There are a few things that can cause no display on the monitor. That single beep means POST = Power On Self Test. Post has tested everything on you're board to be good. The cable between video card & monitor may be bad or not connected correctly (Swap out the cable as last resort). 2. You're monitor is defective, try swapping it with known working monitor. 3. You're video card is not functioning. Lastly, when you reset the system cmos/bios everything went back to default. This means you're bios is now using the onboard PCI video graphics. Remove you're radeon 9600 video card. Try booting the system. You should see display again. The only way to test you're radeon would be to boot to the bios & set bios to boot using the AGP radeon. You need to change Init Display First to AGP & not PCI. If you loose video than you know you're AGP card is bad. Reset the cmos/bios before adding another AGP card or you will not get display. This setting is on pg 3-5. Integrated Peripherals. If you need you're manual you can download it from this link: http://www.abit.com.tw/page/en/motherboard/motherboard_detail.php?pMODEL_NAME=NF7-S2G&fMTYPE=Socket+A
if it happens with external monitor then it's probably video card.
most likely a cold solder joint on the board. OR if it's a plug in type board it might just need to be re-seated.
there are 15 Pins in Monitor cable which is connected to VGA port on the rear side of the Tower. First, we need to reset BIOS settings, and then try again - onboard video card only. for Add-on Video card try reseating video card in diff. slot if possible / reseat video card and try again. if it does not fix it, it could be the problem with Monitor RGB Connection - near the electron gun in the monitor CRT tube. resolder RGB , it will fix it.
