I have an EVGA 780i motherboard, and I just recently installed an ATI 4870 graphics card. It worked for a week or so, I installed all the drivers, I could play games and everything, but now I have a problem. Whenever I boot, the fans whir really loudly, the LED screen on the mobo reads "FF" (which I think means successful boot), no beep is made, but the monitor is blank. It does not register anything, it just stays on standby. When I take out the graphics card and boot, the fans are MUCH more quiet, but still no beep is made (maybe the beep isn't necessary?)

All the fan noise is coming from the graphic card, that is why everything is much quieter with the card out......the GPU fan will run at 100% initially, and they are pretty noisy at full speed. However, it should throttle back as soon as you hear the successful POST beep....... It is odd that you are not getting any error beeps, but FF does mean a successful post. Try removing and reseating your memory. If you are overclocking, set everything back to normal.
Btw, it's a dell monitor, in case that helps in some way.
The light stays on orange for standby, and says that it has no signal.
