Computer crashes, blue screens, black screen, error resolution

1.ctrl+alt+delete, open Task Manager, select shutdown - reboot, if not, then look.

2. press and hold the power supply for 5 seconds, force the shutdown, (because the CPU may be overheating, it needs to cool down), in the normal boot, if not continue to look.

3. Long Press Power 5 seconds, Force shutdown, Power on, press F8, select the last normal start, if not continue to look.

4. Long Press Power 5 seconds, Force shutdown, Power on, press F8, choose to enter Safe mode, if not continue to look.

5. If the computer is good, then in the restart, make sure that the computer is completely good, in the safe mode of overall anti-virus, if not open again, then look.

6. If none of the above methods, prepare the system installation disk, GOST a bit.

7. Prepare the Office software reload, and then restart a few times to try the computer, if not, then look down.

8. prepare the mobile hard disk and format and partition software, backup the important files, and re-partition the computer after formatting.

9. after reformatting, first install an anti-virus software, reboot into Safe mode antivirus (because some viruses can only be killed in safe mode).

Put the mobile hard drive also plugged in, in the overall anti-virus, if not yet, then look.

find a screwdriver, buy a computer cleaning kit open the computer back cover, key out the memory to sweep the dust, remove the CPU sweep dust, and then installed.

Restart the computer, enter Safe Mode or start the test normally, if there is no problem, prove the computer is OK.

If it doesn't work, prove that your computer does have a bad hardware.

BB is the sound of the alarm, you can according to the alarm sound length , the number to determine where the problem is!

The general meaning of the award BIOS Ring Ring is:

1 Short : The system starts normally. This is what we hear every day, and it shows that there are no problems with the machine.

2 Short : general error, please go to CMOS setupand reset the incorrect option.

1 Long 1 short : Error in RAM or motherboard. To change a memory try, if still not, had to replace the motherboard.

1 Long 2 short : incorrect display or display card.

1 Long 3 short : keyboard controller error. Check the motherboard.

1 Long 9 short : motherboard Flash RAM or EPROM error,BIOS corrupted. Try swapping Flash RAM .

constant Ringing (long sound): The memory strip is not plugged in or damaged. Reseat the memory bar, if not, only replace one memory.

Keep ringing : power, monitor is not connected to the display card. Check all the plugs.

repeat short ring : Power issue.

No sound no display : power supply issue.

The general meaning of the AMI bios ring tone is:

1. A short sound, memory refresh failed. Memory corruption is more serious, I am afraid to replace the memory is not.

2. Two short sound, memory parity error. You can enter the CMOS settings to turn off the memory Parity parity option, which is set to Disabled. However, in general, the memory bar has parity and open parity in the CMOS settings, which is good for the stability of the microcomputer system.

3. three short sound, System basic memory ( 1 64Kb ) check failed. Replace the memory.

4. Four short sound, system clock error. Repair or replace the motherboard.

5. Five short sound,CPU error. But not all of the CPU itself is wrong, it may be the CPU socket or something else, if this CPU is normal on the other motherboard, then the motherboard is definitely wrong.

6. Six short sound, keyboard controller error. If the keyboard is not plugged in, it is good to do, plug on the line; If the keyboard is connected properly but there is an error, you may want to try a good keyboard, otherwise the keyboard control chip or related parts have problems.

7. Seven short sound, system real mode error, cannot switch to protected mode. This also belongs to the motherboard's fault.

8. Eight short sound, memory read / write error. The memory chip on the video card may be damaged. If the memory chip is pluggable, simply locate the bad piece and replace it, otherwise the video card needs to be repaired or replaced.

9. Nine short sound,ROM BIOS check error. Replace the same type of good bios try, if it proves that there is a problem with the BIOS, you can use the rewrite or even hot plug method to try to recover.

10 short sound, register read / write error. Only repair or replace the motherboard.

One. 11 short sound, cache error.

If you do not hear the beep ring Bell can not see the screen display, first should check if the power supply is connected, in the overhaul is often easy to neglect, do not connect the motherboard power on the boot test. The second thing to see is not what parts are inserted, such as CPU, memory, etc. Again, unplug all the cards in question, just leave the display card to try. Finally, locate the jumper on the motherboard to clear the CMOS settings, clear the CMOS settings, and let the BIOS return to the factory state. If there is no problem with the monitor or the display card and the connection, the CPU and the memory also have no problem, after these steps, the microcomputer is still not showing or ringing the ringtone when the boot, that can only be the motherboard problem.
