Random Reboots. No Errors, No BSOD, instant shutdown. - Win7 64

post #1 of 5
Thread Starter 
I'm not sure where to post this, as I currently have no idea whether this is a hardware or windows problem but here it goes.

In the last two days my PC has randomly decided to instantly shut down and reboot, so far this has happened 3 times. I receive no warning, no errors, no BSOD, No hangs, no freezes nothing.
It just suddenly appears to lose power and then reboots, I also can't really find anything in the logs, except that windows noticed that the system shut down unexpectedly.
No new software has been installed, no new drivers, no settings have been changed, no updates. Everything is the same as it was last week.
The problems does not seem to occur when the system is under stress, my system has been overclocked for quite a while without issue, and during gaming it's fine. So far it has only happened while I was using Firefox, with just one or two tabs open.

I have no idea how to begin to diagnose such a problem.
Would anyone care to give me some tips?

I dont think its an issue with your psu, its a good unit with much more juice you need to cover your pc power supply. So my guess is an unstable overclock. Try to reset your bios settings to stock cpu speed/vcore and check if you gain any stability.

I agree. The Antec is a good units with plenty of power and usually if the PSU overloads/heats you wont be able to turn the comp back on for a few minutes. It could be a short circuit, check for damaged/melted cables connectors. It could also be a mobo issue though thous usually result in a BSOD and not a hard reset. You could try and run the system on just one RAM stick and see if that makes a difference. Also dropping back to stock and see if that has an effect is advisable.

Thanks for the replies. I'll turn it down to stock for a few days and see what happens.

Are you sure you aren't getting a BSOD? I've seen them go really fast and i didn't even notice it until i looked in the crash logs. Your Motherboard could not be grounded properly, ( stand off improperly placed or even a screw or something in between the tray and MB)
