check the power supply
you should start at the fuses or breakers. then check for voltage at the source. if you have voltage at the source, say ceiling fan. check voltage across the motor(voltage drop), . check for loose connections, loose grounds. check for opens in the circuit with power off from begging to end .check operation of switches physically and with meters. check for continuity (no opens) along the circuit with power off. these are just some of the basics for any circuit.
Troubleshooting is a process, not an event. Troubleshooting is the process of trying to identify the cause and solution to a problem, not a problem in itself.
An option that you have for computer hardware recycling is to first purge your hardware of any personal information. You can then donate the hardware to a charity for those that are less fortunate.
The problem could be as simple as a frayed wire (apex)

It is too expensive for you to make computer hardware. When you buy a cheap computer from a low cost company it is only possible because that company has imported the parts into your country and only put it together in the shop you buy it in. To get the same level of quality that others are getting from their computers means you will need to buy the computer hardware fully assembled by a trusted international company. They design it, they put it together, they test it to make sure it meets the standards their customers want and you get a computer that lasts for years

Test with a network cable
It is a hardware problem--check that it is plugged in!
I would take it back to the store and see what they can to as to fixing it. First check that is a software problem or a hardware problem then do the next step.software problem means reinstall the VGA drivers, hardware means change the part.
No you should not buy softwares before you buy your hardware because buying hardware first helps you decide what softwares will be compatible with your PC or notebook and then see which ones to buy.
Severely, severely, severely oversimplifying it... The hardware does the actual work, consuming power as it does it. The software tells the hardware what work to do, when to do it, and in what order it should be done.
You start by diagnosing the problem. There's more than one possible reason why this could malfunction, so you have to narrow that down first. Replacing the valve isn't going to help if the problem is in the ECM or the signal wire, after all.
The first step in resolving this problem will require isolating and diagnosing the problem(s) causing the misfires. These include the spark plugs, plug wires, ignition coils, and the ignition command module, among others.
First you should update your audio drivers. If this does not solve the problem you might have something wrong with the hardware in that specific computer.
patient's symptoms and medical history are the first steps in diagnosing an incisional hernia. All prior surgeries will be discussed. The doctor will ask how much pain the patient is experiencing, when it was first noticed, and how it has progressed

Have to be hardware. How could you write software if there were no hardware to write it on?
