Picture Shakes

[kcp1375]

I had to replace my power supply on my desktop recently (from 250 to 400), and, as soon as I did, both of my monitor's pictures started shaking, with waves. Nothing else has changed. No magnetic fields, no other new devices, etc. The refresh rates are already at 60. The only thing that gets them to stop shaking is to set the resolutions at 800 X 600 or less, which is awful. I even plugged the monitors in to an extension cord run two floors away - no change. Anyone have any thoughts as to what might be wrong?

Are the two monitors interfering with each other?

Try moving them apart.

Thanks for the reply. I tried moving the monitors apart, but no change. I even unplugged them one at a time (using only one), and whichever monitor I kept on still has the problem. Any other suggestions? Thanks

I'd borrow a power supply and test since you said the problem started when you installed the new one.

Beyond that look for anything that could cause an electrical field. These include electric heating, florescent lighting, powerful electrical motors, AC fans, audio amplifiers, power tranformers (AC adapters for small appliances).

One other thing, make sure your monitor cables don't run side by side with each other nor with power cables.

That's about all that I can think of.

I checked everything else as best I could, with no luck so I'll try another power supply just in case. Thanks again for your help.

Before you buy another power supply and as a last resort, I'd take the computer and one monitor and move them to another room of the house. If the problem goes away then something in the old room is definitely causing the interference.
