There are multiple possibilities.
I would focus on making sure the computer case and all attached cables are properly assembled and all the shields are grounded. Also move TV associated wiring away from the computer's wiring (especially monitor and network cabling). And check that your house wiring's safety ground is ok.
Beyond such general precautions, you need to identify the source and path of the interference. Disconnecting things one at a time can sometimes be revealing. If (as you seem to suspect) the computer's power supply is implicated, swapping it for one of better quality might help.
If your TV signal is weak, you may not be able to avoid the problem. Not all computers are well designed to suppress RFI.
If you have any direct connection between the computer and TV, that could be the culprit.
Also check any F connectors between the antenna or cable connection and the TV to make sure they're secure.
Let us know what you find.
