The reason why the computer can not open machine and the solution

Whether it's a laptop or a computer, there are times when computers don't open machines. After a period of time to review the following discussion may be helpful to you ~ ~ Boot into the BIOS may be the BIOS battery is running out of power, if yes, replace the BIOS battery.





If you do not restore the BIOS to factory settings, you can also try to discharge the BIOS battery.





if not, fix the system.





1, Boot press F8 does not move to the advanced option appears in the Let go, select the last Known Good Configuration carriage return repair.





2, please turn on the F8 into Safe mode with the system from the System Restore, restore to you do not appear when the failure to repair.





3, if the failure is still, use system disk repair, open a command prompt input Sfc/scannow return (SFC and/between a space), insert the original system disk repair system, the system will be automatically compared to repair.





4, if the failure is still, set the optical drive in the BIOS to insert the system installation disk for the first boot device and press R to select "Repair Installation".





5, if the failure is still, it is recommended to reload the operating system.





if not, it is recommended to choose a repair installation, so that the system is repaired, but also to the C-disk program and documents are not subject to loss.





computer startup Occurs when a panic failure, can be divided into post is a panic and load the operating system occurs when the crash two. For the computer self-test, the specific maintenance method for the crash is as follows.





(1) First to determine the situation before the computer failure, if the computer is in the move after the crash, may be the computer in the mobile process by a great shock, resulting in the internal parts of the computer loose and poor contact caused by the crash. Open the chassis to the memory, graphics and other devices to tighten it.





(2) If the computer is in the process of upgrading the BIOS after the crash failed to start, it is possible that the BIOS program upgrade failed or upgraded BIOS program files and computer hardware is incompatible with the original BIOS program files can be restored.





(3) If the computer is in the setup of the BIOS program after the crash failed to start, the set of BIOS settings are modified back or the BIOS program in the "Load BIOS DEFAULTS (Load standard preset)" option to restore the BIOS program.





(4) If the computer is in the CPU overclocking or upgrade after the crash can not start, may be due to CPU overclocking or upgrade caused by the computer panic, the CPU frequency back to normal frequency or restore to the state before the upgrade.





(5) If the monitor screen prompts "Keyboard error (keyboard error)" or "Hard disk install failure (hard drive installation failure)" When the power-on starts, the related equipment is not connected or damaged, reconnect or replace the faulty device.





(6) If the ScreenTip "Disk Boot failure (invalid boot disk)" is missing or corrupted system files, or the hard disk partition table is damaged, repair system files or restore the hard disk partition table.





(7) If not the above problem, then check the chassis is clean, because the dust corrosion computer circuit and interface will cause poor contact between equipment, causing panic, so clean dust and equipment interface, the dust caused by the failure can be ruled out.





(8) If the failure is not excluded, the final use of the replacement method to eliminate the compatibility of hardware equipment and quality problems.





for computer loading operating system when the panic failure of the repair method is as follows.




The
(1) is judged first according to the error message displayed. If the system file is not found when you start up, the system files may be missing or corrupted. Maintenance can be from the other computer in the same operating system to copy the missing files to the failed computer (some system files are not universal).





(2) If a blue screen appears at startup, prompting the system file to locate the specified file, the hard drive fails to cause the computer to read the system files. Start the computer with the boot disk, run the "Scandisk" disk scanner, detect and repair the hard drive bad way.





(3) If there is no such fault, first use anti-virus software to kill the virus, and then use "Safe Mode" to start the computer. If it does not start, it is likely that the system files will be corrupted and the operating system reinstalled.





(4) If you use "Safe Mode" to start the computer, and then quit the reboot system to see if the crash.





(5) If you still panic, then use the backup Windows registry to restore the system (if the system does not start, then use the boot disk), after recovery to see whether normal.





(6) If it still freezes, then enter "Safe Mode", open the Start/Run dialog box, enter SFC and press ENTER, start the System File Checker, start the detection system, such as detect errors, the screen prompts the name and path of the specific damage file, and then insert the system CD, select "Restore Files" command, files that are lost or lost will be restored.





(7) Finally, if the system still freezes, reinstall the operating system.





the BIOS battery discharge (Restore BIOS factory defaults) is recommended to plug the video card, memory, clean the health, and polished video card, memory gold fingers.





Unable to start the operating system the various diagnostic methods are as follows.





first checks to see if the computer has started the operating system when it is powered on. If a panic, blue screen, or automatic reboot occurs when the operating system is started, the partition table for the hard disk and the master boot Record are normal, troubleshooting the hard disk partition table corruption, the hard drive master boot record, and the missing hard disk partition end sign. The following method is then used to diagnose.





The 1th step: Start the computer in Safe mode first, to see if it can start, if it does not start, it may be infected, System file loss, operating system damage, hard drive, hardware device conflicts or hardware problems, go to step 4th; If you can start Safe mode, it may be that the hardware driver is incompatible with the system, The operating system is problematic or infected with the virus.





2nd Step: Then run antivirus software, if there is a virus, it may be caused by virus, anti-virus after restart the computer, if not normal, you need to reinstall the operating system.





3rd Step: If the virus is not detected, you can use the operating system with the "System Restore" function, the System Restore, restore if the system is normal, the fault is caused by system damage. If the failure is still the case, the device driver may be incompatible with the system; then the sound card, video card, Nic and other devices to remove the driver, and then install the driver, each installation of a device to restart the computer to check which device driver caused by the fault, check out, Download the new driver for the faulty device and install it.





Step 4th: If you cannot start in Safe mode, then reinstall the operating system with the installation CD. If you can install the operating system normally, go 7 steps, if the operating system failure, such as the crash, blue screen, reboot, etc. caused the system can not be installed, it should be a hardware problem or bad hardware contact caused.





5th step: Then clean the dust in the computer, cleaning memory, graphics and other equipment, such as gold fingers, reinstall memory and other equipment, and then reinstall the operating system, if the normal installation of systems, it is bad contact caused by the failure.





Step 6th: If you still cannot install the system, it may be a hardware problem caused by the failure. Then use the replacement method to check the hardware failure, after the replacement of hardware can be found.





7th: If the operating system can be installed properly and the failure disappears after installation, it is a failure caused by system file corruption.





8th: If the installation of the operating system, the failure is still, it may be the hard drive has bad road or device driver and system incompatible and so caused. Use Safe mode to start the computer, if it can not start, it is hard drive has bad cause of the fault. Then use the NDD disk tool to repair the bad way.





Step 9th: If you can start Safe mode, the device driver is incompatible with the system. Then the sound card, video card, network card and other devices to remove, and then install the driver one after another, to install a start, to check which device driver caused by the fault. After checking out, download the new driver for the faulty device and install it.
