  1. A couple of weeks ago i was having trouble with random BSOD and managed to trace it to my power supply. I was running fine after i replaced it but starting about tuesday they started up again. Almost every time its DRIVER_IRQL_NOT_LESS_OR_EQUAL but its almost never the same file(i've seen NV4.mini.sys more than the rest but for the most part its ranged from USB.sys to win32k.sys).

    I've tried many diffrent things, I memtested the ram, tried swapping some out, checked my cmos battery, cleaned out the dust in my case, removed some of my PCI cards and reformatted but have not been able to figure the problem out so i attached 2 zip files with a few of the minidumps i have gotten( i have about 16) in hopes that someone can help me figure this out.

    Thanks in advance
