Windowx XP running only at 4 bit colour!!

I have a computer which kept crashing when loading up. We seem to have fixed this by adding an agp graphics card, bypassing the onboard graphics. This works and the computer has not crashed since. However, now the computer will only let me run it at 4 bit colour!!! I have tried updating the drivers of the graphics card, which is a matox 400 but it doesn't seem to work. The windows XP startup screen is shown properly but the 4bit colour happens as soon as the list of users appears. The graphics card has worked properly with winsows xp in another machine before so I don't think it should be a compatability issue between the two.

Does anyone have any ideas what could be causing this???

Thanks,
H

Now that I re-read your original message, that is the *exact* same video card that I've wrestled with!  Different system, I imagine (old Compaq ENS P-600), but the same video card.  We've only installed Win2K with those cards, (un)fortunately, but here's a link to the initial XP drivers for that card, if you'd like to give them a try...

Are you positive that you've installed the correct drivers?  I've (personally) had some real issues with Matrox drivers doing strange things *and* not always telling me when I've installed the wrong ones.

Anyhow, here's a link to the WHQL drivers for your card + XP....

I've had it running perfectly well with WinXP Pro (SP1 or original) but I fear it's this cheap PC Chips motherboard that's causing all the problems.

When you go to your DISPLAY PROPERTIES and click on the SETTINGS tab, are you able to adjust any of those settings or are they greyed out?  Underneath the picture of the monitor does it say something like "Plug & Play Monitor on Matrox G400"?  Can you adjust the resolution but *not* the color depth?  Can you not adjust either of them?

wjdashwoodAuthor Commented:
you could not alter the colour depth but I can't be sure about the resolution. Since I started this question I have now tried a completely different graphics card. With the new graphics card, then colour is back working, but the computer crashes.
I hope this helps.

The system is giving you a blue screen?  Just rebooting?  Freezing?

Do the MOBO & GFX capabilities match ?


AGP version 1.0...........1X, 2X ( running at 3.3v)
AGP version 2.0...........4X (1.5v)
AGP version 3.0...........8X (.8 or 1.5v)


AGP 1.0 does not mix with AGP 2.0 and 3.0

2.0 mix with 3.0

I can't find any info on the motherboard, it seems like an OEM PC Chips one. The Matrox G400 is AGP 2X I believe but I tried a GeForce MX400 and that should be AGP 4X.

We now have a new graphics card and it works fine, so it seems it was compatability
