R500 Windows 7 Screen problem

[freesoft]

Hi

Model: Thinkpad R500
OS: Windows 7
Lasted driver from lenovo.com, can't install the one from intel.com

See the two screenshots:

The problem is not only in programs, sometimes it does it allover, with nothing open.

I got the motherboard changed twice in service from Lenovo, but that didn't help.
After first time, the problem was gone, but returned in a month.
They say I should use Windows XP, because the computer was shipped with it.

Any suggestions ?

I've got a suggestion at forums.lenovo.com with a link to Visual corruption - ThinkPad R400, R500, T400, T400s, T500, W500, X200, X200s, X200 Tablet, X301.

And that seems to have fixed the problem, so case closed for now
