all the icons on my screen have gone white and i cant click anything not even the start button. when i bring up the task manager all it is is a white box. i can login in fine but that is it. when i try torestore nothing happens, i dont have any restore points so i dont want to do a complete restore if i can avoid it. i have tried running chkdsk in safe mode but nothing has worked. i have also run avg rescue cd form a usb and it identified a trojan but i deleted it, still no effect. i have also tried using the recovery cd i got with my samsung laptop but can only use the startup check tool. this comes back with no issues but i cant use any of the other options. any help would be greatly appreciated!!
