I have an agp 4x slot in my computer ( Dell Dimension 4500 ). The other day the video card that came with it starting making noise ( geforce ti 4200 ). Within a few minutes the display on my computer was not appearing. I opened up the computer and removed the graphics card thinking that the card blew out, since I've had it for about 4 years. I have no onboard video, so I had to order a new card ( Radeon 9600). I just got the new card, inserted into the agp slot and there is still a black screen. I know it's not the monitor because I hooked a laptop up to it yesterday. Is it possible that my agp slot is busted? Is there a way to tell? Does anyone have any advice on what I should do? Thanks in advance.
