Please move if this is the wrong place for this post.
I have a Socket 7 motherboard, the
Tekram P5M4-M+. The system has been running with no problems now for about two years. In it, I'm using one PC100 128MB module.
Just recently I switched out the memory module to test another that I had laying around. That module was a PC133 256MB stick. I've used PC133 modules on that board in the past and didn't have problems. After the PC133 module was installed and the system was powered on, the system starting beeping, like a beep every second or so (no video also). By the time I was able to power it off, it must have beeped like 15 or 20 times easily.
So after that happened, I put back my PC100 module and powered on the system. This is where it really gets interesting. Now with the original memory module back in, the system is still not booting. I get NO beeps and NO video from the system. I've tried to force the system to beep by removing the memory but still nothing. I've tried multiple video cards as well. The board has on-board video so right now I have no add-in cards on it. I've also tried removing the CMOS battery for a while but that didn't help either.
Any ideas or suggestions? Seems as if my BIOS was toasted, but I'm not sure.
