My old graphics card, an ATI Radeon x300 would generate an error code (Code 10) thinking it was a faulty card, I dealt with it. The only way I could use it was to manually uninstall and reinstall the driver after a reboot. I recently upgraded to an Nvidia Geforce 8400 gs. I chekced device manager to make sure it was correctly installed, but again I recieved the error message Code 10: This device cannot start. I checked the BIOS to make sure that the settings were properly configured, and as far as I could tell, nothing was wrong. When I start the computer, the card is recognized since a black screen displaying the cards specifications pops up for about 5 seconds, then windows boots normally. What is wrong here.
