Booted to safe mode and everything worked fine - installed a new graphics card with it's drivers and system continued to boot to 640 x 480.
I reinstalled the old hard drive and the system works fine with 1024 x 768 screen but locks-up with the drive light on randomly during the day. Have run f-secure - nothing found. Ad-Aware - nothing major found. Spybot S&E - nothing major found. TrojanHunter - nothing found.
Installed new drive as slave and re-ran above tests with no malware found on any of my drives.
I reinstalled new drive as only drive and rebooted.
Used device manager to remove mouse driver and rebooted - system reinstalled mouse driver and now I have mouse back.
Downloaded and installed new graphics driver from Gateway - no change
Downloaded and installed even newer graphics driver from nVidia - no change
System works fine in safe mode and on old drive (with annoying lock-ups) but with new drive in place it will not let me change screen settings.
