PC rebooting randomly without BSOD

I'd monitor your temperatures first to see if anything is spiking (CPU?) if so it may have an auto shut off.

Would be odd if it's a temperature cause, considering it sometimes happens after 5 minutes and then after 5 hours. On the other hand if your CPU is absolutely toast then it can easily overheat in 5 minutes.

I would consider just reinstalling your Windows cleanly, might be a nice way to reset a lot of problems. I do this every couple of months and it helps me keeping my PC up and running without any errors, unless hardware actually breaks. If reinstalling your OS doesn't fix it, it could well be your PSU or HDD.

Those are fine temperatures, how long has your PC been running?

Could be many things. My bet is on one of those things:
Virus, corrupted drivers or overheating/damaged hardware.

If you have a secondary HDD as a backup one or from a friend, try swaping them out. It could be dying out. Another possibility is a damaged RAM module, so trying a RAM test or doing a swap-around with missing modules could help you locate a possible issue here.



I would start by trying to reinstalling your drivers and redistributable files you have in your system. Doing a clean reinstall would be the best option. Then i would move on to doing a classic scan phase by your antivirus, TDSS killer, Spybot S&D, Anti-Malware and ComboFix (from bleepingcomputer).

If you reinstall your PC completely (format the HDD, SSD in your case) you won't have to sweep for a virus

Sweep for a virus if you want to keep this OS, do you scan frequently?

My important files, games, are on my second HD. Windows is installed on a SSD, so formatting isn't a problem.
I just need to find the ISO for windows.
I just finished MemTest86+, no error.

As soon as i get my ISo i reinstall windows

i've scanned over the thread, and i saw some mentions but no reply from your side (sorry if i missed). but did you update any drivers/windows/programs/etc. lately (specifically between you started having the problems and before).

cause imho, if that isn't the case i would totally focus on hardware. do indeed run a stress test and a memory test and scan your drives for errors, all preferably not from windows. otherwise rollback your changes (hoping you have windows rollback on, this is what that is made for) and check that first.

good luck.
