New Debian install problem

[Mike Allegro <mikeallegro71@gmail.com>]

I just installed Debian 5.0 and it seem to install just fine.  After the 
installation I rebooted my computer and Debian Linux loaded up, when it 
goes into the graphics part I see a blue screen with a symbol that 
reminds me of the hour glass symbol from Microsoft Windows. After the 
symbol disappears it should go to the login screen but it does not.  It 
goes to a solid white screen where there is nothing but the mouse 
pointer.  I am not sure what is going on?  Do you have any ideas?  Could 
it be a problem with my graphics card?  I have the following in my computer;

AMD 1.2 Ghz processor
512 Mb Ram
Diamond graphics card with ATI 9250 chipset with 128 MB ram
80Gb hard drive
CD Drive
CD Burner


Any help would be appreciated!!!

Regards,

Mike
