For the past week I found out that my dad's desktop has been having frequent BSOD. I'm not exactly a computer whiz in BSOD so I'm not sure what to do.
It went BSOD sometimes even during startup.

I checked the minidumps and found out these problems:

Page_fault_in_nonpaged_area
Kernel_mode_exception_not_handled
IRQL_not_less_or_equal

these stops:
0x50
0x8e
0x0a

Can anybody help? I'm quite clueless on what to do, thanks.
