It displays the windows 7 loading logo pulsing forever without loading up the desktop.
Looks like a PCI Express connectivity fault. These are the steps I would take in that order
a) Remove card
b) Inspect Card for damage to the PCI-E connectors. Inspect motherboard for damage to the PCI-E connectors
c) If ok, reseat card and try
d) If not ok, use another 16X PCI-E slot
e) If not ok, use a PCI-E riser cable, and try a few PCI-E slots
f) If not ok, try another motherboard.
g) If ok on another motherboard, boot windows in safe mode and remove all catalyst drivers
h) Reinstall catalyst drivers
i) If it still fails, try Linux
j) If it works in Linux, then it's a Windows issue.
