Tricky Video Problem

Sapphire Radeon hd 3870 video card
February 15, 2010 at 06:05:56
Specs: Windows XP SP3, AMD Quad Core
I have a tricky video problem and I'm looking for some advice on what might be the cause and what to try.
The problem:
System seems to boot normaly but I get no image on screen. After several unpluging, moving card to the other PCIE slot, switching cables, monitors, even a plasma TV, computer starts. One instance I alt+tab from a game( resolution changed) and computer restarted and again same thing, was booting, no image. managed after playing arroud with it to restart it (cant tell exactly what made it restart, last time I just switched the 2 monitors in the 2 DVI slots - which I tried before and didnt work). When I manage to start it, both DVI out work.
Another time I was playing Burnout and the monitor image dissapeared, reappeared 2 sec later, than off for good. The computer didnt crashed because the music was still on, and not on a loop or anything.
I tryed: 2 monitors, plasma tv on d-sub, 2 different d-sub cables( they all connect with 2 different d-sub - dvi addapter) 1 DVI cable. Also tryed the s-video output and nothing.
The system is:
MB: MSI K9A2 CF
4 GB Ram
procesor: AMD quad core something too lazy to check
Video: Sapphire HD 3870 DDR4 512 MB
Power supply: 600W Coolermaster
Thanks

Well, I don't think the drivers have anything to do with the video displayed when you start a computer.They kick in after loading the Windows.I think the BIOS is taking care of that and I've tried reseting the BIOS and still no image when computer starts.
And I cannot start the computer in order to check the drivers. I'm using a laptop to write here.

check the BIOS, do you have video output selection?

( defaults to O/B graphics and you are using other cards )

intel810 -Don't worry ! :)

treveena - I can't see the bios on the screen but the MB doesn't have on-board video. I don't think the default is on regular PCI and not PCIE ecause AGP I dont have. Anyway if this is the case don't know what to do beside reseting the BIOS and it doesn't make it work.
