Hello all,

I have just recently bought an XFX 1GB 8600GT graphics card for my Dell Dimension 5150 PC, and am having issues with this new hardware change - namely a blank screen when i attempt to restart the computer. The entire system seems to turn on - harddrive activates, motherboard light is on, the fan on the graphics card spins, but i get no display on the screen. There are led lights - 1234 - on the front of the del - it is only getting to 4 (but i dont know if this is because it is requiring me to make some changes for the new hardware - i cant see the screen :S

I have replaced the graphics card with the original Radeon X600 for the mean time, and I am hoping that someone can walk me through in stages exactly how i should go about installing the new one.

I have already uninstalled all ATI, Control Panel and Uninstaller software from the computer, and used a driver cleaner to remove traces of the old ATI drivers. (I believe the computer is currently using internal graphics) Actually fitting the new gpu is not a problem, but a walkthrough would be very useful because i must be missing some steps. Thank you.

Also - it has just occured to me to query the significance of my monitor and computer working correctly when i return to the old ATI graphics card? Im not sure.
