Non-Responding monitor

[linuxconvert]

I have a newly assembled computer consiting of:

SiS mobo w/ 620 northbridge and 5595 southbridge
2 Celeron procs; 1 is S370 the other is Slot 1
64 MB PC100 RAM
Creative 52x CD-ROM drive
10 GB (?) HDD; I think its's Hitachi
BenQ V991 monitor

And when I turn on the computer, i can hear the fans whir, the CD drive light flashes, but the monitor reads "No Signal" and I know it's connected to the computer because if it's not, it reads "No Connection". and there aren't any tell-tale beeps.

I have tried everything I can think of. I checked for extra standoffs, checked the VGA pins on the mobo, made sure the speaker is plugged in, I even reduced the computer to the bare essentials (Ram, CPU, Heatsink, speaker) and checked for the POST screen. Nothing!
the lady i got from, even said it worked fine for her.
please help!

Take everything out/disconnect from mobo and power EVERYTHING>>>>

except
psu
cpu/fan
case speaker

Trip the power switch header pins with a screwdriver.

Any beeps?

If not, you know the problem is one or more of those things - mobo/cpu/psu

try a different monitor and graphics card

-if not, you just got ripped off

Not positive, but I think you can only use one of those cpu's at a time. Try taking one out, reset cmos and reboot .

well it was all free, so it's not like it's a big loss.

This might be kind of vague, but i tried changing a Floppy cable, and now all of a sudden the comouter won't boot at all! does anyone have any suggestions?

This mobo has socket 370 AND slot 1? Definately should only have one CPU in there. This is called a "no post" situation BTW....it has nothing to do with the monitor. First off, jumper the Clear CMOS pins on the mobo for 30 seconds, then put the jumper back into the "normal" position.

1) Lay the mobo out on a piece of card board or other non-conducting material.
2) Put in the CPU, RAM, monitor and video card ONLY. No drives nor PCI cards.
3) Connect the power supply and momentarily jumper the Power Switch header pins on the mobo.
4) The system should POST.

If not, try a different CPU, repeat. If not, try a different RAM module, repeat. If not, try a different video card. If all that fails, the mobo is BAD.
