Hi all,
I've encountered a problem that I was hoping some of the more
technologically experience among the group might be able to help me
with. I'm in the process of trying to Frankenstein another couple of
years out of my already ancient PC by upgrading the video card. I've
already managed to max out the memory to 3GB and have added a 500 GB
hard drive. Now, I just need to upgrade the video from the pathetic
GeForce-2 32MB AGP card to the ATI Radeon X1600 PRO 512MB AGP card I
recently picked up from eBay.
Everything I've been able to unearth says that the card ought to be
compatible with my mother board, which Gigabyte nForce3 250 MCP AGP 8x.
I have a 400-watt power supply, so I'm fairly certain I'm getting enough
power to run the thing. Problem is, when I seat it into the AGP slot
and connect it the VGA, the thing simply will not boot and there is no
signal going to the monitor whatsoever, though there is power going to
the card and the fan is clearly operating. I tried disabling the
current drivers for the old card before installing it -- same result. I
tried installing the legacy drivers for the Radeon beforehand, as well
-- which somehow managed to disable my USB wireless adapter until I ran
a system restore.
I've gone into the BIOS to see if there are any settings I might be able
to change -- voltage, manually enabling AGP 8x, etc., but have been
unable to find anything that would seem to be the problem.
Any ideas what may be my problem (aside from the fact that I'm using a
PC with Win XP, which there's not much I can do about at the moment?
Thanks!
Walt
