Hi everyone, i'm new to the site so im not sure where to post this.
I have a ATI radeon 9800 pro graphics card, but it wont work in my ASROCK K7NF2-RAID motherboard. The graphics card i'm currently using is a GeFORCE2 GTS 32 mb ddr memory That card works in my ASROCK board. But when i put the radeon card in my motherboard. It doesn't work, when i turn the PC on the screen just bombs out.
Any help would be greatly appreciated.

This sound like it is a power issue. What PSU are you using?

I'm not quite sure. But when I had my old motherboard, the ATI radeon 9800 pro graphics card worked then. And I used the same PSU in both boards. But the card just doesnt work in the asrock board.

Did you remove the drivers for the old card before installing the new card?

No because I formatted the harddrive when i got my new motherboard. So there was no old drivers on it.

When you say the machine just "bombs out" does it start to boot then just ppeewwwww and power just drops back off?

Whats the full spec of the machine you are using...including the wattage of the PSU? Is there anything else different about the setup than when you were running that card in the old motherboard?

The whole computer doesn't bomb out, just the monitor.

The whole computer doesn't bomb out, just the monitor.

Does the computer actually boot? (you hear the BEEP and the machine goes through it's POST sequence) Or do you just hear fans spinning and get a black screen on the monitor?

If it is just fans spinning and a blank monitor, my guess would be an under-powered power supply. (I ran into a similar issue when I first got my 9800XT. My old 350W supply was not up to snuff with the demands of the new video card. Once I upgraded to an Enermax 430W everything ran just fine...)

If the machine does POST and actually boot and then after booting the monitor goes blank, you may just have your video card set for a refresh rate beyond your monitor's specs. In a case like that, you *should* be able to boot into safe mode, change your refresh rate to 60Hz, reboot, and then change to a more monitor-friendly resolution and refresh rate.
