How to Troubleshoot a Computer That Won't Start

Instructions Things You'll Need:

  • A Startup Disk Or A CDROM With The Operating System On It
  1. If your desktop computer does nothing at all when you try to start it, first check that the power cable is securely plugged in at the back of the computer as well as into a working power outlet. It's amazing how often this is the case.
  2. If you're starting from a button on the keyboard, make sure the keyboard is connected to the computer.
  3. If the computer is plugged into a surge protector, see if the surge protector has a reset switch that you can push. (If it doesn't have a reset switch and the problem is with the surge protector, it will need to be replaced.) Try plugging a lamp or other device into one of the surge protector's outlets to make sure it's working.
  4. If you can hear the computer's fan or hard-disk drive, or if you can see indicator lights on the main unit but the monitor stays dark, make sure that the monitor is connected to a working power source, that it's turned on and that it's securely connected to the computer via the video cable.
  5. If the monitor and computer have power but the computer displays a "Non-system disk or disk error" message, check to make sure you didn't leave a disk in the A: drive. If you did, eject it and restart the computer.
  6. If the operating system still won't start even though the computer and monitor have power, try restarting with a Windows CD-ROM in the CD-ROM drive or, if you've got a Macintosh, with a Mac OS disc in the CD-ROM drive. (You can start a Mac from the CDROM drive by holding down the C key while starting up.)
  7. If the operating system then starts, your problem is probably with the startup hard drive or with the operating system installed on it. If you can't fix the drive, you'll have to replace it.

I need to know if i can recover the Operating System on my Sony laptop it has a OEM harddrive I lost the Operating System by Mistake can i recover the Operating System Through the BIO"S or dose it need a new one My Operating System is Vista Pre The Model number is VGN NS130E


How did you lose the operating by mistake? Did you format the drive?
You can not recover the operating system from the bios. But you may have a choice when the computer boots up there may be a recovery option, you can try that. If not you would have to reinstall or try a repair from a vista disk if you can borrow one from someone. Please let me know if I can offer any other help, Thanks for using FixYa

when i turn on my Acer Aspire One D255 it says: "check cable connection! PXE-M0F: Exiting Intel PXE ROM. No bootable device -- insert boot disk and press any key"


The PXE ROM is part of your system's network interface controller. It is being entered on your system's startup to look for a bootable image on a physical network connection and if found, to boot from that image. If there is no network cable connection to your system or if there is but no bootable device is found on that connection, the result is the error message that you got. As to why your system is entering the PXE ROM can be explained by looking at your system's Setup Utility,,,

Press F2 while powering up to enter the Setup Utility and use the cursor control keys to go to the Boot tab which then shows the Boot priority order. The default order is as follows...
1. IDE0
2. IDE1
3. USB FDD
4. USB HDD
5. Network Boot : LEGACY PCI DEVICE
6. USB CDROM
Your system's internal hard disk drive should be listed beside IDE0 and it will be accessed first to look for a boot record. If the drive fails to boot, the next devices in the list will be accessed accordingly until either a bootable device is found or the last item which is USB CDROM. If a USB CDROM is plugged in on one of the system's USB ports, it will be checked for a bootable record and if not found or no CDROM is plugged in, then the system displays the last part of the message -- insert boot disk and press any key.

Press F12 while powering up enters the Boot Menu which has the Boot Option Menu. This menu should show by default the following...
1. IDE 0: (the name/type information for your system's internal hard disk drive
2. Network Boot: LEGACY PCI DEVICE

If there is no hard disk drive information shown beside IDE 0, then the possibilities are that
1. there is no internal hard drive present
2. there is a hard drive but it has failed
If there is hard disk drive information and pressing enter to select it does not result in an operating system startup, then the drive's startup partition has been wiped and so it has no bootable image.

If there seems to be an internal hard drive present but it has no bootable image, you may attempt recovery from the installation images in the hidden partition. The recovery allows restoration of...
1. operating system to factory defaults
2. applications (selectable)
3. drivers (selectable)

Press Alt and F10 keys together while powering up and the Acer logo is showing to enter Acer's eRecovery Management. Follow the instructions to do the recovery.
