Strange problems with turning comp off for a couple of hours

[seba79]

After turning off a comp for a long time (couple of hours) and then switching it on, Win XP does not recognize the drivers and makes the resolution 640/480. The reinsallation of drivers solve the problem, but when comp is again switched off for a longer time the problem repeats.
It happens only on 2 comp with various ECS mainboard and nVidia gfx. When comp is turned off for a shotrter time everything is ok.

Remove graphics card and clean the connectors then re-seat.

Is your system keeping the correct time?

MoBo Battery???

 

[dave holbon]

Suggest then looking at your AGP slot, could be a heat related problem (expansion and contraction) pushing the card upward. This was a problem with these slots about a year ago so now most have some sort of locking device at the rear of the slot. Is this connected correctly?

Battery is ok, card is clean, I don't suppose the problem is agp slot, because with Win Me/98 everything is Ok...

Then it can only be that the cards drivers are not being installed correctly. The machine can’t change its configuration whilst it’s switched off (normally). Chip-creep caused by heat can. So try all the chips on the mobo, BIOS etc, and the video card that can be removed to make sure they are all seated correctly.

I will try this, but I still do not understand why its happens only with Win XP....
Thanks very much for yours replies

I've also wonder if the reason somehow has a source in monitor (in both problematic comps are LG monitors, but various models)

Monitor Drivers, Compatability problem with XP???

Does the LG monitor(s) work correctly under 98/Me???

 

[dave holbon]

LG Flatscreen (CRT) perhaps?

I can't see any way the a monitor can influence your configuration unless!! it contains a virus. Have you done a virus scan?

Iv'e got an LG monitor, LG CD copier and CD rom. This still sounds like a heat related problem, at a stretch could be a virus triggerd to execute at a certain system temperature, but then it's in your BIOS. "DEEP S**T".

 

[seba79]

Isn't a virus.
Monitor drivers are standard winxp drivers...

I have to agree with Dave Holbon, I think the Video Card drivers are to blame.

I had an older Diamond Video Card installed in a Win 98se Box and the Video Drivers always gave me problems.

I always would have to uninstall them completely and reinstall them to make it work (more than once).

I was having the same problems with the Rez changing to 640/480 and that the Video Card was not configured correctly and so on.

Completely uninstall your Video Card (Drivers, Tweeking Software that came with it, everything), then install everything again. Maybe use the native XP drivers for the Vid Card instead of the ones that came with the Card and see what happens.

thank you, I've already solved the problem, by turning off agp x4 in bios...
