hi
that seems to be the problem the old driver was 5-1-2600
and the new driver is 5-1-2600-1152
i have now rolled the driver back to 5-1-2600 and run 3d mark 2003 switched computer off for 5 min and it started no problem
so its the old saying
IF IT ANT BROKE DONT FIX IT
never thought it was epox fault for one minute
