My computer is old and dead, broken, black screen blue screen, what to do

Hello! Please ask if your operating system is pirated! If yes, I recommend you install the operating system from you!

To facilitate the optimization of crashes and other problems!

Clean up the CPU heatsink. The gold finger of the memory is wiped with an eraser.

What is the blue screen** sent up.

Hello, the situation you said is generally caused by system software, memory, and hard disk.

1 If the computer is unintentionally loaded with malware, or malicious programs are generated when surfing the Internet, it is recommended to use 360 Guard, Kingsoft Guardian and other software to clean up the garbage and kill the malware, which may be solved.

2 Recently, the computer has been poisoned, unstable software has been installed, etc., it is recommended to take a full antivirus, uninstall the software that caused the problem, and reinstall another version, which may be solved. No more, it's OK to reinstall the system

3 If the computer has been used for a long time, dust has entered the case, disassemble the case, remove the memory module, clean it, and then install it back. It may be solved.

4. If the memory of the computer is bad for a long time, the parallel memory is bought, and the multiple memories are incompatible with each other, it is recommended to replace the memory.

5 The computer has been used for a long time, the hard disk is broken, and the logical bad sectors can be repaired by repartitioning and installing the system, but it still doesn't work, then it's time to change the hard disk, and it can be solved by changing the hard disk.

If you are not professional, it is recommended to take it to a computer store to test, and then change it after the test is good.

Hope it helps!!

I don't understand hi me, I can teach you to analyze and solve it slowly step by step...

It's just a very common file loss. Every time I turn on the computer for more than 2 hours, it is obvious that it is a problem with the hard disk. You can check it with the tools in the capital.

If there is a bad sector, you can try to fix it.,If you can't fix it, just cross out the part of the disk with a bad sector.。。

Black screen directly after boot:

First of all, see if your monitor power is on, and if so, see if your monitor switch is on;

Secondly, look at whether your host power indicator is on, if it is not lit, consider that your power supply may be broken, if it is bright, listen to the sound of the host after powering on, if it is very crisp 'tick' and the power supply, CPU, and graphics card fans are turned to the phone, then you have to consider whether your graphics card is out of the question, if it is a continuous 'tick tick' sound, see if the gold finger of your graphics card and memory is not in good contact due to oxidation, polish them and reinstall them, and then turn them on;

If the screen is still black, then you have to look at your CPU and its power supply module, see if the capacitors around the CPU are bursting, smell if there is a smell of burning, if there is a smell, it means that the hardware is damaged, take it to the computer store for repair.

Win7 boots up with a black screen, but you can see the mouse.

1.At the same time, press the keyboard Ctrl+Alt+Del (of course, before this step, first make sure that the computer is connected to the keyboard), select "Start Task Manager" in the list, this will pop up "Task Manager", click the upper left menu "File" - "New Task" with the mouse, enter "Explorer" in the pop-up "Create New Task" dialog box and click "OK", this is the desktop of the system is displayed normally, which completes the first step, and completely solves it according to the steps below.

2.Click the "Start" button in the lower left corner of the screen, enter "regedit" in the text box, and press Enter to enter the registry, as shown below

Registry Options:

hkey local machine software\microsoft windows nt\currentversion winlogon,(click on the corresponding item with the mouse, that is, pull down its child, and find the corresponding item in the child.)

to find the winlogon item in order).

Find the winlogon item, click it with the mouse, find the "shell" item in the list on the right side of the screen, right-click it, select "Modify" in the drop-down menu, delete the content behind the "digital data" in the pop-up "String" dialog box, click OK, and close the registry, so far, the problem should be completely solved, in addition, the problem is caused by a virus, please check the computer for viruses.

If this solution does not solve the problem, there is no other better way, it is recommended to reinstall the system.

General causes.

A software conflict, you can think about what you are running when it will arise...

2. Software problems, system junk, malicious plug-ins, viruses, etc., 4. Hardware incompatibility or poor contact.

It should be a system issue. It's best to reinstall if you can. After reloading, it's still useless, so I can only find someone to fix it.

Oh yes, back up important files before reinstalling.

There are software remnants registry information,And useless xx components,360 clear,Or use win7 optimization master clear,I feel that the second cleanup is clean,Because it's slow.。 There is also to ensure that the C disk space is large enough, in addition to the commonly used input methods, it is best not to install C disk in other software!

There is a final declash to be done.

If you change it, the machine may be too old.

If the memory card is loose or broken, you can replace it.
