NT Computer Repair works around the Twin Cities. Im located on the East Side of St. Paul. I fix computers and build computers. Thease are one of the main intrest i have, So let me work on your computer!
1) Take a look at he back of the computer and see if it is plugged in. If so then take a look at were its plugged in and make sure their is power running threw it.
2) Turn it on. Press the power button. (People think that the computer comes on right when you plugge it in, It dont)
3) Check the Monitor. Sometimes the pluggin for the moitor comes un-done so you need to put it back in. And also check the power cord. See if it is also plugged in. (Your computer may be running and you may not know it becuse the monitor is not working.)
4) If none of those tips work, the bring it to a computer tech. Because it is somthing with the inside of your computer. And working on the inside of your computer with no computer working experinces can be bad on you and your computer.
