This old laptop is the perfect extra system to have around. Great screen, sound and keyboard/touchpad layout, blah blah ... but: It has a NVidia GeForce FX Go5600 graphics card. The history is like this: Got the laptop from my mother, too heavy for her worked great until the power socket burned out had it repaired the repair guy probably updated my drivers after that, the screen started showing blotches of kelly green wherever the screen was black, and on white backgrounds, there are pink-purple lines/areas/waves. I thought the screen was toasted because of something to do with the power, so I attached another monitor - worked fine! Definitely thought it was toast, but didn't give up I went to the HP support site and used their scanning tool. They have two drivers listed for my 5600 I downloaded and installed the newer of the two. Same problem Then I (on a fluke and out of desperation) downloaded and installed the older driver Voila!! Magic. It worked. Looks gorgeous. Now, the problem is that once in a while, every few days, the green and pink areas return. I roll back the driver and it's fine again! How can I delete the BAD drivers which XP is apparently accessing for automatic updates (or something like that)? How can I "lock" the good driver so that I dont have to roll back to it every few days? P.S. In my search for answers about the pink and green, I saw MANY posts in different forums with the same problem. Usually the answers tell the poster that the display is burned out, but now I'm not so sure and if it's just a driver issue, we need to let them know.
