Random restarts

[muindor]

My PC keeps randomly restarting, not too often, but just enough to be annoying. I can force it to restart any time if I run a CPU stress test (CPU-Z, Cinebench), but it also restarts under less CPU intensive situations like playing Overwatch (after long sessions generally). I checked thermals (my first thought), but CPU temps don't go above 85-90 decrees right before the restart. I'm running the latest BIOS and nothing is overclocked.

 

Any advice would be greatly appreciated!

I know you said your pc doesn't get too hot right before the random restart but what about a couple minutes before it. Do you ever get to hot at all? 

 

Also could be your power supply. Next thing would be my power supply. Might be faulty. You could use a temporary, backup or some power supply in general in replacement of your current one to see if that is the culprit and if the problem still persists it isn't your power supply. Typically I would do this with every pc component until I find what it is. Maybe checking the inside of that power supply and seeing if anything is fried would be good but I don't know why that would happen. That is a very good psu. 

Next I would also check my gpu, look if it's fried at all for any reason. And just for good measure use a mock gpu in replacement like your igpu and take off your current one and if the problem still persists it isn't your gpu. Basically I would just do this for all my major components until I find what the problem is. The problem about these random restart problems is that it could be anything. From what I know, usually its the GPU or PSU if your thermals are fine.

Thanks for the help!! I did some more digging and I think I found the culprit.

 

Some part of my system does not like my memory running at 3600mhz. I believe everything is supposed to support it, so who knows why it isn't, but when I turn off my memory profile, and manually set it to 3200mhz (with the same CAS latency and all as the memory profile), it seeeems to work fine.

 

Running at the lower speed doesn't really bother me. I just hope this solution works long term!
