Ok I have done this in the past but I'm at a loss again. I either am having a brain fart or just getting too old and have Alzheimer's. So I get my son a 4600+ X2, take out the old 3700+ reboot the computer and all I get are beeps. No post nothing. I think I cleared the cmos. what the heck should I do.? I remember this happening when I went from a 3700+ to my X2 but cannot remember the fix.
