Tip & How-To about Computers & Internet

You press the power button on your computer and nothing happens

1. Find out if computer has power.
Are fans running, lights on? When there are no signs of power, 99.9% of the time its a faulty power supply. Before you replace power supply try this.Unplug the power cord to the PC, wait approx 10 mins and plug back in. Does the computer power on now? If so, it may have been a power surge that the PC experienced. You may want to invest in an Uninterruptible Power Supply unit.
2.Computer is turning off by itself.
This can be a electrical short to a serious hardware issue. Open the computer case and inspect the wiring. Make sure there is no chafing or exposed direct contact with metal. Look for loose connectors. Connectors can become unseated. Inspect and reseat all connections.
3.Computer beeps shortly after powering on.
The beeps are error codes and can be used to troubleshoot computer search google for number of beeps
4. PC powers on and display codes.
POST (Power On Self Test) codes, are usually specific to the manufacturer. It’s best to go to manufacturer support website the codes can point you in the right direction. If you get “No hard drive connected” error, reset the connectors on the hard drive and test again.
5. Computer turns on but the operating system wont load completely.
Boot up in safe mode by pressing F8 during boot up, select safe mode with networking and after everything loads, boot back up in normal mode. If you installed any recent drivers you can uninstall them and see if that helps if this is not helpful most of the time you will have to use a restore disk and put computer back to factory settings.

t5020 emachine seems to have dead power supply- how can I confirm?


If the PSU fans only work for a short time usually this means that the PSU is shot

If you suspect your power supply has gone bad, there are a few basic things you can do to test it. First, plug the computer in and try to start up the computer. If the computer can start up or shows signs of having power (the hard drives spin up, or the fans turn on) the power supply might be fine, and you may have an issue with your motherboard or RAM. If the computer won't start at all, open the case and then turn the power supply on and attempt to start the computer. Observe the motherboard to see if any lights turn. If no lights turn on and there is no sign that power is being supplied to any of your devices, there's a decent chance that the power supply has burned out. If your computer experiences periodic crashing, feel the case near the power supply to see if it is hotter than normal, and smell the air. If the case is much hotter than normal or you smell burning, your power supply might be overheating, and may be damaged. http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm hope this helps

no power only orange power light


Hi, It most likely is a faulty power supply or a motherboard issue. Remove the power cord then press and hold the power button for at least 30 seconds. Then plug it back in and hit the power button. This will release any static buildup that might be in the computer and sometimes that causes it not to boot. If nothing is happening it is more likely your power supply than the motherboard.

Nothing happens when ON button is pressed, only green light on power supply is on. The fan is not running either. Preceeding this event, computer will run only whe I kept ON button for several seconds.


Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical extension or fan lead can cause this problem hope this helps

Can you hear the Power supply fan running in the back of the computer? Usually, these symptoms indicate a faulty power supply to the motherboard. When was the last time the fan was cleaned?
