Computer won’t boot

Computer-won't-boot

We will repair any problems but first try troubleshooting your Computer:

Computer beeps irregularly when the computer is turned on.
Computer turns on but does not boot or do anything.
Computer reboots every few seconds.

Make sure the computer turns on, if nothing happens, no lights, no sound, no fans. The computer has a power related issue. No power from the computer can be caused by any of the below possibilities.

Connections not connected properly.
Third-party hardware.
Bad power cable.
Incorrect power supply.
Bad battery.
Bad power supply, power button, or power board or inverter.

Solutions if computer won’t boot

Remove new hardware:

If any new hardware has been recently added to the computer, remove that hardware to make sure it is not the cause of your issue. If after removing the new hardware your computer works it’s likely the computer is either not compatible with the new hardware or a system setting needs to be changed to work with the new hardware device.

Remove any disks or USB devices:

Remove any disks, CD’s, DVD’s that are in the computer and if any USB devices, iPods, iPhone, drives, phones, are connected disconnect all of them as well. Reboot the computer and see if anything changes.

Disconnect external devices

Remove everything from the back of the computer except the power cable. Turn on the computer and see if it beeps normally. If the computer has never beeped keep the monitor or display connected to see if any change occurs.

Identify beep code

If you are receiving a sequence of beeps see the beep code page for a listing of different beep codes and their explanation or your motherboard or computer documentation. These beep codes are meant to help identify what computer component is failing or bad. If your beep code is not listed, continue troubleshooting.

Check all fans

Make sure all fans are running in the computer. If a fan has failed (especially the heat sink fan for the CPU) your computer could be overheating or detecting the fan failure causing the computer not to boot.

Check all cables

Verify that all the cables are properly connected at that there are no loose cables by firmly pressing in each cable. All disk drives should have a data cable and power cable connected to them. Your power supply should have at least one cable going to the motherboard. Many motherboards may also have additional cables connected to them to supply power to the fans.

Disconnect all expansion cards

If the above recommendations still have not resolved the irregular POST, disconnect the riser board if applicable and each of the expansion cards. If this resolves the issue or allows the computer to POST connect one card at a time until you determine what card is causing the issue.
