Here is some general advice, from time to time and as PCs get older they exhibit forms of instability. Now, in most cases a cold reboot will clear the problem, i.e. switch the PC off, leave it for a minute or two then switch it on again.

However, if you still have the same problem after several cold reboots then you will have to seek professional advice because something is going wrong (about to fail).

Hope this helps.
