Hi, I have the same board as you and im pretty sure it does detect if it is too hot. If it is fried or w/e it could have been due to static when you assembled it, but that shouldnt happen if you are reasonably careful and ground yourself once and a while. Hmm, so you have tried reseating the CPU and the ram? Is the CPU from a new sealed box? maybe it is messed up from before you bought it. What kind of heatsink are you using? maybe it does not meet the TDP requirement of the processor. I use an 820 pentium D at 2.8ghz it's tdp is 95W if yours is faster it may be quite a bit higher and require a better heatsink.
