we always recommend buying the case and power supply as seperate items
case and supply 50 pounds
you would expect to find a power 650w supply costing 60pounds+ on it's own in there
try reinstalling the drivers again
in the device manager uninstall the card
reboot tapping f8 and choose vga mode
when windows finishes rebooting
disable a/virus
install your drivers
reboot the computer
