[newbie]HELP: Athlon, M7M and Radeon

[Serge]

Hi

I would like to know if someone has these 3 components :
Athlon [500 MHZ]
K7M motherboard
Ati Radeon

I cannot make my X works with the Radeon...With Mandrake 8.0 .
During the  configuration test i got blank screen [sleep mode] and the pc 
crashed

I tried RedHat 7.1, it worked during the X configuration, i logged in once as 
root, and then when i logged out, blank screen [sleep mode] and 
the pc crashed...


Help please!!

Thanx Serge
