I have recently moved into a friends house and have my computer about 2 feet from the television he gave me to use. The TV is a flat screened RCA rear projection ("old" tv style). The computer is "white box" (my boyfriend but it together) although the case does say "Dragon Soyo" There is no cover on the case because the system overheats with the case/cover on. The monitor is between the computer and the television, and is an Envision brand (regular, old rear projection style). I did not have any problems when the computer was located at my old place. The television is hooked up to cable. The low channels work with out interference, some channels work for about an hour while the computer is on, then go fuzzy, and some channels have constant noise that just gets worse the longer the computer is on. The noise is MUCH worse with the computer on, but is still noticeable with it off. What options do I have for reducing the noise? If I need to put a case on my computer, what are my best options for cooling the computer so it doesn't overheat?

"There is no cover on the case " This is part of the issue. Might just be able to install a muffin fan in that case or two.Case's, even plastic ones form a shield. Plastic ones are painted with a conductive paint to form a shield. Best choice would be to use the on-off switch. Do you really need to have both on at the same time? You would be better off also by moving the computer away would be my guess too. Might loose magnetic data if too close to an older set. "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
