Hello,
I purchased a Radeon HD 4650 (by Sapphire) graphics card over a year ago after asking for recommendations on this board. I was upgrading from an integrated card and had serious space and power requirements for the upgrade. The card worked great for me (some gaming, mainly Photoshop and 3d modeling/rendering) for about 14 months now. THEN...the last time I used this PC, the screen would flicker very randomly. Today I turned it on and it loaded fine until the windows startup/login screen. As soon as this appeared on screen for a second, the display would go black. Logging in with a blank screen and having windows start up did not make anything appear.
I restarted in safe mode, and everything loaded and appeared onscreen normally, except for the resolution being extremely low (running off of the integrated card). I checked my display adapters (both the integrated card and 4650 card) and did not show any problems. I reinstalled the latest HD 4650 driver, and after enabling/disabling display adapters and restarting a few times, I got the display to show up as desired (the same as it was when the 4650 functioned normally). I made the PC sleep and brought it back to see what would happen - now I have a blank windows login screen (shows up for a second then permanently disappears) and once I login, my desktop shows up then the screen starts to flicker in a very set pattern. Its almost as if the screen shows up for a second, reduces resolution for a second, then turns off in a relentless cycle. Is the card toast? I am now running off of my integrated card without any issues. I should mention that I was/am using the same HDMI cable run through the 4650 card this entire time. At $50, I wouldn't be heartbroken to get another card - but would this even fix my issue?
