I had the same problem when I reached in back of my pc and disconnected a web cam from a usb port. Them my monitor started shaking and i thought it was related to the web cam unplugging from the usb. I tried uninstalling my video card driver, and re-installing. Still no fix for the shake. So i tried turning off the monitor, and removing the monitor cable from the back of the pc. I re-attached the monitor cable, and powered on the monitor. Bam! No more shaking, all was good with monitor picture. The problem is, and was, as i unplugged the web cam usb plug from the usb port, i bumped into the monitor cable near where it plugs into the pc port. The problem is that there is a weak solder joint in the motherboard in the video card holder socket. I will need to either find the weak solder joint, and fix it, or replce the motherboard. I have a older dell antique dimension 8100 that i still like. It is the original motherboard and it is from 2002. I know i should replace this old pc, but i have done a lot of upgrades on it, and has been a great old pc. After shelling out over $2,000 for this unit in 2002, i want to keep running it. It does all i need to do. They don't build pc's this solid anymore. I hope this helps someone. Thank you!

I had the same problem and it was because my power board was sitting too close to my computer. Moving it up a shelf fixed the problem immedietly.

It may be due to shorted main filter capacitor, or due to disturbance any mobile or any other electronical gadget, so check it and place far to monitor.

Do you have anything sitting very close to the monitor which runs on mains power apart from your computer. I've seen this many times when my old apprentice put two monitors together almost touching. The screens shook like they were jelly. Unscreened speakers (mains powered) DVD players or virtually anything sitting close to the monitor which runs off mains power will cause it unless it's screened. Sometimes moving the offending item 6 inches away can stop the shakes. Other units may need more distance. If it's not that then you have a repair shop to visit. BMW

Just turn down the refresh rate.

Posted on Jun 03, 2008

Its probably the degaus causing what you describe as "shaking"

Posted on Feb 02, 2007

I experienced a similar problem on a Dell computer from which someone deleted the video card drivers. I found that by reducing the refresh rate under Display Properties, Settings Tab, Advanced button, corrected the problem.

When my pole saw is extended it is shaking really bad runs fine when it's not what could this be ?

I am assuming you have checked all screws are tight. Unfortunately a tiny shake in your hand ince travelled the distance of the saw will turn into a large shake by the time it gets to the end. Make sure your holding it correctly and if all else fails it could be a slightly bent bar which is very dangerous to use.

1995 Toyota Corolla Shakes at freeway Speeds?

You need to have your alignment, cambering diagnosed for you to know the real position of your four tires. yes you really need to check the tie rods.
Heating up the metal would most likely damage your paint and anti corrosion properties of your metal, try re-aligning the doors hinges by loosening the screws enough for the door to move, dont dismantle it.

There is a problem with the compatability of your tablet and your monitor. You either have to change your monitor to a different refresh rate or simply move your tablet abit further way from your monitor. If possible, you could change your tablet to "single mode" (depending on your tablet).
