Question about E-Machines eMachines Desktop PC
If everything is powering on and your getting no video, most likely the motherboard has gone out. With a agp card present it disables the on-board vga. Does it sound off any beep codes when you cut it on?
First thing i would do is take the memory out just to make the computer beep and acknowledge that there's no memory present, if you don't hear a beep, there another problem, if it does beep however you can assume the motherboards okay and go onto step two. It just might be bad memory too, see if you can replace it with memory from a working computer.
If you've been taking out the video card alot, i would make sure its seeded properly. Then take out some of those cards your not using. 56k modem, sound card, etc. I would also try just the on-board video, too.
Then if your still getting no video, i would remove everything from the board, ide cables, cards, usb controllers and cables, just have the power supply and the wires for the power and reset buttons connected. if you dont get at least the post screen, then its a bad motherboard for sure.
Sorry to type an essay, buts thats how i approch video issues like this. If you don't feel comfortable with doing major surgery like that, please don't. Most likely you can take it to a repair center and at least get a diagnostic, and put the fear of making things worse, in there hands.
