Irql not less or equal after upgrading CPU

[daan]

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?

What are your computer specs? How big is your power supply? What version of Windows are you running?
