I have an 8300 that I use for Trading. I have 3 monitors attached. I have a ATI Radeon 9800 which came with the computer that supports 2 of the monitors. I installed a second Radion 9200 Pro card for the third monitor about a year or so ago. The displays and video have ran pretty much flawlessly for the past year.  A couple weeks ago, I started getting vertical lines and strange objects and artifacts in the 2 monitors that are attached to the Radion 9800 card. It is really bad at times and I can not see anything. Strange thing is, once I have the computer powered up and mess around with opening and closing programs, the displays will generally clear up, but they are still very poor quality. At first I thought I had a virus of some kind, but I do not. The third monitor on the Radeon 9200 card still works perfectly.

 

Has my video card gone bad? I have fooled around with some of the settings, but it does not help. I really depend on these for trading so any advice will be greatly appreciated.
