Computer restarting at random moments for no reason

[abidamaropol]

Hello everyone, so few weeks ago, my pc rebooted for no reason when i was gaming. Now it does 1-4 times per day, some days it just skips, and doesn't do that. It only does that, when im gaming, what could it be? Temperatures are normal everywhere.

These are notoriously difficult questions to answer...but what I would do first is re-seat everything. I have found that re-seating everything has solved this type of problem for me enough times where I find it worth mentioning.

You might want to run a few tests on:
- RAM ( You can run a RAM test from -> Control Panel -> System and Security > Administrative Tools > Windows Memory Diagnostic )
- GPU ( Make sure the GPU is not overheating, make sure it is fully connected to the PCI-E Bus )
- HDD/SSDs ( You can run HDD test by opening the Start Menu and typing, "cmd", right click and run as Administrator, then type, "chkdsk /f" )
- Check for malware/viruses ( There are various programs online to do this, I prefer to use Malwarebytes )

Make sure all of those tests have passed, if all pass just fine, it could be that your registry is messed up and you need a new install of the OS.

Gonna try this, thanks.

You have a quality PSU for that system? A reboot while gaming can be caused by the GPU (hardware of software) or a PSU that isn't good enough when the CPU and GPU are very busy. You stress tested both the CPU and the GPU?

My psu is not good, but why did it start only few weeks ago? I have this psu for very long time

Because it wears out over the years. We can't tell the PSU is marginal because you provided absolutely no info about your system components.

Gpu: geforce 740gt
Cpu: intel Pentium g3220
Ram: hyperx savage 2x4gb
Dont know other components atm, cause now im not home

You definitely don't need a powerful PSU for that hardware, but it has to be stable.

Thats the thing, but my psu is VERY old, didn't change it for like 3-4 years. I had Windows updates turned off since last year, and now i turned them off, maybe not updating system causes the problem

What PSU? Most of my PSUs are older than yours and my systems are stable. Not installing updates shouldn't cause restart issues; however I presume that security is not a concern for you.

You can't open the case to check which one is installed?

I did, but there is no info

You mean you have a PSU with no label at all? I've never seen that before.
