stuck in 640x480 and 4-bit color...Please help!


My Mother's computer is stuck with a resolution of 640x480 and 4-bit color.  I cannot change them.  This was working fine yesterday.

When I boot up the computer, all of the pre-windows screens look fine and then the actual Windows Xp splash screen looks totally normal.  But one's it enters Windows, it goes into that resolution and color setting.

I tried a system restore to a few days ago and that didn't work.  I looked in Device Manager and there are no bangs on any devices and the correct driver is there for the display adapter.  I downloaded the newest drivers anyways and installed them and it still didn't resolve the issue, even after a reboot.

I figured that this would be either a bad driver, video card going bad, or even the monitor going bad, but now I don't think this is the case.

Like I said, the Windows Xp splash screen is normal.  It has good color, it is totally fine.  So something is happening in Windows itself.

I thought for sure a system restore would fix it, but it didn't.

Is there any viruses or anything that can be causing this?  Thanks!

go into DEVICE MANAGER, locate the display adapter, expand choose the display component and review the driver tab.

ROLLBACK the driver. restart the machine and post back your results.

Hi irwinpks,

Thank you for posting.  I will try that.  I won't be able to until after 5pm tonight though.  Anything else that might cause this?  Thanks.

"Like I said, the Windows Xp splash screen is normal.  It has good color, it is totally fine.  So something is happening in Windows itself."
The splash screen etc. is using a generic VGA driver. It doesn't load drivers for your specific card until right before logon. So it still could be a driver or card problem. Most likely not a monitor problem.

What kind of video card is it? Also what motherboard/chipset?

One more thing...look in your boot.ini file and make sure ther /basevideo option is not present.

This is a Dell Dimension 2400.  The video card is a Intel 82845G/GL/GE/PE/GV Graphics Controller, that came with the computer.  Not sure what motherboard/chipset it is.  I'll look in the boot.ini to see if that is in there.  I did glance at it earlier, but didn't see anything that I thought would cause this issue.  Thanks.

I'll try restoring further back.  Thanks.

Try Dowloading the latest chipset drivers from dell and then the lastest video drivers.
mark-wa  do this please, eboot your mums pc tap f8 frequently then you will go to advanced options look down below safe mode and safemode  etc etc see start computer in VGA MODE click on this.
now once your huge desktop has re-appeared uninstall the display drivers from r/click my computer properties hardware device manager display uninstall.
then using your mainboard cd which you may not have oh well or the cp that came with your Laptop, go to control panel add new hardware choose the display adapter.
Or alternative is to boot to safemode logon to administrator press enter to bypass logon password, then go to system devices and uninstall the display adapter ok and reboot. windows should find your card and choose to install the correct drivers.

I ran into the same problem. On 4/17/2006 Microsoft pushed out a video driver update as part of "critical updates". Why a video driver is "critical" I don't know. The driver causes this problem.

Firstly, Dell doesn't seem to know anything about this. I spent quite bit of time on the phone, and they had no idea.

The solution I found was to do a system restore to a date before the update was applied. Then go to Windows Update and uncheck (hide) the video driver update so it won't get applied again.

Hi tgodfrey,

Do you know what the update was called?  Or what the kb # is?  Thanks!  I think you're right.  I think it's an update, but I think the Dell update software keeps reinstalling it.  I actually did a system restore further back and it worked, but then a day or 2 later it happened again.  So I had to restore even further back for some reason.  So I figured it might be some sort of update.  Please let me know if you know what one it is.  Thanks!

There was not a KB number, because I looked for it to find more information. It was just displayed as a video driver update for the 845 chipset. I don't recall the exact terms used, and I am no longer near the computer in question.  After you did a system restore, did you go to the Windows Update site and hide the update? If that doesn't solve it you might have to turn off automatic updates until this is resolved.
actually, just get into your device manager then click the + next to display adapter and then double click your video card.  once the properties are open, click the driver tab at the top and then click the roll back driver button.  this will install the previous drivers for your video card and restart your computer upon reboot, you may have to go back into settings and adjust your resolution and colors back, but you should be able to do this now.  I have done this for 3 clients, and my brother so far and it worked everytime
