I just tried to upgrade my proc from a AMD 6400 dual to a 940 quad (blackbox). I'm running a Asus m2n deluxe mobo. Ausu say it will work but I'm not getting squat out of it. No beeps, no video, nothing.

Case fans are running, video fan is running....OK
Pulled proc to check pins - OK ( looked before I installed)
Video card pulled and reseated firmly.... OK
Reset CMOS...OK
Nothing else hooked up except HD, video card and memory.... NOTHING!!

No beeps, no video.

This is the second time I have taken down system and reset everything. Same results.

WHAT am I missing here??

Asus m2n deluxe
4gig OCZ PC26400
160GB WD HD
8800GT XFX

AMD 6400X2 dual core ( before installation of new proc) (it was running fine no problems at all ... maybe I should have left well enough alone!)

Thanks folks...
