ATi 4850X2 + Windows 7 = Fail

After installing Catalyst Drivers 10-3 on my Windows 7 x64 Fresh install, I got a black screen of death. I was able to turn it off and boot into safe mode. I uninstalled the drivers and tried 10-2, then 10-1, then 9-12. I don't understand why it won't work.

My PC

AMD Phenom II X2 550 BE Stock Cooling no OC

3GB DDR2

ASUS M4A78 Plus Motherboard (AMD 770 Chipset)

1x250GB 7200 RPM SATA HDD

1x160GB 7200 RPM IDE HDD

Sapphire ATi 4850 X2, no overclocking.

Onboard Realtek Audio

I also have installed 10-3 Southbridge Drivers and Realtek HD Audio 2.47 Drivers. I'm considering going back to Vista, at least that worked.

  1. What PSU do you have?
  2. Did u install the right driver(64bit ver)?
  3. My PSU is Antec 650W TriRail. The PSU calculator said it was fine.

    Yes installed Win7 x64 drivers.

    I just wiped my hard drive and installed a fresh copy, and I am still having driver issues. Are the Win7 drivers good enough for gaming?
  4. Then try the one which came on the CD with the card, sometimes the older driver is more stable than the latest one.....
    And make sure all the cables connector are properly connected.
  5. Sometimes the windows update drivers are better because that is the one they tested and worked on the OS.

    I am not sure how thorough they test the drivers, but try different ones until you get a stable working one/
  6. if i'm not mistaken 4850x2 is made by Sapphire alone and not officially supported by ATi like 4870 x2. try to get driver from Sapphire site and not from official AMD game site
  7. Ok, thanks for all the help guys. It turned out it wasn't the drivers like I thought it was.
    I had forgotten that I had installed Ati Tray Tools, which turned out to be the problem. I apologize for wasting your time.
  8. Haha- ATI tray tools will do that to ya;-)
