Why is my computer restarting?

So for the past week my computer just randomly restarts for no reason. Only when Im playing WoW, another game, or watching video. All my drivers are updated, Windows is up to date and the computer is less than 1 year old, what am I missing gang? HALP!

EDIT!!! ALSO I get logged out of websites I have been logged into about every 3 days. That used to never happen and I changed nothing =(

this question is probably better directed in the technical support section. you will likely get a lot more help.

posted there as well! TY!

If you’re overclocked your system is unstable. Reset back to factory defaults. Also try cleaning up some dust. Make sure all connections are properly connected. Check temps of cpu and gpu. Download hwmonitor or any other program you prefer to use.

I had an issue some years back buying a PC from Cyberpower where the Motherboard was my issue, it would freeze up then force a restart. Sometimes it wouldn’t detect the RAM or the M.2 SSD slots and needed to be restarted often, many times it would go straight into the BIOS menu on startup failing to detect the boot drive. I tried to update the BIOS, which I’ve done times before, and it black screen indefinitely after that. Fun times!

I would guess that the constant signing out is due to corruption of browser cookies that’s occurring as a result of the ungraceful restarts. Actually someone in my social circle recently lost all their browser data that way.

As for why it’s restarting, that’s really hard to tell. If you have everything backed up I would try making a fresh Windows installer thumb drive as detailed on Microsoft’s site and doing a wipe and clean reinstall of Windows. If restarts persist through that you’ve probably got a hardware problem of some kind.

I would start here.

When a computer randomly restarts, I always look for heat first.

What do you mean by restarts: just dies and powers back up or does a regular restart as though you’d initiated it?

For the first, if you’re getting BSODs look up the code its throwing. Otherwise, my top guesses are a power or heating issue.

Have you checked for a virus? Do you have an anti virus installed? You can go freebee anti virus for basic coverage or you can pay to get something more advanced.

check system temperatures, power supply rating vs power demand of installed components, disable overclocks.

is this pc prebuilt aka from walmart or something or custom
i might check the paste if its a prebuild sometimes they would not add the right amount of paste

Maybe bad ram, or over heating
