This is a follow up to my recent question about a failing video card.
I had to replace my ATI video card after it failed. I currently have, on loan, an nVidia FX5200. I had a lot of trouble removing the ATI software and eventually followed a tip from the ATI site and used the MS Installer Clean up Utility. It seemed to work and I was able to install the card and load the latest driver.
On the first reboot an nVidia 'wizard' popped up and advised that the best resolution for my monitor was 1024x768 and 32bit colour. The new settings took effect and all was well.
A screensaver kicked it during that first session and when I closed the screensaver the resolution snapped back to 640x480 (still with 32bit colour) and would not be changed. A reboot did not change the situation. Device manager showed that all was well and that the card was operating normally with the driver I installed. Using 'Add/Remove' I uninstalled the driver, rebooted and reinstalled it again. I was able to get back to 1024x768 using nVidia Control Panel. All was well again but upon starting up the next day I was back again to 640x480. I could move the slider to change res ( as I could before) but although it told me it was changing to new settings, it didn't. I've tried everything I can think of since ..... driver in and out, safe mode, normal mode, using Driver Sweeper in safe mode ..... nothing works.
A couple of times while waiting for shut down I've had a blue screen pop up - IRQL NOT LESS OR EQUAL (I have a note of the tech info). I have seen this screen before but not often and not in the last few months. I am at the point of reinstalling Windows - can anybody help me fix this?
