I recently picked up an older HP pavilion 762c running xp pro. It has a NVIDIA GeForce MX 420 Microsoft graphics card in it. I ran it connected to the tv for a few days and it worked fine. but now the display out put comes up with bars, and is very blurry. However when I run it in dual display mode, the second monitor it perfectly clear, but the first one is still broken up. I have tried running different display settings and everything I could find to figure it out. But no avail. Any suggestions. Remember I run on a very limited budget. I have checked the monitor and tv on other systems and they work fine. It has to be in the graphics card or in the settings.
