Graphics Drivers wont "stick"
I have just built up a system comprising
an Abit ZM6 board
Celeron 400 CPU
64 Mgs of PC-100 RAM
Creative TNT video card (AGP)
The system went well for about three days. It locked up and I turned it off. When I turned it back on I only had 16 colours available. I have tried every possible combination of uninstalling, deleting, reinstalling and updating drivers to no avail. I have upgraded to win98, reinstalled win98 on top of the old install, deleted win98 and reinstalled and finally reformated the hard drive. Regardless of what I do the problem remains the same with errors about hardware conflicts at startup and not being able to get more than 16 colours.
I have put my old 1 meg S3 PCI card back in. I can get 16 bit colour with this. This card
worked initially but I still get the odd hardware conflict message and get dropped into the hardware setup wizard along with a message along the lines of "The device is not present or not working properly or does not have all the drivers installed
(Code 24)" and again I have only 16 colours.
I can reinstall the PCI drivers but after a day or three I lose the drivers again and am back to 16 colours. The good news is at least I can reinstall the PCI drivers whereas the AGP/Creative TNT drivers just do not "Stick".
My only conclusion is that I have a an intermittent mother board problem. I can't think of anything that I can do to further pin down the problem. Can anyone confirm my diagnosis or point me in the right direction?
Windows does not use the correct video drivers because it improperly identifies your video card. This is because Windows can't see it. The usal cause is not having an IRQ assigned to the video card (all the newer cards require it). Check your BIOS setup and make sure Assign IRQ to VGA is enabled (it's disabled by default). Once you have the IRQ enabled, Windows will see the video card properly and load the correct drivers.
