The BIOS was set to 64 mgs for the video adapter and I moved it up to 128 mgs with no ill effects then moved it back to 64 mgs and no change took place.
A couple of days ago the user received an email from an old friend and she opened up the attachment which was a cookie receipt and all of a sudden the monitor when shimmering and you were not able to make anything out on the screen.
I took a look at it this morning and in safe mode the video display is fine but in normal mode the video display is as described above.
I did a restore from before the attachment and email was received with not success. I have removed the video drivers from the device manager in both normal and safe mode with no success. I removed the video card itself from the motherboard and put it back in the motherboard with no success.
I have finally disabled the video drivers from the device manager and now the operating system is working off of the default video drive from Microsoft. No new driver has been added to the device manager but the monitor is now working fine.
I am hoping that there is something that I missed in my diagnosis of the computer that will fix the drives for the video card.

hey, its a pity no-one answered you :)
it sound like you had a virus corrupt your video drivers
try using automatic updates from Microsoft website (not using express ) and see if there is an updated driver for you there
i sound that your card is working now with the Microsoft default drivers? , if so that is fine as well
if your card is not working your card could somehow got damaged
also go to manufactures web site and download a previous driver there
also make sure you did not set any new settings in the bios by accident refer to your notes if you made any
please let us know

I used trend micro to check for viruses and their web site found nothing. I uninstalled the two drivers for the video card and had the computer check for updated drivers but this did not seem to change the situation at all. Should I check for viruses again?

unfortunately if a virus had opened a door or has done what it was intended to do there is in many cases no way for you to detect it unless you spesialise in security :( the only way to get rid of that kind of virus is to reformat your machine and start fresh, but let us not jump the gun yet ,
you should start eliminating areas of problem to make sure what you know is what you know
1. replace the monitor with a well known working one and see if the new monitor does the same
2. test the cable by replacing it with a well known working one
3. test the card in a different computer and see if results are the same
4. reset your bios to default (after making exact notes on how settings was done in the first place)
5. replace your graphicks card with any pci card and restart your computer after computer has restarted replace the pci card with your original card

let us know
