Systems Keeps Reebooting

[confuseis]

Hi All

My Machine keeps reebooting! Nothing has changed recently as this machine is not used much.

There is no blue screen the system just restarts with out warning.

I have checked the c:\windows\minidump for dump files but there is nothing there

I have ran sfc /scannow for windows errors chkdsk /f for hard drive errors.

I have made sure windows has all updates.

CPU Temperature at 52 Celcius

I have run a hardware diagnostoic and all the hardware passes.

The Power supply is a high end one and rated for well Wattages wellabove what is needed on the machine 1000W.

Not sure what to do next. Any suggestions

Thanks

Even a "high end" PSU is not bulletproof. In nearly all cases where the symptoms were the same as you've described, I fixed it with a new PSU (I fix computers for friends in my spare time).

However, in a couple of other cases where those same symptoms occurred it turned out to be a faulty motherboard.
