I tried to fix this problem once but it would appear the first person was unable to resolve it.
I have a very strange problem, once it boots up, and i choose which profile i want to use the screen begins to have large horizontal flickers as i move the mouse and if i move the mouse too much the entire screen goes black. I am unable to use the computer long enough to boot up safe mode and it only works during safe mode which leads me to believe it isn't a purely hardware problem.
My computer reads that the cpu usage is at 100% when i open task manager and i can't do much. If i was unclear, the screen is totally black with the exception of rare flickers of the desktop, even though i can see the desktop it is far from usable as it immediately flickers to black and processes very slowly. I apologize if i incorrectly made another post but i received no word from my previous post. http://www.bleepingcomputer.com/forums/topic255661.html
