Two days ago I replaced my AMD Athlon X2 processor for an AMD Phenom X4 precssor. Since that time I have problems with my pc: if I play a game, such as call of duty, a BSOD with the code: "IRQL_NOT_LESS_OR_EQUAL" turns on. One time the BSOD had the code "PAGE_FAULT_IN_NONPAGED_AREA". I already installed all the new available drivers. I attached my dumpfiles with this post. Could it be the Power supply? Could somebody please help me?
