HELP!!!

That sounds like a voltage problem. What are your voltages - vcore, NB, SB, FSB, RAM, etc.? Core voltage (vcore) is probably the most relevant...
(Looking at your rig, 4GB of RAM can also be a problem for these boards, it seems, particularly if it's 4X1GB sticks. If that's your set-up, you might want to try raising your FSB with only 2 sticks (2 GB). You may be able to put the other two GBs of RAM back in later, by raising NB volts, but let's get your FSB/clock speed up first.)
