I cannot get a video signal...

[beansbaxter]

Picked up a computer from a friend to work on it and I'm having a problem. When I plugged everything in, I was getting some bad POST up beeps. So experience told me it is either CPU, Video, or memory. I pulled all the memory sticks out, unplugged all the IDE, floppy, and PCI cards. I dropped in some memory sticks that I knew were good and it gave me back one beep - a good POST - but...

I am not getting any output on the monitor. The video card is integrated, so I dont know if it gets overiden by a PCI video card in the BIOS? I inserted in a good PCI video card, and still no video signal but I'm getting the one beep POST.

Any ideas on how to get the integrated video card or a PCI video card to work?

A lil info about the machine, from what I can gather looking inside...NEC computer, SIS 620 chipset, PC100 memory, dont know the CPU speed because the dang fan/heatsink is STUCK to it bad.

PLEASE HELP!!

Clearing the CMOS should help.

I cleared the CMOS and that didnt change anything...any other suggestions??

Not that it really matters, but the CPU is an Intel Celeron 433

Is your monitor plugged in and turned on?

Are you able to access your bios or boot into safe mode/

The screen on the monitor remains blank the entire time the computer turns on and POSTS up with one beep.

I cannot access the Bios or anything at all.
