I have a Dell Dimension 8300 with the original ATI Radeon 9800 Pro video card. Recently we have been experiencing problems with the display - a number of vertical lines/bars, about one inch wide appear on the screen. I've attempted to troubleshoot the problem by trying a different monitor on this PC (with the same problem resulting), and have also tried the monitor from the problem PC on a different Dell and it works fine - so I believe I have ruled out the monitor as the problem. Is there a way to run a diagnostics on the video card to see what the problem might be? And if so, how do I locate and read the results from the diagnostics, given my display problem which makes it very difficult to read the display? I was going to jump in and buy a PNY GeForce FX 5200 256MB card as a replacement, but thought I should verify the problem is the card before purchasing the card from Amazon, for about $30 (after rebate). Any thoughts on this card as a replacement / upgrade for this PC? Thanks in advance for any suggestions.
