So I have this clients PC that blue screens and gives a IRQL_NOT_LESS_OR_EQUAL STOP 0x0000000A error message. Error Goblin (link in sig) says the following: And I have NO IDEA what the hell that means. It has wrapped around my head 5 times and caused it to explode. Ive ran memtest for 7 and a half hours and it didnt find any errors. I will probably run it again overnight just to be safe. Ive also cleaned out the computer with an air compressor and checked the hard drive for bad sectors are none are to be found. Im trying like hell to avoid reinstalling Windows but it seems unlikely. Im going to try updating some drivers and see what happens. Some of the drivers on this computer date back to 2007. Suggestions are greatly appreciated. Thanks guys. EDIT: Alright so it doesnt look like ill be able to get onto the internet to do anything because nearly every time i try, i get the BSOD. Format seems imminent.
