Hello everyone,

Could somebody comment, if my findings are right?

My computer keeps restarting while gaming. I thought it is a heat problem and installed a HW monitor and logging. Then I used Furmark. The temperature seems to be ok, both CPU as well as GPU (CPU around 50-55c, GPU 75-80c). But I keep some troubles with 3.3V going below 3.0V, just shortly before computer suddenly restarts.

Could this be the problem? (I can share the complete logging file)
Does a new PSU solve it?

Thanks!

Robert

Thank you for your answers.

I have a bequiet! PSU, 530W. I am running a system with Intel Core i7 960 (3.2GHz) and Geforce GTX 560 Ti. There is basically nothing else in the computer aside from 3 HDD. I am not overclocking or anything else. I hoped it will be enough to buy a 530W PSU...

So I guess I will buy a stronger one.

Regards, Robert

I have bought a new PSU. It is amazing: CPU and GPU temperature down by 5 to 10°C only by doing that. All voltages are much more stable. System is running perfectly!

Problem solved
