2nd card for 2 monitor setup. it is the second monitor not the default one. I've had this card installed since early 2005. I never had problems with it until a few months ago. now, for no apparent reason at all, it works just fine sometimes, then other times my PC loads without it, and when that happens it is undetectable on the computer. when it does work, it is only when the system is started up, not while it has been on for some time. PLEASE HELP!!! i tried a new driver but it doesn't make any difference. I looked on NVIDIA's website and they don't mention any bugs with the driver anywhere. I've heard others with GeForce cards have had the same or similar problems, but nobody has figured out how to fix it. They just suggest deleting the old driver and updating with a new one. Tried it. Doesn't make any difference. Any suggestions???
