computer will not boot up with processor in

I'am putting together a new comp. I bought a A7N8X motherboard, Athlon XP 2400 processor, Radeon 9100 128MB, ANTEC 350W power supply. I put it all together and it starts for about 3 sec. with no post screen and then shuts down. I first thought it was my motherboard being grounded some where. However, after taking the motherboard out of the case with just the porcessor and power supply attached it still had the same problem. I then tried another power supply and it still didn't work. I hooked my power supply up to another comp and it worked fine. I then pulled out the processor and low and behold it works. So, by process of elimination I think my processor may be bad. Are these the symptoms of a fried processor? Any input would be great. I have never put together a comp. from scratch so any input would be great.

I have also that problem a few weeks ago. Your processor is not properly inserted i think. Just pull the processor out and install it again. Check if it is properly inserted.

your crazy man. back when i was stupid i did the same thing and burned my finger, the cpu was dead to begin with.

my computer is so fast, it completes an endless loop in less than 4 seconds!

That's also an easy way to toast an AMD CPU on a mobo without AMD's COP built into it. luckily for this guy (if he followed your advice), his does.

I wouldn't recommend shutting off the CPU overheating protection. If his HSF was inserted incorrectly and that was what triggered the shutdown, then his CPU will burn.
