Subject: inconsistent graphics card problems
Question
Hi, I recently aquired a new graphics card, while installing it in windows, the system froze. restarting took me as far as the windows loading screen then it froze. further restarts took me as far as the motherboard splashscreen, and then to simply a black screen. i've stripped out all other components and left only the gfx card in. i have no onboard graphics so there can be no conflict there. perhaps the strangest symptom is this: if i leave the system running (with a black screen) after about 15 minutes it starts up and i see the POST screens. i can get into setup this way and have checked the PSU is working properly. the inconsistency of the problem is the most frustrating.
any ideas?
it's a 8600GT.
the gfx card it replaced is acting in exactly the same way when i put it back in.
thanks for reading,
Jonathan
Answer
Sound like a driver problem.
You'll want to put the old card in. Before windows boot keep hitting F8. Choose safe mode.
Once in safe mode, go to device manager and expand video adapters. Right click any cards listed and choose remove/uninstall.
then go to add/remove programs. Uninstall any software or drivers for either card.
Shutdown and put the new card in. Enter the bios and choose to load the setup default and save.
Reboot to windows. Cancel the device wizard. Go to Nvidia's website and down load the newest drivers for the new card. Install them and reboot.
If the problem persists, check the wattage of your power supply. Make sure you have plenty of power to support the new card. Your gonna want at the very least 450 watts. More is better.
