when my mini fridge powers to up to change temperature. My computer at the exact same time makes this disconnect noise, like I'm removing a device. Why is this? Also my pc would randomly reboot like someone is holding down the reset button, but I figured it was from new ram I installed. But now that plugged out the mini fridge my pc is working perfect again... Also when the mini fridge was plugged out my led lights on my speakers started working again. why?
 
Solution
Refrigerators generally draw lots of current ESPECIALLY when they first come on.

This causes a big surge of current and a corresponding voltage drop.

I think this voltage drop is what is causing your problems.

In a case like this, if you must have the mini fridge you should probably get a UPS/line conditioner to hook your computer to. Would likely be more desirable to put the fridge on another circuit but that is likely a whole other room.
