, checked the BiOS to make sure everything was being recognized. When I re-booted it hung at boot menu as if I was holding control, before the OS loaded, so I knew it wasn't a problem with Windows. I also tried some other half-baked fixes I discovered online such as pressing the control key five times or pressing both left and right control keys at the same time, nothing worked. After a lot of browsing on my other computer I came across someone who seemed to have at least diagnose the problem. On my computer if you pull up the on-screen keyboard, you will see that the control key is constantly highlighted as if it was being held down. If I unplug my USB mouse, it solves the issue. Plug it back in, and the control key go right down again. oddly enough if I boot with the mouse unplugged, things work fine and if I plug it in, things work normally. Oddly, the exact action that causes the computer to act this way, is using the scroll wheel. If I don't boot with the mouse in question and switch to it without using the scroll wheel I can, and have, used the computer for an extended amount of time. If I move the scroll wheel one little notch though... Switching to a different mouse didn't solve the problem at first, but if I boot up with a different USB mouse things work fine. So I have narrowed things down a lot but have not managed to solve the problem.The mouse in question is the "Sharkoon Drakonia"
