Since you didn't provide a link or anything to the previous discussion, I'm going to ask something that may have already been covered. Are you sure the KVM switch is good? Have you tried plugging the monitor into either system directly to see if it works that way?
Posted the problem "NO signal to Monitor" on 2/10 and got a reply from Melati to try a few things with the video card - up to changing the card. I tried everything including changing the card and still nothing.
Here's all the system info:
Custom built Win98 sys
Pentium II processor
Trident 3D Images 975 AGP Video card.
Started having the problem of no signal and I would turn the system off and on until I got a signal. Problem got worse. Once there was a signal, within minutes the system started freezing up. Now I can't get a signal at all. I'm running two systems and one monitor with Belkin 2-port PS/2 KVM. Switched the cords and new system shows fine.
Need help fast. Have had the system for a long while and it has served me well.
Although it's a second system , I've got some very important stuff on it. Hoping it's something simple.
