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.
