I had my computer built several months ago and it has worked amazingly well until recently. It has started to randomly restart without warning. It does not freeze or turn off completely - just restarts. I get no blue screen nor error messages. I only get the black screen that tells me windows was not shut down properly and the option to start normally or in Safe Mode. If I tell it to run normally, it will boot up again just fine. Sometimes when it restarts though, it will loop. It will try and boot windows and fail and want to do a repair. I will allow it to do a repair and it will then boot windows once its finished. It has looped indefinitely before and I've had to reinstall windows. I reinstalled windows two days ago and its still restarting, but always manages to reboot or repair and reboot.
I have noticed it to restart when I play games (Star Wars: The Old Republic) and it has restarted twice when I alt tabbed and windowed the game to look up something online. However, it has also restarted on me while I was watching a DVD and while I was just surfing the internet without any other programs running.
I have run eventviewer and only found kernel-power error with bugcheckCodes as 0s. I have also run Memtest and my RAM seemed to pass. I've also noticed my speakers make a short static sound when I turn on my computer (like someone brushing over a mircophone). My sound also seems a little off sometimes when I play video games. We recently installed a new dvd drive Blu-ray/dvd burner. The sound issue is a bit more new and do not know if the two symptoms are from the same issue. I've checked my drivers but see no explanation marks and drivers seem to be up to date. This is driving me crazy as well as my much more tech-savvy friends. I will be running more tests, but until then.. help!!
Edit: I've also watched my temperatures and even while running the game, nothing went above 51 Celsius. It has restarted on me while looking for a solution online and nothing was higher than 41 Celsius! Sometimes it reboots after several hours of use, other times it will reboot after only being on for a few minutes.
