I turned my computer on one day and I got the normal Asus screen, the next screen SHOWING the harware was black and snowy but it then BOOTED to windows.

After the next reboot all I got was a black snowy screen and it never loaded windows.
After talking to some peeps the consensus was that I had a MOBO failure.

I just replaced the mother board put everything back TOGETHER and when I boot up the computer I got the nice Asus screen then it went righ back to the snowy screen and does not load windows. I believe the OS is not loading cause when I press the power on button it shuts right off. I do not need to hold it.

What could this failure be? RAM failure? Video card?To test the RAM DLoad and run MemTest...let it run for a few hours.
But it's probably the video card.
I doubt it was the MBoard.You could try getting new video card to test to see if problem goes away. f Memtest has NO problem reading RAM, then it could be video card's problem.

Or you could t ry getting a hold of a second computer and install your video card on ait ND see if that second computer has same problems when loading to windows.
