Hi guys,

My PC is shutting down unexpectedly. Sometimes do not restart. Last two times tries to start again, but couple of times fails. Starts for a few seconds and stops again. Again and again after show me message that BIOS is corrupted and recovers it. After Windows starts normal.
I did these things – cleaned components, changed cooling paste on the CPU and scanned for viruses with Microsoft Security Essential. After went to the service and tested power supply. They told me everything is ok. Tested PC with Prime95 all night and nothing. Before three hours problem appeared again.
My Motherboard is GIGABYTE 990FXA-UD3,
CPU – AMD FX 4300 Quad Core
8GB RAM
GPU – NVIDIA GeForce GTX 650
Windows 7 Ultimate

Give me advice, please?

Thanks in advance!

Hi again,


I am writing again, because I do several things and the problem persists.
The problem - unexpected shut downs - were very often. The PC couldn't start - tried but just started for few seconds. When switched to other bios worked more, but after again switched off.
Replaced the power supply. No effect.
Tested with RAM, power supply, CPU and motherboard. Problem stayed.
Changed slots of RAM. Worked for a day, and the problem happened again.
Went to the seller. Bought a new mother board - the same. Worked all the time, but yesterday I saw end of the problem in the morning. Screen with warning that my hibernate.sys is corrupted. This is boot screen. Before it usually the PC shut fowns, after updated bios, trying to start, fails, tried to recover windows, again fails, and after shows that screen.
For two days - this is just one problem.
Everything is tested - memetes86 - no errors, prime 95 - nothing.
I didn't reinstall windows. Do you thing that could be a reason for the problem?
Or what else?

Thanks in advance and Happy New Year!
