I have a Asus M2N Motherboard with Nvidia GT 240. I ran the windows 8 pro upgrade
from windows 7 home it failed and reverted back to windows 7. Then I tried a clean install
and the Windows 8 install screens were Fuzzy\Blurry from a clean boot from windows
8 pro disk. It managed to install, activate, and rebooted once after it installed windows updates .
I used it for a couple of hours and windows 8 pro ran great. But the next time I rebooted I got
nothing but a blank screen as if the computer was shutdown. The monitor had a flashing power
button, but the computer was running. I tried dual boot with windows 7 home and it seems
that windows 8 has a problem with this motherboard. Any install, pre bootup screen always
has Blurry and Fuzzy graphics.
I also have another computer I upgraded. it is a Asus A8N-SLI Deluxe with 2 Nvidia gt 8600
graphics cards. Everything installed ok and runs great.
