Yesterday my rig crashed and won't reboot........

I started to play Black & White 2 and then it locked up.....
I rebooted and got as far as windows login then the GFX was messed up......The GFX card was not OC'ed as only reinstalled drivers earlier last week.....
I tried pulling out the battery and clearing the CMOS.....It booted but gave me a warning the Bios was in safe mode.....It gave me the option to press delete to change the settingts for press F1 to contiume booting
If I press delete --> it's ok untill I save the bios settings, then nothing.....
One diagnostic LED on the board stays lit (gfx prob?)
If I chose F1 --> It boots into windows fine, untill it gets to the XP screen then gfx is messed up.
I re-flashed my boards bios twice, once via Tmods boot cd and once via floppy (blind flash)
Now I can't get any display.....the monitor gets no signal @ all

I have no internet access as my Intel rig is running Linux and I have a crappy usb wifi adapter which won't install on linux (using NdisWrapper)
I was thinking of doing a blind flash of the GFX bios.......but the card is still under warranty and if I mess up the Bios then I may not get an RMA
The worse thing is my Linux box has no Video Codecs installed and my XP rig was my TV and entertainment centre........I have nothing to watch @ all or no web access and I'm on lates this week

It could be the mobo or the GFX card, but I don't have a second PCIe card to test with.......
I've taken apart the rig and tried to boot with just the GFX / 1 stick of ram and nothing......
I'm going to bring back the card tomorrow morning and hope that was the prob......I'm also thinking of paying a bit more and upgrading the card for an ATI card....
I'm thinking it's the card as If I only have the my OS HDD in and press F1 I it loads windows...I even hear that poxy welcome to windows sound, but the monitor gets no signal

I'm using the stock bios in the GFX card.....I did try a modded bios, but that was 4mths ago.....adding more voltage didn't help my OC so I reverted back to the origional Bios......
This week and prolly next week will be a killer for me as I now have nothing to watch @ all.......I'll haveto revert back to using ethernet to connect to the web via my Linux box......
someday I will have a stable pc.....yeah right!!!!
