Problem of restarting PC exists

[muhibulhaque]

Hello my dear,

Thanks for paying consideration on my request.

Now I purchased a new branded PSU of 460W (brand name: COOL MASTER), this time I am using Vista 32 bits instead of 64 bit (because I have 2gb of ddr2 {1gb x 2} on the same PC.

I installed various 3d games (like Need for speed Undercover), but the PC restarts after 15-20 minutes of playing games. (Problem still exists).

Please help me because this time I am out of my budget (I have already replace my old PC with new one).

A common cause of this type of problem is overheating.
Download and use GPU-Z and see what the graphics card temperatures are.
Download Speedfan and use it to see what the CPU temperatures are.
Check both temperatures at idle and under load and let us know the results.
