A few weeks ago my mom's radeon 9800 pro began sending a garbled image to the monitor. To confirm the video card as the problem I installed it in another old computer and the same problem popped up, and I also installed a geforce 3 ti200 in my mom's computer and it worked fine. I also tried another old card in her computer, a riva tnt2, and it did not work. I'd push the power button and the computer would start up, but then it would power down after only one second. I tried reseating, etc, but the same thing kept occurring. I figured the tnt2 must have been bad since the geforce 3 ti200 worked fine.
I just got a replacement card, a radeon 9600. I installed it and, you guessed it, the computer powers down after only one second. I tried the 9600 in the other computer and it boots up fine. WTF. I did a google search for the power down problem and found a lot of mentions of the power supply or motherboard. I don't understand why a bad psu or bad agp slot/mobo would prevent the computer from booting up if a riva tnt2 or radeon 9600 was installed, but it boots up fine with a geforce 3 ti200 or radeon 9800 pro installed(9800 is garbled, but it boots fine). That seems awfully random.
Before I take my own computer apart to swap in a new power supply, does anyone have any thoughts?
