The PC went off this morning, then on, but only for 5 seconds. I couldn't turn it on again so I removed the power cord, and after 5 minutes I tried the power button again: the system started up, went into Windows, but after 5 minutes it shutted down again. I could only restart it after, again, i removed the power cord from the PSU and let it rest for a bit. Once started I checked BIOS to for temperatures and voltage, everything was ok but after a couple of minutes it shutted down again.
The only thing i changed in BIOS, is the memory settings. They were automatically set to 1300. I loaded the XMP profile and set the speed to 1600.
It is worth mentioning that when I was in Windows, the system didn't suddenly go off (like a power cut) but more like a force shutdown from windows. It's because of this i have doubts it is the PSU to blame... or maybe it is. Everything was running smoothly with no problems until this morning
PS : when the PC shutted down the first time, there was no power outage.
LE : i rebooted my sys and checked the eventlog in Windows ... i am a bit stunned
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
