I have tested the card with my both PCs.
Both PC could not start with card but running fine with my old XFX 7600G.
Yesterday went to Tirupati for RMA.
They took my card and told me to wait.
After 1hour they told me there is no problem and show me running the card with 3D Mark.
But when I ask for temp. they denied to show me.
When my card gone kaput temp. was very high but Speedfan shown 70C.
And even the surface of the board of the card was more hot cos when I touched that my finger was almost burnt.
I think they done some thing with the card between that 1hour.
still card running very hot.....

I'm totally confused.
Is there any method(software) to check video card if that is OK or not ?
