Hey everyone.. I finally installed the watercooling system in my comp and it seems to be running fine. However, the picture on my monitor is shaking... what i mean is is that the sides of the picture are moving up and down really fast( if you deguass your monitor, it should have the same visual effect i've just described).... The shaking is very minute but it's still there...I've tried degaussing but that doesn't seem to work... I don't know wehre the problem is but i think it could be because i have the radiator fan next to the monitor cord... I've tried unplugging the fan but the screen still shakes... any ideas?

You sure it isn't just classic moire? If the lines are curved then it probably is. You might be able to use your monitor's on screen display to adjust the moire. It could also be that your monitor cable is not plugged in correctly or has something blocking the connection to your computer or to the monitor. If you have a low quality monitor cable it might be good to replace it anyway, for use with future monitors. I would also remove and check both ends of the monitor cable to make sure there are no foreign materials blocking the connection. If you think that there's interference from other cables (the fans won't provide any interference by the way) then cross your cables at a 90 degree angle. This minimizes the chance that they could electromagnetically affect each other. If your cables run parallel to each other then it could be affecting your monitor's display. Speaker cables are notorious for causing the most interference, so check the cables attached to your sound card and make sure they aren't interfering. Finally check the orientation of your monitor. What angle was it facing before you installed the water cooling system? The earth has a magnetic pull and also pay attention to true magnetic north in NW Canada. Simply by rotating your monitor you can subject it to changing magnetic conditions.

A Fan blowing air at a monitor can sometimes cause this problem, if you have high airflow directly at your monitor, try doing without it. The other option is electromagnetic interference. You didnt by any chance set your monitor on your subwoofer did you? etc etc...

I do have my subwoofer by the monitor but it hasn't affected it before... I think it is electromagnetic interference because when i pull the plug on the watercooler, the vibrating stops. I'm just wondering why the pump creates any emi at all... I think it's affecting my video card, but it could be that my monitor is too close to my system...

I'll also check my cable placement...

I'd probably go step by step then and eliminate possibilities one by one. The first thing I could think of it irregularities in your power supply caused by plugging in your water cooler into it. Open up motherboard monitor and set it to log the power supply's output, and go play a demanding 3d game for a little bit. Then check the logs. If the power varies a lot then it could be the power supply.

Then you might want to make sure your power socket itself isn't overloaded. Are too many things plugged into it? Try to plug things into different sockets to make sure your computer gets 100% of the power.

As for fans causing monitor interference I didn't know about that. I'll have to watch for that in the future.

metal moving against metal can create emi. I get this with Radio Control aviation alot. Engine's can create interference with the radio so you have to shield against it.

There is also the issue with CAS-3 RAM. It can also generate interference between itself and the processor and i suspect would be more susceptible to interference from a pump as well.

Bottom line, could be a defective water pump who's motor is rubbing somewhere inside creating interference.

PS. Most subwoofers have a warning on them saying to keep at least 3 ft from the monitor, as in preferably below the desk on the floor. Placing that next to the monitor definitely wouldnt help the situation-)

btw, when you unplug the water cooler...wouldnt you be like frying your processor=)

Hope my thoughts help you somehow. this is about as much as i know.
