We have an older computer on the bench right now, that won't give us any video. We have tried a different ISA card, PCI Card, different processor, different memory and different memory. It is an older K%-100 Mhz using 72 pin EDO. If we pull out one of the SIMM's we will get the error beeps. The hard drive spins up and the power light comes up we just get no video. Any suggestions please.

Being the devils advocate have you tried a different monitor, make sure it is a multisync. Can you test the components on a different system. Just cause you get the error beeps when the simm is out doesn't mean it is a good simm. Do you have a prepost test board.

All things said It sounds like it is time to upgrade.

Good Luck Lee

We had a similar problem here. The fault, after a lot of component swapping, ended up being the memory. Make sure it is correct/compatable for your MB and that it is "totally" seated in place.

Assuming that all your components are compatible with your machine, here is a little trick that worked for me twice before. Try clearing your cmos via jumpers or removing the battery and turning the system back on for couple of seconds.Turn system back off, replace the battery and boot up. Hope this works for you.

This PC is hanging very early in the POST.
I would start at the beginning, and check the power good signal from the power supply to the motherboard.

When I walked into the old parts room, I saw our old Samsung MA2565 Mono monitor and its 8-bit mono/parallel card that we used for PCs that defaulted to the mono mode in boot up.
We have not run this test since 1996.
My first answer can not be correct. If an induced memory failure beeps, the PC has gotten beyond the video test to the memory test.
Is the display setting in the CMOS (Mono, CGA-40, CGA-80, EGA/VGA) set to Mono?
What is the default?
Why didn't an override or a mode change occur, and the video display anyway?
You have tried three video cards.
How far does this PC get in the POST?
Any sound from a floppy search? Hard drive LED/noise from HD reads?

Have you checked to make sure your video capture device is loaded? To check that you go to your control panel, click on multimedia, in multimedia, click on devices, in devices, click on video capture devices. If you are using a Windows based system, the Microsoft WDM video capture device should be listed. If it isn't, you can add it through add new hardware.
