Graphics driver reverts to 4-bit colour

[xPETEZx]

Hi Guys!

 

As If I hadnt already had enough trouble with my main rig, it seems that XP has decided to chip in to the problem pot.

 

As of yesterday, every time I shutdown my computer, and then later turn it back on again, windows claims the display driver is unsable, and reverts to 4-bit 640 x 480.

 

If I then re-install the drivers for my GTX285, it will install, restart, and all is well. If I then power down, and startup again, same problem occurs.

 

I have tried the following:

 

Tried the GTX285 in another computer, with 185.85 drivers, no problems, works perfectly.

Tried an 8600GT 256 in my main rig, shame problems occur.

Tried 185.85 & 182.08 drivers. Both display the same behaviour.

 

Both the GTX285 & the 8600GT work PERFECTLY in my second rig, with no problems whatsoever.

 

I have used Driver Sweeper to clear off ANY remains of drivers numberous times, and then cleanly re-installed a fresh download of 185.85 drivers from nVidia's site. To no avail. The problem still persits.

 

I have ran CCleaner and Spy bot S&D which both found no problems.

 

ANY ideas? I dont fancy re-installing my gfx rivers EVERY time I boot up!

 

Thanks!

I feared that response was coming.

 

And its not an option. I will not be re-installing a new OS till 7 RTM. Cant be bothered with all the tweaking and reconfiguring to get the OS to a state I am happy with.

Ok...

Does this problem occurs on another username? I had some problems with my card but only on my username...

It happens before I even log in.

 

The log in page is already in 4-bit.

 

If I select "update driver" and then point it to the location where the 185.85 drivers un-packed, it finds them and applies them, then restarts working fine.

Are the drivers starting when the computer starts up?

you can check the list of programs that start @startup in windows defender.

Keeping your computer on isn't an option?

 

Mine's been folding & gaming for 3 weeks straight.

 

But besides that, I don't know how to help.

[xPETEZx]

No driver does not start to begin with.

 

I then have to either reinstall it, within device manager, go to "update driver", then it works after a reboot.

 

If I stand by the computer, its fine, so I may just do that.

 

Still not ideal

Install Windows 7 RC so you get used to it before RTM

 

Otherwise, just put your computer to sleep instead, it doesn't draw much power

Have you tried any other drivers? or a windows repair?

[dr_bowtie]

un-install the drivers and re-boot....go in to your local drive and wipe the nvidia folder...(delete it)

 

if you have had an ATI card delete the ATI folder as well....re-boot and reload the latest Nvidia driver....

 

 

installing a new driver over and older one can create an issue when switching cards...

 

 

if the problem persist even after wiping the folder then I am afraid a repair is in order...although I wopuld recommend backing up your info and doing a full nuke & pave....

 

I know it takes alot of time but the time is general low compared to the time spent trying to fix an issue that wont go away easily....

[xPETEZx]

Hmmm, may just move to 7 RC 2.

 

Will see.

 

Tried all provided tips so far (bar the nuke & pave ) to no avail.

 

The strange thing is, this came completely out of noware. One day its working perfectly, the neXt its not. I didnt install anything, and no updates where applied. Really at a loss as to what cause all this.
