I placed my Camera's card placed In Computer and all the colors went wild, removed Card, now everthing on my screen shows mixed colorsrd


I had something similar happen to ma about a year ago, I moved my tower a couple inches to reach for something that fell and then my screen was "colorful". Turned out that I just knocked my monitors cable out just enough that it was not working properly. I would first check to see if either end of the monitor cable has come loose from the computer tower or the monitor itself.
I have also had the colors go wild when I had a faulty video graphics card, but I would start with the cable first to make sure it is secure.

It means that your monitor is not getting a signal from your PC. Your monitor is fine though. You will need to plug the video cable from your monitor into the onboard video if you are using a graphics card. If you are not using a graphics card then you will probebly need to get a PC technition to diagnose the problem with your motherboard.

Wiring code for ceiling fan


These fans do not have a standard color code for the fan switch. What you can do is turn off the power, keep the white neutral connected. Then using the black power wire take one of the switch wires and connect to that black, turn the power on and observe the speed .. low mark it 1, medium mark it 2, high mark it 3. Repeat untill you have identified all the speed wires. Then connect these wires to the 1,2,3, terminations of your new switch

I would guess that the black wire on the timer is the power in and blue is the power out to the fan (hook it to the black wire going to the fan) The other colors are right.
