I took out 2 micron pc113 256 mb memory and replaced with 2-128 pc 100, nothing! I have a P3-850, nothing, tried a celeron 333, but i don't think the mobo supports it. The only card in is agp s3 savage 2000 video. I also tried to unplug the floppy, cd rom, and hard drive just to get into the bios, but nothing. The thing I don't understand is it will boot for about 5-10 seconds, not into bios, than it just shuts down.
