Guys, I need some help. I have the extreme version, bios F5C.

I just took out my 920 and put in a 940 and my PC turns on for 1 sec, then turns off and continues this loop.

I've tried resetting the cmos, I've removed the battery for about 30 seconds.

Does anyone know why this is happening and how I can fix it?

Do you think that maybe the CPU isn't seated correctly?
