pc kept rebooting randomly

[mihawkeye40]

im going crazy i dont know how to fix this anymore it just kept rebooting whenever it wants to whenever im playing a game, whenever my pc is on idle, whenever im browsing it would go on for months or weeks without any reboots also this started happening when i first install windows 10 could it be a setting there that i need to turn off to stop this because its happening to my sister's pc too when i install windows 10 on her laptop.

 

things that i already did

-replaced my psu 

-replaced my motherboard 

-tried plugging it on a different socket

-tried using an avr 

-no standoffs shorting my motherboard out

-all cables on my motherboard are connected properly

-tested my ram sticks on memtest and memory diagnostics (no problems found)

-cpu and gpu not overheating (cpu temp under load : 69-71c sometimes spiking to 75c gpu temp on furmark 60-61c i dont know what my gpu temp is really at since my cpu is bottlenecking my gpu cant use my gpu at 100% usage)

 

i really dont know what to do anymore could it be because my cpu is bottlenecking my gpu no way right? please help

No.

 

What kind of outlet is you PC plugged into?  You should at least have a surge protected power strip with an indicator light for grounding.  It sounds like you might have inconsistent wall power and may benefit from using an uninterruptible power supply ( a small power storage unit between your PC and the wall to provide power when yours cut out for a moment.

@mihawkeye40, did you upgrade to Windows 10 or did you do fresh Windows 10 installation?

What version of Windows 10 did you install? (21H2? & prob. build number?)
