Since a few days ago, my computer has been rebooting out of nothing. It started when I was working behind Microsoft Office Word 2010, doing a project. When it reboots, it's like someone pulls the plug out of the system, it completely shuts down, and afterwards it boots again out of itself. This is not the same as a normal reboot, and the PC doesn't display a BSOD either.
When it reboots, it's unable to boot up Windows 7 again. I've tried start-up repair, but it cannot fix the problems or repair the system. I tried wiping my partition and reformatting. At first, everything seemed okay. I left it in idle for about 24 hours to rule out if this also occurs when in idle, uptime was still counting and nothing out of the ordinary happened. However, when I started configuring the clean OS afterwards, it suddenly out of nothing did it again, and no, I couldn't boot Windows 7 anymore, it shut down and powered up again.
When I configured the PC, I've installed no external software, except default configuration like UAC, Computer Management, Users & Groups, etc. - To exclude the possibility of external corrupted software.
I tried the following, without any kind of success:
- Scanned the entire system completely
- Booting with no peripherals
- Booting with only the necessary needed (motherboard, RAM, processor, etc.)
- Booting from safe mode
- Trying startup repair
- Formatting the PC
- Wiping the partitions
- Windows Update
- Windows Repair (from install DVD)
- PC also doesn't overheat
