Monitors - [Answered] Monitor posted in the Hardware forums; Monitor problem
Loud noise, crackling sounds keep coming from inside the company case and the computer gets hot very quickly....
Make sure that your power cable is connected to the monitor correctly.
When you say "Computer gets hot quickly", do you mean the monitor?
If the power cable doesn't resolve the problem then it is probably components within the monitor that are damaged. Could be anything from the capacitor to the cathode ray tube.
I personally wouldn't recommend trying to fix the monitor if you have never done so before.
Go with Zimbo on not fixing yourself. There are parts inside that carry so much charge they have been known to throw people across the room when touched.
