just to clear things up a bit. before taking the comp for repairs, my specs were similar, just i had a different motherboard and a ATI x1950 Pro ICQ3 AGP. after taking it in for a checkup, the people find out that the problem was the mother board heating up. they replaced the motherboard with a new one. in doing so, i required a new CPU, DDR-2 RAM and had to get the 512mb ati x1950 gt which is PCI express. for a while, the issue of random shutting down wasnt there, but i did have my suspicions of the power supply being an issue, because the comp did shut down on 3 occasions while playing a game that required a lot of cpu and gfx. i'd like to thank you for ur reply. I'm pretty sure i have the latest drivers for my gfx card. but anyways more to the point, do you believe that the power supply could be the only issue? as i am planning to reformat my comp because of some issues with spyware/adware/viruses etc.

I forgot to add my graphics card that is a 512mb ati x1950 gt

Thanks for a reply My specs Dual Core e6420 2.13ghz (2x2.13ghz) 2gb ddr2 ram 160gb hard rive motherboard- asus p5l 1394 power supply 400 watts I have done that before but the problem is that the computer just shuts down randomly and doesn't reboot at all, when playing games (stalker) and (command and conquer3) so I have to pull the plug out and plug it in and wait for a minute then it will start again, but if Iam using the internet or using word, etc its ok and will not shutdown at all.

Please HELP I have recently change my motherboard, cpu and ram, and having this continuous problem with my pc. When playing games my computer shutdown randomly I took it to a technician and they just replaced everything besides the powersupply and they said that the power supply is not the problem. How do I know its the power supply I doubt it is the motherboard or the cpu heating up. Here are the voltagesCase -|2.42 V|3.63 V |3.18 V |5.35 V |12.40 V| -10.88 V| -4.80 V
