Black Screen Problem for disabling the graphic adapter

[cenobite321]

Ok, this is the story:

I have a Compaq X1000 with a Mobility Radeon 9200 card and a Windows XP OS.

I recently got problems with my ATI card because after 5-10 minutes of having my computer on, the screen started to jump and it froze, having me to reboot my computer. After that I just disabled the ATI driver (via adapter's propierties), hoping that solved the problem, but it didn't. So, hoping that the ATI was now fixed, I tried to change from the VGA (the default that the computer has) to the ATI, but I couldn't, so I (foolishly) disabled the VGA adapter (also via adapter's propierties) and I rebooted my computer, but when I did, I just had a black screen, although I could still hear the sound.

Can one of you please help me to solve this and return everything back to normal? Thanks

you need to enter the bios during boot up and enable the video adapter.

My bios is like this:

You can only choose the next options:

File:
System Info - Detects there is an ATI card BIOS date: 2003/05/20
Restore defaults - Already tried it
Save Changes and Exit
Ignore changes and exit

Security
Admin password
Pwr on password
DriveLock Password
Device Security - Everything is enabled here
System IDs - I don't know what this is

Tools:
Battery Calibration - I don't think this is important
HDD Self-Test options - I ran the quick test and it said: Error: Read failure

Advanced
Language
Boot options - Multibot is disabled and the boot order is First: Optical Device, Second: Hard Drive
Device options - Parallel port mode: ECP
USB Legacy support: Enable

Ok, this may sound stupid, but is this the BIOS? or do I need to press something else at the start?
