Windows 7: Random BSODs on old system, frequent & started only recently.

03 Mar 2015   #1

Windows 7 Ultimate x86
Various BSOD

A old ( 2007-ish ) system of mine has been getting frequent BSODs since a couple of weeks. The BSOD messages are mostly different each time and include "IRQL NOT LESS OR EQUAL", "PFN LIST CORRUPT" and "BAD POOL CALLED". Sometimes it will take a day or so before a BSOD appears, but after a reboot it usually doesn't take much time before the next one appears. I'm suspecting the PSU but perhaps it's the motherboard or something else entirely?
