Replaced AGP card near PCI card and blind is blank and remains blank when I reinstall infirm AGP card.?

I installed a unknown PCI video card and my screen is very soon blank. I took it out and put in the out-of-date AGP one and the screen remains blank. How can I engineer the computer work to at least see what is going on?

Answer:
Some computers enjoy settings in the BIOS that involve to be changed. Depending on the brand of computer/BIOS, you'll need to hit any ESC, DEL, F2 or some other key at the drastically first screen you see. Of course, the frist item you need is to achieve SOME video back so you can do this. I'd try reseating the frail AGP card. AGP can be tricky sometimes, just clear sure it is pushed all the instrument in the slot. Hopefully afterwards your video comes back. If it does, travel in to BIOS and look for an advanced or divergent menu. Find something that says Video. It should hold options such as AGP, PCI, Auto. Selecting any Auto or PCI should work. Then save and reboot. Replace the PCI card and try it out. Good luck!
The PCI slot may own accumulated dust for sometime. Try cleaning it beside a small brush then reseat the PCI video card thrice.
But help yourself to note that the PCI bus is SLOW for 3D graphics. PCI slot will freshly slowdown any good graphics card.
try this

reset the bios(look at motherboard manual)

later load the defaulting when you've insert graphics card

install the pci driver
