sorry

i should add that PCI slots can sometimes be picky (not too sure technically why) try re-arranging whats in the PCI slots too

i had a prob that mucked up all the slots when i removed a PCI modem, shuffled them around and left the modem in and hey presto :)

yes the screen does go black 'cause you switched it off

manually power down and restart with the new card in

and yes, i dont know why it worked with the modem in, but, it did

this was a while ago with an old voodoo 3 PCI, memory went out of range when i removed the old v56k modem

i just lived with it in : / maybe some proper tech will tell you why or how to get rid of it completely. no one i know could explain why this was a prob

i suggest disabling the onboard gfx in the BIOS on restart or before you install

or at least through the device manager

Very simple.

Make sure the monitor connector is properly inserted in the the new card.  Proceed to power off the pc and turn it on.  press, i believe is the F2 or F12 key/s several times before anythilng shows up in your screen, this will take you to your BIOS selections, select the "AUTO" or "AGP" slot  feature in the graphics selection, for BIOS A02 should be "AUTO" save this settings when exiting BIOS.  When in windows, your screen will look like caca, but that's OK, just make sure to now install the software that your card came with and follow the instructions it will automaticly reboot and you should have now a better view of your desktop.  Right click in an empty space at the desktop and select properties, then settings, then advance and set your monitor to 85HZ refresh rate, and then select the new video card settings and play with'em until satisfied.

Good luck (I know is not that simple, but you can do it)

Happy gaming (nice card you bought)
