Okay! More details:
Here are 3 stills of his case:http://img440.imageshack.us/gal.php?g=p0110101911.jpg
On one you can see abit of the mobo code. And I guess it says:
Msi Ms 7525 Ver 1.0 mainboard
He has bought a CORSAIR cx400w, and the card still does not work.
The card DOES, however, work with his friends pc.
The boot is set to pci-e agp.
!!!!!IMPORTANT!!!!!: When the card is inserted, the pc doesn't get past POST. It doesn't even get to the boot screen.
If the card is taken out, everything is as usual.
That made me think of the psu in the first case.
What could be keeping the pc from starting with the new card? -Not the PSU, The card works. The mobo (if my prediction is true) is more than sufficient.
