Last week I bought the Sapphire HD5850 from my brother. I was still using a Sapphire HD4850, so I thought it was a good upgrade.
So I followed the normal instructions of how to install the graphics card. Everything went fine until the reboot after the installation of catalyst 13.1.
After the boot of windows 7, when the logo has gone and normally the login screen shows up, my PC blue screens, shows a black screen or the screen is showing half the login screen (which is frozen).
At the BSOD it says atikmpag.sys is involved in the crash, so...
I have tried everything I could like using older drivers, tweaking the power supply to the graphics card and so on, but without a solution.
But when I put my HD4850 back in it, it will just work fine again...
OS: Windows 7 64-bit service pack 1
Motherboard: MSI P-45 NEO
CPU: Intel Core 2 Quad Q6600 @ 2.4Ghz
Powersupply: Cooler Master Real Power M520
Additional Hardware: 1 HDD, 1 SSD, 1DVD RW drive, 3 case fans and a network card
I hope I gave enough information so someone can help me with this.
