Thanx to all for the help.I took out everything, and replaced one at a time, and still the same problem, so my problem is with my mobo. I'm getting up the nerve to flash my BIOS, and hopefully that will solve the problem. Also I noticed in my device manager my system recognizes 2 memory controllers, and says 1 has a problem. If I delete that one, when I reboot Windows re-detects it, and comes up with the same problem. So as I stated earlier I am going to try and flash my BIOS. Hopefully the next time you hear from me I'll have good news in this forum, or I'll be in the bargain basement looking for a new board.
