brkkab, yes I did actually have an unrecoverable BSOD at the start of the year, I fixed all that and installed well over a hundred updates, after a while I got fed up of trying to install updates that wouldn't install and turned updates off. I've run full virus/malware scans etc... I also got the correct hardware drivers from the Acer site and not from Windows. The system tray thing isn't happening now but the double click / select then enter on the shortcut is doing that again. I'd like to know why it happens... why the first double click is not recognised?
