Can any one answer me?

[IM back!]

could be you ram, if you have 2 dimms take one out and see if it stabilizes if it doesn't try the other. also try memtest86+ (look for on google).

another suspect would be the PSU but the only way or testing that would be replacing it.

and pleas post more system specs

Your system could be overheating. Try running it with the case open and see if the problem still occurs. You can also download a program like sensorsview or coretemp to determine how hot your components are running.

Of course, a bad psu is also very likely. The only way to check is to either take it to a computer shop and have the power supply tested (you can remove the power supply from the computer and bring just that) or to simply order a replacement psu.

Is this a prefab? That is, did you buy it already made? You might be able to get it repaired through the manufacturer.

Case open with a fan gently blowing on it. Just removing a side panel can create additional heat problems since the air flow channeled through the case would be disrupted... Heartborne is on the right track...overheating is a likely culprit...just add the external fan...

Also, have you checked the heatsink and fans for dust accumulation??

One other thought, would be to turn off auto restart incase there's an error message given...

Yes, you most likely will need a new/better power supply.
