I recently upgraded to a celeron 633 on my bx6r2 and it ran fine for awhile. I took the chip out to change fans and now I get no POST. the peripherals turn on but I get no video output or beeps or anything. I have already taken it apart once and I'll do it again as the night goes on. Anyone have any idea what my problem might be? I've tried two cpu's so most likely it isn't that. Cleared CMOS dozens of times with nothing. Tried everything I could think of, anyone got ideas?
