Is there anywhere that check my computer by logging in to my PC remotely and to find errors and get it running to its full potential. It has run perfectly for months and feel I have done something to my system today. It started when I forgot my password and eventually reset a new one. to be frank I don't know how to get it back to when it was running ok earlier today. I even did a system restore but then I spent ages restoring my Norton Security software as it disappeared when my computer started up. Got it back but to be honest I don't know what to do next.
