Last night I tried installing a second Asus Raedon 4850 (so that I can crossfire). I went to ATI's website and followed the directions to which it said that the CPU should "read" /"pickup" crossfire. Well it didn't so my first thought was that the new video card was bad.
So I swapped the video cards around and both of them worked after a few resets I was able to see the start up process on my monitor..ok great.
Now i am thinking it's a bad PCI-E slot. After I tried changing them out (making sure I always ground myself) I tried to turn on my computer and all I got was a flashing green light...nothing else would turn on. I can't even get the power light on my CPU.
I took the battery out to "reset" the CPU and nothing happened.
