LINUX just WON'T INSTALL!!! Help URGENT

I have an Alienware ALX Desktop.

Pentuim Core 2 Duo is the processor.

I have tried SUSE 10.1 and Unbatu 6

These are the results I get...

SUSE 32 BIT VER: After clicking Installation, the loading screen takes about 10 minutes, and the black screen with white text after that, goes all the way to the bottom and freezes at 6%. I waited for an hour...

SUSE 64 BIT VER: After clicking Installation, the loading screen does not load, meaning I never reach that black screen with the white text.

Unbatu 6 32 BIT VER: After clicking Install or Start or whatever that option is, It has a black screen with a flashing white "_" in the top left corner. I waited for an hour, and this does not change.

I have defragged my C: disk before each reboot...

SOOOO... What the hell should I do?
