I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP.
Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something.
I've been trying to remove and reinstall the correct drivers downloaded from Dell's website -> no solution.
I gave up and reinstalled XP - everything was working perfect again.
2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works)
Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition.
Today -> again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly...
As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install....
I'm out of options, can somebody help me to find a solution for this problem:
- Is there some way to backup and restore a bios after seeing some problems?
- Is there some way to know what is causing this problem like a bios diff utility?
