I run the benchmark fine until the last 2 tests(pixel shading and whatever #15 is).They are both DX8 tests.Is their something in powerstrip that I might have checked-unchecked that would give me these errors or is their a way to re-install DX 8.1?I ran diagdx from the start-run command and it passed the tests.I don't know what to check or uncheck on Powerstrip to enhance my performance and might have done something trying different settings out.But come to think about it, If I remember correctly this was happening before I installed it.
