I have an old mother board that I bought for my son way back in 1998. It an Asus P4T on a 423 socket. It had a 2 GHz cpu. Its been running great and never had an issue.

Today when I turned it on, no video. Swapped video cards and still nothing. Reseated ram and still nothing. So I thought I would check the CPU and reset it. Did that and still nothing. Hum...Wonder if the CPU went belly up. I just happen to have a socket 1.8 CPU. Slap that in and bingo! Mother board is working again.

This rig has never been overclocked. It always ran at stock speed. Any idea what might cause a CPU to die? I'm asking because I never had one go bad until today.

Pretty rare for a CPU to die. However I have seen a LOT of RAM die lately.

Dunno. Check your radiation badge. Maybe your house was hit by a cosmic ray particle storm

Yup, only CPU I've ever had fail is one that I can say I killed myself (forgot to mount heatsink).

My guess would be ram or motherboard. I've never seen a processor fail (aside from breaking pins, doh!)

Same here. I owned a Pentium 4 Northwood 423 back in the day. It was the first computer I built for myself. The motherboard (an Epox - RIP) finally died but not after changing hands 3 times.

The board uses RDRAM. All the caps on the board still look great. Still baffled by the failure of the CPU. My backup CPU a 1.8GHz, works just fine, but if it dies in the process, then I guess there must be something wrong with the mother board.
