Ok. So I have been living off this computer I got for $400 WAY back in when (late 2002) for awhile now. I have been taking any and all parts I have been able to get my hands on to upgrade it along with a LOT of self done windows mods to keep it in the race. Well I just lucked into some new upgrades from a friend that is moving and tossing out a few old computers. An ATI Radeon X 1600 Pro and an Celeron 2.* (He is not sure what it was). So all is go I go about the normal installing them all into my system. BUT once they are in and I boot up I get a blank screen. So I change back and just try them one at a time and get the same thing. I have NO idea why... any ideas?
