I have a DFI NFII 400-AL ATX nForce2 Athlon Motherboard with a Athalon 2200 processor. I did not know much about swapping CPUs, so i did not install or look for updated BIOS. I swapped the 2200 with a Athlon XP3000 processor, witch is supported by my motherboard. When I powered it on, it ran for 1 sec and shutdown with no Beeping noises. Then it wont allow you to turn the PC back on until you pull the power plug for a few seconds and reinsert it. I gave up on the 3000XP CPU and reinserted the 2200 CPU. When I try to power on it will randomly shutdown on its own before windows boots up. I know it has something to do with the CPU swap I so foolishly tried, because the problem started right after i did the swap. Also I try to GET into CMOS settings to check things out, but the PC shuts down before I can take a look. Also there are 2 red lights visible on the motherboard if that helps. Also sometimes before it shuts down it goes through the LIST of processes and it does detect CPU temperature and detects the 2200 processor. I would like to still install the XP3000 processor but if I CANT I don't mind, I just want my PC back up and RUNNING again

The 2 most common reasons for this symptom are either the CPU heatsink/fan combo are not properly seated or it is shutting down from heat related warnings...did you remember to use thermal paste when you assembled this ? ?
Each time you swap out the CPU you need to carefully clean the paste from the CPU and heatsink and re-apply...
Visit Arctic Silvers website for excellent instructions on the procedure.

That'll save you from having to look around.

I have not applied any new thermal paste and the amount it had on it when i removed it was slim to none. I figured I could get away without using any just to see if Windows can at least boot to desktop before it over heats. From what I gather, the CPU does not seem to over heat within the few seconds it stays on. And the temperatures at start up show somewhere around 41C and 98F. But you guys know a heck of a lot more then me, so I suppose I will buy the thermal paste and hope it works again.
