That is NOT a problem with your computer. It's a problem with the wiring in your house. If you rent, tell your landlord. I'd wager that your building must be pretty old. Try making sure your rig is the only thing on its circuit.
Here is where it is very strange, I just got my electrician to install a new dedicated line into my room, he came by today to check on it and says that the line is fine... The line is a 20 Amp line. Now why does my computer only do this when out of sleep mode? It does NOT do the same thing when I turn it on from shutting it down
