Weird video problem - need help.

Hi there,

I wonder if anybody can help. My symptoms are that my monitor displays
goes black (as though the video signal has stopped) randomly for a few
seconds and then comes back. Occasionally it is long enough for the
monitor to go into standby mode so fairly certain the signal is ceasing.

I have tried different monitors (and video cables) same result,
different video card same result, stripped out the machine (RIMMS, Power
cables, cards etc.), cleaned and dusted etc. but still have the same
problem (although this last action seemed to cure it for a couple of
weeks - but now it's back!).

Bizarrely I can also get this problem when in the BIOS, along with
screen corruption so it's not a driver/software issue.

The problem does appear at random, this AM it occurred 45mins after
switch on but with no processes running as such so the machine wasn't
being hit hard. Also had large domestic fans blowing over the
motherboard to see if it was overheating but this make no difference
either!

I'd be really grateful for any opinions on this. Motherboard? PSU?
Running out of suspects! Not exactly a newbie here but this one has me
stumped!

At the stage I likely need to replace a component - but I don't know
which one - arrgghhhh!!! Really appreciate some help.

Spec: P4, 2.53Ghz/533FSB, 2x256Mb RDRAM, GeForce4 Ti4600, WinXP SP2 all
on an Intel D850EMV2 mobo.

Many thanks

Check your BIOS power settings. Maybe you've got a monitor timeout set.

Thanks for the reply. Unfortunately the BIOS settings are fine. The
problem, when it occurs, often manifests itself as the monitor going off
for a couple of seconds, back on for a second, then back off for a
second, back on, back off and then comes back on and settles down.

Ah. Well, that sounds like a bad monitor cable with a loose wire.

It does I'd agree. Except that I've swapped out the monitors and cables!

Well, in that case it sounds like gremlins. LOL

I can't think of any software that would do that but I suppose reinstalling
the driver would be a good idea just to take that off the table. Also
Windows power settings, which monitor Windows thinks it is, and settings in
any 'special' software the driver installed for the video card and/or monitor.

The next step would be to re-seat the video card, check the cooling fan, if
it has one, and, if none of that helps, swap in an alternate video card to
see if it's the card itself.

guess you checked all power supply cables, It could be a bad MB agp slot.
Well not actually the slot but the chip set controller. It could be a bad
power supply or one that is going south. good luck

I've got exactly the same problem on an Asus A7N8X ver 1.04 for one year and
a half. Never had a clue. Now I'm tired asking averywhere and reading
forums. The display goes blank for one second, no more, only once when it
occurs whatever I'm under DOS or Win98SE. I changed the PSU for a 475W
Enermax, I swapped the monitor, tried different cables on the two vid ports
and both monitor's one (BNC & VGA). Noway.
I decided to live with it.

This post won't bring help but it will show you're not alone in this dark
(for 1 sec ! ) world.

have you guys set a 'user' color setting in the monitors OSD?
