Problem is when I turn the machine on it loads to the Wallpaper but the part where I login isn't there. I can see the pointer but thats it. The pointer is responsive. I've tested the hard drive on another machine and it passes. I've installed a fresh instance of Windows 7 Pro on another drive in this computer and the computer seems to be sound. Machine was working fine up until last night. OS is Windows 7 Pro 64bit.
Safe mode loads to same screen. Last known good config does nothing to help. When the wallpaper loads it will blink sometimes. The cursor is still visible during the blink. I've also attached an external monitor and again no help. I don't think its software since a fresh install works fine on this machine.
