Hi All. I started having a problem last night with my PC. I bumped the case with my knee, started getting artifacts on monitor immediately, BSOD, then shutdown. Wouldn't boot up, although I could hear the HD spin up.
I restarted the machine and notice the Sapphire Radeon HD 4890 GPU blinking 3 led lights. Fans were making a funny noise, sounded like the power was surging/fading. Loud whir, then soft whir.
I shut down, unplugged, grounded myself, and discharged power (reset button). I unplugged the GPU and reseated it. Successful boot. Shut down again to reconnect everything and move the box back under the desk. Same problem as before. Reseat GPU again, but no dice this time. Tried the card in the other PCI slot, same issue.
Finally, I tried switching out the GPU to an older Nvidia I had laying around. Worked like a champ. Looks like the card.
Anyone had to return to Sapphire before? They don't even list a U.S. contact #, so I submitted a support ticket and sent an email to their RMA email addy. No auto-reply to either doesn't exactly give me a warm and fuzzy.

well it may be the card or it could be a faulty power supply. does the fan on the graphics card spin? maybe its overheating? you said you bumped the case with the knee, maybe some of the pci-e pins got scratched?? or some cable came loose?
The GPU fan does spin. I took the card out and visually inspected the pins. Nothing looked out of the ordinary there. I checked all cables (unplugged and replugged). Guess I'll be RMA'ing the card. Thanks for your replies.
