Bought a new computer in May/08 and the blue screen crashes started in about a month. Yes its a NVidia driver GT 8500. I am running XP Pro, Clone system, Intel Quad Core Q6600, ASUS P5K-E WIFI Motherboard, 4GB of RAM, 500G HD, etc. with all the latest service pak updates. I have taken the computer back to the shop a zillion times now, they replaced the motherboard with latest ASUS, because some motherboards have an NVidia chip built in, and it was reported that they may be faulty, replaced the graphics card and its only Oct. I have uninstalled, re-installed several times while updating the driver.
When you go to the NVidia site you can read all about the bugs and fixes they have been working on, as they come out with updated drivers at a rate of 1-2 sometimes MORE a month. Theses bugs are for a whole series of drivers from the 5's to 9's. The only thing that stopped my crashes was to go and disable the driver but then you have no graphics, so that's useless unless you do not use graphics. Seems to me that NVidia has a major problem here and all should avoid them. My solution might be for me to return the whole system (still under warranty), and start from scratch. The last suggestion was to wipe and HD clean, re-install the XP Pro and all the software, now that's a fun job!
Interested in anyone that has a more recent video graphics card similar problem, since the forum seems to be dealing with older products.
