Specs: Windows 7, pentium 4 3,2ghz/2gb ram
So i recently changed my powerman 350W PSU to Corsair VX550W, so i could run my nVidia 7900 gtx graphics card. When trying to run Windows 7 it will randomly switch off. Which I am guessing is because of overheating. Since I have a quite old system I figured 550W should be enough, am I wrong?. I also discovered that my CPU a Pentium 4 3.2 ghz has a poor windows performance of 1.7. Again I have an old system, but surely it should perform better than this. Could it be this component that is overheating?

Ways to check might include starting in bios and watching temps if they report there. Also look there for temps shutdown and warn numbers. Compare them or enable them at least to warn.

Apps can also be installed to monitor temps on motherboard and maybe the video card.

Might look at event logs or dump logs. Watch for services that fail. Might go to services are change how they restart.

I'd consider running a live cd too to see if it might be software/driver related.

Might have a cold solder joint on the motherboard that is now found because of moving parts around.

Could try to reseat all components.

Why did it take me over a year to phone in a problem to ATT?

Thx for helping, really appreciate it.
I installed everest to monitor my cpu temperature and measured it to be 80 °C.
After that I changed the thermal paste and bought another fan to cool the system.
Now it runs on 50°C on stand by, is that hot?
On my Windows performance index it now states that the CPU is 4. I am not sure if that is low for a pentium 4 3,2 ghz CPU? Do you know if there is any program to test the CPU for damage?
