the exact same thing happened to me a few days ago, 12V was very
unstable, going up and down between 11.5 and 10, and sometimes dropping
as low as 9.5, while this unstability was occuring my radeon 9700pro
would produce the same type of artifacts that you mentioned.
what i did was to open the box and rearrange the powerconnections a bit,
i have a 550w powersupply, with to cables coming out of it, and i had
alot of heavy stuff connectet to one of them (3 disks, fancontrol etc.
and the radeon itself) i swapped the radeon over to the powercable that
only had some minor stuff attached to it and it's been fine
since....dont ask me why, but atleast it solved the problem. and 12V is
now nice and stable at about 11.8
