you would normally notice ram issues at boot up with display corruption or something.

What psu have you got as well out of interest? How old etc?

**EDIT**

Try as Rob suggested ^^^ If you have a spare psu try that.

I have a Corsair HX 620. Its less than 18month old and I tested it recently, so I don't think it's that.

I did however totally take off ANY overclock I had and it seems to be working fine now....What does that mean?

It could be throttling due to overheating, but it's unlikely. I take it you have ruled out any form of malware running in the background?

It's not stable when you overclock

Seriously though were you overclocking your cpu,ram and gfx?

If so I would apply the overclocks one at a time until you find the suspect.

There is another thread on here where the person had a totally stable system until they started running world in conflict and then unstable.

It seems that world in conflict is a very good stress test for overclocked systems

Well I did do a complete reinstall of Xp - So I doubt it's that.

Just CPU & RAM. I had the CPU @ 3Ghz and the temps were fine, so it must be the RAM. This is worrying cos it's crucial anni and awesome...I'll run non-OC'ed until crysis comes out then think about it!

Thanks for all the help...

To rule out the graphics card try running a CPU/Memory stress test such as Prime95 or Orthos. Run these for an hour or two to prove whether CPU/Ram is ok. If it fails you probably have a ram/cpu fault.

You can also try running one stick of ram at a time. Also make sure everything is set to stock and that all cards and equipment are seated correctly.

edit: I had a very unstable system a few months ago that kept on crashing for no reason. In the end I took it all apart and put it back together agoin and it has worked absolutely fine since. May be worth trying.

If your getting wired red lines/pixels the memory on the card could be faulty.
