Hey Everybody.
Been Having some bad Bsod on a new 3 days old pc.
I Sometimes get ntkornel.sys, dxdiag,ntfs.
After formating and reinstalling windows I got win32k.sys.
After reinstalling the windows i've decieded to put my PC in a lab they've had it now for 4 days(Im writing from my laptop) and they ran the following test:
-Memtest 86 for 23 hours(no errors)
-CPU stress program(cant remember the name) no errors/crashes
-Furmark for 10 hours (no crashes no errors)
he still didnt connect the computer to the internet
now he is saying it didnt crash at all so my question is can it be an external connection in my home?
if so what? keyboard,mouse,lan,screen usb,speakers,dvi,power.
Please help ty.
