Task bar suddenly becomes grey and returns to its original color in a few seconds, but volume control and wireless gets disabled. Things are back to normal once i restart and some time later the same issue crops up. any advice? thanks in advance
If this happened recently and you have an idea when it might be simplest to run System Restore, which will keep your own stuff. It usually goes very well - you just sit back and wait for it to finish. You choose a restore point with a date before it happened. This might seem a bit ambitious for what could appear to be a simple fault but these intermittent things can be a devil to fix so it's often the best way.
Always pop back and let us know the outcome - thanks
