Bad static in radio recption when computer is on

[Titanion]

What can cause bad static in radio recption when a computer is on... it is on a computer I build for a friend... NF7-S with a mobile Barton 2500+ clocked at 210x11.5...

Power supply. Had the same problem with a friends computer; couldn't use his short-wave when his computer was on. On a hunch we changed the power supply (which was a cheap unit) to an Antec 330w True Power, and the problem went away. Could be the shielding inside the PS...guessing here, but it's worth a try if you have access to another PS.

If you have the computer audio outputs hooked up to the stereo and the computer and stereo are hooked up to different power outlets, you could get what is called a floating or noisy ground. A possible solution is plugging them into the same outlet, and if that doesn’t work you may try a better power strip.

A long shot, but make sure the FSB Spread Spectrum is enabled in the bios. That's what it's there for.

It's normally caused by using an illegal case or power supply. I say illegal because the parts aren't FCC certified, and it's illegal to interfere with reception (or transmittion). These parts are perfectly legal when located in any location where they cannot interfere with radio reception or communications equipment.

True neon is a real bitch. The harmonics off the high voltage, should be considered an RF jamming device.

Crashman,

Yeah, that's cool, and you're probably right. I just wanted to piont out, that the FSB Spread Spectrum's sole purpose is to prevent what would otherwise be some obnoxious radio interference from the computer.

Some people disable it, not knowing what it is, then wonder wtf. Thought that this might have been the case.

I had that problem, and quickly discovered it wasn't the computer. I fixed it by plugging the surge protector into a different outlet.

Update: I replaced the outlet (with a GFCI), and that fixed the problem.

Does it lack one of these?

That filter both keeps noise generated by the power supply and computer from getting out of the AC lines and AC line noise from getting into the computer.
