Pull the mains power and wait 20 minutes for the caps to fade. Then whip the lid off and give it a thorough dusting-out. Have a very close look for any signs of localised frying, particularly around the PSU area.
But still be very careful with what you touch- you could still get a belt!

oddly enough... ****** media called today and said there was a problem with my signal !!
she said " Your signal to Noise is WAY too LOW " engineer is coming tomorrow !
Do you think this could be my issue , because come to think of it , this has only been happenin in
the last 3 or 4 days , which is also stopping some websites being displayed properly !
If your sig to noise was way to low then they could resolve that at the cab or centrally, without the need to visit you. Also they would not readily know unless you reported a fault !! Sounds very suspicious!
