PC restarts randomly

[mentoslat]

My pc started restarting randomly a month ago. It restarts like 2-3 times a week , never twice a day. I get no bluescreen the pc just closes and start instantly, the fans don't even stop. I tried running gpu and cpu stress test but no result.I tried replugging all the gpu and mobo cables but still no results. I even tried shaking the pc and slamming the desk to make sure it wasn't caused by shocks. The restarts are very random sometimes when gaming , sometimes when watching youtube and sometimes just on desktop. I used a psu calculator to calculate how much my pc would need for 24/7 gaming and it averaged 50w under my psu. I even tried reinstalling the windows.

can you list down your specs? this sounds like a PSU problem. its very hard to get proof without proper equipment.
you can download HWinfo and check your voltages on your 12V if it outputs stable voltages +/- 0.3V.

Checked the voltages and they seem ok

sorry not during idle. during your benchmarks/gaming. just check what are your min and max values for your voltages. can you post a screenshot.

this is after 10 min on prime95 on maximum power consumption mode and furmark run simultaneously.

can you check your Event viewer logs if yo have any errors seconds before shutdown?
no overclocking? you only running at stock speeds with auto voltages?

All my speeds are stock , i did no overclocking. It restarted today and in event logger i got this "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."(ID:41). I'm guessing this was after it rebooted , before the time gap (i guess when it restarted) last error was this "The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{D63B10C5-BB46-4990-A94F-E40B9D520160}
and APPID

you should try to update your BIOS in case you havent. its got updates for your CPU/RAM. if you already ahve the latest.
shutdown everything. unplug your power cable. turn off PSU. press power button for 60 seconds. remove your RAM. remove your GPU. then put them all back together again and boot.

if that didnt work. clear your CMOS. this will clear whatever auto voltages BIOS has set. then go into BIOS make sure the defaults are what you want. like SATA mode and Booot modes are in the proper settings.
