I just got a used XFX HD 5850(still under warranty) to replace my HD5670 from one of my friend. After I replaced the card and booted the PC for the first time, the pc booted fine and I was up and running. I shut down the pc and when i tried to restart, the pc is not even going to the BIOS. I have tried reseating the card, have replugged the power cables, reseated RAM but no success. After many tries, it once booted to windows. When i tried to refresh the windows experience index, the screen turned gray. I rebooted again but sadly could not boot to windows. In all these attempts, couple of times i also got the error " Hyper Transport Sync flood error occurred on last boot. Press F1 to resume". After struggling for an hour, i put my 5670 back in and the system booted at first attempt.
Please advise as what could be the issue here. Is it the power supply(Corsair VX450) or the GPU. I dont have another machine to test the GPU. Please help.
