This computer is driving me crazy. Today I added in a PCIe modem card (don't ask) and after turning it back on, it's not acting right. Firstly, the obnoxious vibrating noise that was coming from the top of the computer is gone, but the entire computer is vibrating, but it's not's loud. You wouldn't notice unless you touch it. But I can sometimes feel it on the desk where the keyboard and mouse sit. The computer is slightly louder than usual, but the average person might not notice it. I do.
The the sensation I'm feeling when I touch the computer is more like an electric current than a vibration. It's weird. If you've ever touched an electric fence, it feels similar to that. I don't think it's electricity though. Since I feel this sensation through the wood desk it has to be a vibration, right?
I turned it off and took the cover off, but didn't see anything obvious. There's not really any dust in there. I've only had it since January.
Any ideas on what could be going on and is this vibrating potentially a problem?
The computer is a Lenovo 710-25ISH Desktop (ideacentre).
