I had problems with it even getting passed the BIOS. Found out I had to reflash the BIOS to accept the CPU, I also had problems with setting GPU and overclocking items at "Auto." Once I got passed it I installed Windows 7 Ultimate 64-bit. Loaded all the drivers ATI Catalyst, MSI's drivers, monitor drives. I was in the action of downloading WOW 7.5gb. Left the room, and when I came back I had a BSOD. When Windows finally was able to boot back up to the normal screen. Everything that I had installed EVERYTHING was gone. The screen resolution was set as low as it can go, and I still get BSOD.
I changed the BIOS to "load optimized defaults," and load fail-safe defaults... still got BSOD I did a search and saw that someone directed another person with a 890gx and BSOD to run a HD diag, and Memtest86. No problems found.
