I'll start with a few questions that I'd like answered, but this all revolves around installing a new card (Diamond ATI Radeon X1950 AGP 512MB). Is is at all possible to fit (even if it doesn't work) an AGP card into a PCI slot (not PCI express, just PCI)? Will it physically fit? If not then I am pretty sure I have an AGP slot, it's just that under the "display adapters" tap under system information it shows the card under a "PCI" slot. It doesn't make sense to me. As far as I know the slot types are incompatable with one another physically. So, hoping I do have an AGP slot, which I am also more sure of since I popped in the card and hooked the monitor up to the card and it seemed to work, I mean I was able to start XP and everything, so I assume the card is working and therefore the slot must be AGP. Anyway, I got as far as installing the drivers with the CD and it prompted me to restart, but now the computer never gets passed the main boot up area to the windows startup. It just keeps restarting. I can enter safe mode. I have an HT Pentium 4 3.06GH processor, 2 Gigs of RAM, previously what I assume is an AGP ATI Radeon 9550 256MB graphics card as I recently missplaced the box, and Windows XP service pack 2 installed. New 550 watt power supply. Help me please. I can't get ahold of any tech people.
