PCI Express x16 graphic card installation problem
Posted on 2010-11-08
My computer is running on a Intel D945GTP motherboard with on-board video. I recently purchased a Radeon 512MB graphics adapter (PCI Express x16). This card does not require an additional power connection. My computer has a 350W Power Supply and is running Windows XP SP3, and has 1GB of memmory, and a 80GB HDD.
I have changed BIOS settings to PCI-E, saved and exited. I then went into windows device manager and disabled the onboard video adapter. Turned the machine off, plugged the monitor into the new graphics adapter, restarted the computer. The computer posted, windows screen appeared, and then the desktop...everything appeared normal for about 15 seconds, then suddenly the computer screen went black, but kept flickering. The computer did not shut down, only the graphics with the intermittent flickering. I rebooted, but experienced identical results at the same point in windows.
Anyone out there experience this same problem?
