I recently got myself an MSI ATI Radeon X800XT which to begin with was extremely unstable even with the latest ATI drivers (the MSI drivers were useless and performed really badly). The solution to this was simple all I needed to do was completely remove the drivers via uninstall and reinstall them...first time I have ever needed to do this, but hey it worked! Not long after my PC wouldn't start up intermittently, all power would come on, but it would just hang with the monitor not even kicking in. Eventually it would kick in after I turned it on and off a few times. So today I get home from work turn on the PC, same thing happens, but this time it doesn't correct itself. I take out the card and replace it with a trusty GeForce 5600 which is a good few years old, and it starts up fine. One thing I did notice is next to the AGP slot there is a red light which flickers when I insert a card. It does this for the 5600, but not for the X800 so I'm assuming somewhere something has probably blown in the card and the mobo no longer detects it's there. The X800XT also requires extra power from the PSU so there is a possibility it's not powerful enough I suppose, but it obviously gets power since the fan starts up when I turn the PC on. Basically I'm just asking for clarification from people in the know that it is the graphics card that's faulty. My system specs are: PSU: 450W Mobo: Asus A7N8X2.0 AMD Athlon 2500XP 1GB PC3200 400MHz (running at 333mhz since CPU is 333mhz, I have every intention of upgrading at some point, but it's never caused a problem) 2 x 80GB Hard Drive 1 x DVD ROM 1 x DVD ReWriter MSI ATI RADEON X800XT (currently Geforce 5600) Is this too much load for my PSU? I never have overheating problems, just to rule that out. Thanks for any help.
