One of two things usually.

  • Power supply
  • Motherboard


Start by unplugging the computer for about 15 seconds then plug it in and try to power up. If that doesn't work...
Purchase a new power supply, I'd recommend newegg.com, they are pretty cheap $15+. Search YouTube on how to replace, it's a fairly simple process.
If it still doesn't power up then you will need to replace the motherboard. There are videos for this on YouTube as well.

The most common reason a computer won't start can be a piece of hardware has failed or is causing a problem but that hardware isn't usually a hard drive, the part of your computer that stores all of your files. To fix such kinds of issue, you can take the following steps.1.create a bootable usb or cd ,there are kinds of software for you to complete this step, you can choose Fix Boot,EasyBootDisk or Windows Boot Genius. I suggest you to use Windows Boot Genius, it is easier and more effective.2.boot your computer from the created disk3.fix the issue after run the softwareBy the way, before any further steps you should make sure the power supply is good. Any hardware issues such as pc power and cable,motherboard corrupted should be troubleshooted.I don't suggest you to try the solution above until you are sure there is nothing to do with the hardware.

Free usb reboot


You might want to boot from a USB device, like an external hard drive or a flash drive, for many different reasons.
When you boot from a USB device, what you're actually doing is running your computer with the operating system that's installed on the USB device. When you start your computer normally, you're running with the operating system installed on your hard drive - Windows, Linux, etc.

How To Boot From a USB Device
Change the BIOS boot order so the USB device option is listed first. The BIOS is rarely setup this way by default.
If the USB boot option is not first in the boot order, your PC will start "normally" (i.e. boot from your hard drive) without even looking at any boot information that might be on your USB device.
Tip: The BIOS on most computers list the USB boot option as USB or Removable Devices but some confusingly list it as a Hard Drive option, so be sure to dig around if you're having trouble finding the right one to choose.
Note: After setting your USB device as the first boot device, your computer will check it for boot information each time your PC starts. Leaving your computer configured this way shouldn't cause problems unless you plan on leaving the bootable USB device attached all the time.
Attach the USB device to your computer via any available USB port.
Note: Creating a bootable flash drive or configuring an external hard drive as bootable is a task in itself. Chances are you made it to my instructions here because you know whatever USB device you have should be bootable after properly configuring BIOS.

  • Restart your computer.
  • Watch for a Press any key to boot from external device... message.
  • On some bootable devices, you may be prompted with a message to press a key before the computer will boot to the flash drive or other USB device.
  • If you do nothing, your computer will check for boot information on the next boot device in the list in BIOS (see Step 1) which will probably be your hard drive.
Note: Most of the time when trying to boot to a USB device there is no key-press prompt. The USB boot process usually starts immediately.

  • Your computer should now boot from the flash drive or USB based external hard drive.

Can't boot from flashdisk


USB thumb drives give you the ability to mobilize information, but they also have the power to act as a boot disk for both Windows and Mac computers. If you have a bootable thumb drive that you want to boot your computer from, you can easily set it up in the BIOS menu of your Windows computer or through the boot menu in Mac's OSX.

Plug your USB thumb drive into the computer. Boot the computer and follow the on-screen prompt to enter the BIOS (Basic Input/Output System) menu. You should "Press a certain key Usually the DEL or the F2 key to enter BIOS setup" or something similar when you turn your computer on. Follow the directions to enter the BIOS menu. Scroll over to the "Boot" menu in the BIOS screen. Change the primary boot device to USB port or something similar depending on your BIOS menu. Restart the computer with the USB thumb drive in the USB port. b> Mac b> Plug your USB drive into your Mac's USB port. Turn on the computer while holding down the "Option" button on your keyboard. Wait for the boot menu to appear with all of your bootable devices shown. Use the mouse to select your USB thumb drive from the boot menu. Wait for the computer to boot using your thumb drive. Hope this helps.

Computer is booting from a non-bootable source

Many times this error is caused when the computer is attempting to boot from a non-bootable floppy disk or CD-ROM. First verify that no floppy diskette or CD is in the computer, unless you are attempting to boot from a diskette.

Note: This error has also been known to occur when a memory stick is in a card reader and the computer is attempting to boot from it. If you have any card reader or flash reader make sure that no memory stick is inside the computer. Additionally disconnect all USB drives, cameras, ipods, iphones, etc. from the computer.

If you are attempting to boot from a floppy diskette and are receiving this error message it is likely that the diskette does not have all the necessary files or is corrupt.

If you are attempting to install Windows XP or Windows 2000 and are receiving this error message as the computer is booting verify that your computer BIOS has the proper boot settings. For example, if you are attempting to run the install from the CD-ROM make sure the CD-ROM is the first boot device, and not the hard disk drive.

Second, when the computer is booting you should receive the below prompt.

Press any key to boot from the CD

Important: When you see this message press any key such as the Enter key immediately, otherwise it will try booting from the hard drive and likely get the NTLDR error again.

Note: If you are not receiving the above message and your BIOS boot options are set properly it's also possible that your CD-ROM drive may not be booting from the CD-ROM properly. Verify the jumpers are set properly on the CD-ROM drive.

Computer hard disk drive is not properly setup in BIOS

Verify that your computer hard disk drive is properly setup in the CMOS setup. Improper settings can cause this error.

pauljohnchef.
If you want the computer to boot from the CD, you need to tell the computer to boot from the CD. At start up the computer runs through each device one at a time and tries to boot from it and it will boot from the first device that has a boot log. Right now your computer is set to boot from the hard drive before the CD drive.

Always back up your computer before going into the systems bios menu.

After a backup, upon starting the computer, press F12 when the bios selection appears shortly before the operating systems starts. Once in your bios menu, go to the boot order and tell your computer to first boot from the CD then your hard drive; then your disk drive if you have one.

After you are done, you can go back into the bios menu and change it back to booting from the hard drive first.
