my computer is bleeding the corner closest to it on my monitor. I can't move the comp or the monitor anymore apart then they are, I have too much crap in this small room to relocate it. Is there anyway to shield this inexpensively?

It's pretty hard to shield magnetic energy, but you can try placing a large sheet of aluminum foil between them Try wrapping some foil around a large piece of cardboard. Somehow, attach a wire to this foil and clip this wire to the back of your computer case. This might help some, but I don't guarantee it.


Good luck. :)

Excellent advice from PC Bob. But I wonder if it isn't something other than the pC that is causing the problem. PCs usually have a metal case and normally do not put out much magnetic interference. Do you possibly have some speakers near the monitor.

It is doing WHUUUUT????(!)


What do you mean "bleeding??" I'ts affecting the color?

If your computer is installed in a PROPER steel case, as it should be, there should be no "magnetic fields" affecting the monitor.

Atomicboy, I have my monitor about 3 1/2 to 4 inches away from my case and my monitor doesn't do that. But how old is your monitor?

It's a dell 21", it wasn't doing it before, but now I have put a zalman 7000-cu HSF in it, and some other fans, and a thermaltakte silver butterfly psu, and something is doing it now. When I move the computer closer, the color gets effected more, and when I move it further away (which I can't can only do for testing), it doesn't effect it anymore.

WELL YOU STILL DIDN'T ANSWER MY QUESTION

IS THE COMPUTER housed in a legit, shielded, approved, steel case, or is this a case that you've chopped up, left panels out of, or installed a Window in the side of?

(See, now you've made me say the dreaded "Window" word, registered tm Microshifted, now I'll have to send them a royalties check.

IF you have a legit case, I'm wondering if you haven't left some speakers right up beside the case, and it may have become magnetized?

Do the colors shift, change, or "warble" like there is a motor running?

That could indicate some fan/transformer/power supply affecting it

Or does the affected area just "sit" there stationary?

That could indicate that the case itself might be magnetized.

It just sits there. There is a speaker to the right of my computer, which is about a half a foot to the right of my monitor. The color turns from blue, to a purple for the "my computer" window, and the start button appears to have the colors off. I can hold a speaker next to the monitor, and that does nothing, so I'm sure it's not that.

hmm, odd though, I run the sound out of my audigy into a splitter which feeds into my speakers, and a line to my stereo, and lately I've been noticing this hum through that line, but my speakers do not have it. I wonder if something is travelling through my case. And yes my case is a regular case, holes cut out where fan grills where, and some other mods, left side windowed, but it's the right side that is next to the monitor, and all in all, with all the crap inside, it's one bith heavy piece of steel.

Ok, I'd suspect a "stationary" magnetic field, as opposed to some electro-magnetic disturbance.

By that, I mean that because the distortion "just sits there" you may have caused an abnormality, such as (would) from your speaker magnet. I would try and move things temporarily, at least until you can determine for sure, even if you have to sit the computer, speakers, etc, in the middle of the floor. It MAY be that the case has become somewhat magnetised, say from a speaker.

If moving things don't clear it up, it may be either that the CRT has developed a problem, or that the degaussing coil in the CRT either isn't working, or that the magnetic disturbance is just too much for the onboard degaussing coils (in the monitor).

Try temporarily moving things around, if the problem persists, try turning the monitor on and off in a slow cycle. Some monitors, you can hear the "thoink" of the degaussing coil energize. If that does not work, try to find a commercial degaussing coil (for TV's) or a large Weller soldering GUN, or maybe a bulk video/audio tape eraser.


(I JUST don't know how you people come up with these problems!!)

You don't have some steel/iron/magnetic "stuff" UNDER the desktop, do you? Is it a metal desktop?

Actually, the desktop is wood, however just to the left where the computer and speaker reside on top is a steel filing cabinet...
