Windows 7 ATI x1200/Xpress1150 driver problem


New Member
I've Win7 B7100 x32 (clean inst)
I've a ATI x1200 motherboard/intergrated graphic card (says the manual).
Windows doesn't recognise it.
I've tried installing Catalyst 9.4, 9,3, 9.2 and 9.1.
The only one finding my graphic card is the 9.1 and it installes a driver för Xpress1150.
Fine! But every now and then my monitor says theres no signal and turns black. The only thing left to is to hard reset the computer.
It seems that its depending of what I am doing on the computer. If a leave it, it will work properly. But if a start some programs it won't be long before it happens.

Thank you for your help.
