I have a Thinkpad T500 with ATI switchable graphics. On most boots and sometimes during use, the desktop will crash and require restart (the desktop, not the whole machine). The error is as follows:

It is running discrete graphics – so it’s not switched to low power mode. I have tried adjusting the graphics properties but have not been able to isolate the problem.
This is a Windows Vista Ultimate system. There is no newer Catalyst driver available from Lenovo.
Anyone have any experience with this?
Thanks!
