About a month ago I setup dual monitors on my Windows Vista PC. I had an extra monitor lying around and my video card supported two DVI devices, so I figured it would be worth it to utilize the extra screen space. Unfortunately, it became the cause of major problems and forced my hand to switch to my Macbook full-time.
Once I setup the dual monitors, the screen would flicker on and off for a few seconds about 3x a week. It would either recover and give me a little message saying “Atikmdag has stopped responding and has successfully recovered”, or it would crash completely and go to the blue screen of death. It was annoying, yes, but I dealt with it as I searched for a solution to rid myself of this issue.
