I've recently changed my computer case to a new, bigger case. However, after I changed this case over, I can no longer watch TV due to interference with the signal.
I have removed every output to my computer (e.g. internet, visual, sound etc) which has not changed the affect at all. I have bought a new PSU which did not change the problem.
The aerial is in the loft above my PC but, this was not an issue before I changed my case.
I noticed a change in the interference when I removed my water cooler and replaced it with a stock CPU cooler. The interference then "moved" from the originally affected channels to some lesser used channels.
Could anyone suggest what is causing this interference?
Thanks

It sounds like your new case has a lot less metal than the old case, and is allowing signals from the CPU (and the motherboard in general) out. The CPU heatsink is closely coupled to the CPU chip, and acts as an antenna for those signals. Undoubtedly, the electrically-conductive parts of the conventional (air-based) cooler have different resonant frequencies than those of the water-based cooler, and this would explain the shift in frequency of the interference you're experiencing.
