Turn On The PC And Nothing Happens

What is the first thing you will do after you plug your PC and found out that it has no lights, no beeps, no fan noise and no hard drive noise? Check your PC if it was plugged in! Let's say all connections are okay after you've double check, the first culprit here is the power connector. Check if the power connector is functioning. Also check for any rat or animal bite impressions on the connector, sometimes animal bite cuts wire connections. The second culprit here is the AVR or UPS; fuse maybe blown. The third culprit here is the Power Supply; you can find this on the back-top of the PC.



This is a very common problem, and most of the time, it has a very easy fix. Follow the below steps:

1. Power - Verify that the monitor has power and the power cord is firmly attached. Detailed instructions for accomplishing this task can be found above.
2. Video Cable - Double check that the video cable is connected to the computer. If the cable has become loose you may need to push it back in and tighten the screws that hold it in place.
3. Brightness & Contrast - Check the brightness and contrast controls on the monitor; It might have gotten bumped or changed accidentally. It may sound stupid, but this was one of the most common causes for people bringing their monitor in for repair when my friend work at a computer store. Most monitors have a button on them to reset all of the settings -- try pushing that.
4. Swap Parts - If possible, try swapping with another monitor that is known to work and vice-versa. If your monitor works on another computer, than the problem, most likely lies with your video card and/or motherboard. If your computer works with another monitor it might be time to invest in a new monitor.
5. Push In Video Card - Open up your machine and firmly push down on your video card so that you are sure that it is making contact with all of the contacts in the slot. If you computer was jumped and the screw that holds it down was not tight enough it could have come loose.
