generally you would update the motherboard drivers (but do not install the utilities)
and see if you still have a problem. if you do, i would run verifier
ie start cmd.exe or powershell.exe as an admin then run
verifier.exe /standard /all
and reboot.
it is best that you change the memory dump from a minidump to a kernel dump so that more debug info will be saved in c:\windows\memory.dmp file (just in case it finds a problem)
be sure you know how to get into safe mode so you can turn off verifier via
verifier.exe /reset
if your machine bugchecks during the boot up process.
(you have to turn off verifier after you are done testing and get a memory dump or your machine will run slowly until you turn it off) verifier check each driver for common programming mistakes. it calls a bugcheck on the first problem it finds.
generally, WHEA UNCORRECTABLE ERROR while gaming will be power or heat related problems. you have to look at the system up timer in the memory dump and see how long the system has been up.
if the timer indicates less than 15 seconds then most likely the motherboard logic detected a power problem and reset the cpu and it rebooted.
and the power supply let the cpu start too early. some cheap power supplies fake the signal to the motherboard that indicates the power is stable.
Rezhyn :
I fully wiped my PC and reinstalled Windows. I havent manually updated anything, should I use it for now and see if I blue screen again? Not sure if thats safe or not - or could I easily run the verifiers now in attempts of finding something?
