Tip & How-To about Computers & Internet
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.

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
