If that computer is in use while someone is watching TV, then you will need to find a way to reduce the EMI that it is creating. Maybe one of these ways:
1. AC line filter for computer
2. Power supply with better filtering for low EMI
3. Better shielding for computer case
4. Is the monitor creating EMI?
Does the computer have a 3-wire power cord that has the grounding pin connected to a properly wired 3-wire AC receptacle?
