Random BSODs showing 0x124 (mostly), IRQL, 0x1E, 0x0A... hal.dll, ntoskrnl...
Occurs randomly and very frequently. Half of the time can't even load into desktop.
Prime95, when it runs, shows no errors, but half of the time when trying to RUN the workers, it (the program) crashes, WITHOUT giving a BSOD or a freeze etc.
In my 2 weeks of trying to debug this laptop there have been moments when it runs fine and I was able to play some games (notably) World of Tanks, Pirates of the Burning Seas, to test and ran beautifully.
Please help me solve this issue, I truly want to learn how to, thanks.
