Monitor Cutting Out

Ok, I'm mystified by this one. I have a client with an AOC 17" monitor on a P2 computer. The problem is, periodically the monitor will lose video (the power light stays green, it does not go into sleep mode). I've tried using a different monitor, as well as a different video card, and neither solved the problem. There is another system with identical configuration on site, and it has no problems, so I know it is not a hardware conflict. Usually when the video cuts out, it does it when they print from the workstation, and lasts for 15-20 minutes before the monitor comes back on. Any ideas what could be causing this?

When it goes out, does it do so all at once or a slow fade. Same for comming back on. Can you hear the flyback running (high pitched squeal - not everyone can hear it)? This woudl indicate loss of sync or somesuch. Is there any blooming?

Have you checked powersave mode in the BIOS?

Get a powerline polarity test gizzy. Check to see that you don't have a floating neutral or somesuch in the AC.

Is the SCREEN SAVER kicking in?

Ok, problem number 2, I haven't actually witnessed the problem, I just get a call from the client about once a week to tell me that whatever I tried last didn't work. I'll see if I can get some more information from them.

Hi wrussell,

maybe it's a problem with powersave anyway. Sometimes the connector on your board is open and gets loaded. Try to isolate and check your BIOS.

Hope that helps

No, power save mode has been completely disabled in the BIOS. I'll try your suggestion of reloading the printer driver next time I'm out there.

The problem is from the ATX case and the motherboard...What kind of case are you using and brand Motherboard?
Epox has a fix for this problem with thier boards and certain cases on thier web site.

It is a TekRam P6L40 Motherboard, and an Inwin Mid-Tower ATX case. I could not find anything having to do with this issue on TekRam's support database.

I think the enrgy saving in Win95 overrides the bios settings. Try a right click on the desktop (control panel -> display -> screen saver) and see if the monitor shutoff is enabled.

Well, after much searching I think I've found an answer. According to TekRam, the motherboard is faulty. I'll let you know if that solves my problem just in case y'all are curious.

Check for an IRQ conflict on the video card.Probably with the NIC.

Try to change your video card. I think the problem will be there.

If you read the question history, you will find in one of my comments that I have already solved the problem, some time ago.

I know, you solved it,
but did you look in the BIOS for diabling IRQ for VGA ?
I found that it helps many times.

Try the working computer's video card on the faulty computer. Does the monitor have a problem with the computer that works?
