Hi all just recently outta the blue I have been getting problems with my keyboard and mouse for example I will be running in Half-Life 2 and suddenly keys lock and I keep running in the direction and often whislt this happens I cannot move my aim with the mouse either.

Also another example is when I crouched in a corner (holding control) I could not move the mouse save some tiny little jolts of movement, also in gmod when going through the in game menus theres a large delay from when I put my mouse over the thing I want to spawn or whatever and when it acutaully highlights it in the menu. The keys dont appear to stick and I am confused as to why it has suddenly started and whats causing it. Thanks for reading.
