can't install any amd drivers without windows locking after reboot

[jjshabadoo]

Tried to use all the threads here on how to load amd 11.12 driver and then use older sdk.

i can't even get 11.12 to load and reboot without lock up at windows logo screen.

windows 7 pro 64 bit SP1 fresh install.

WTF am i doing wrong? I got it work on two other winds 32 bit machines, but nothing on this one.

specs:
msi 890FXA-GD70
2gb ram
amd sempron 145
seasonic x1250 gold
5870 in slot 1
5970 in slot 3
5870 in slot 5

any suggestions?
