How to solve the problem that the computer has a black screen when it is turned on for a long time b

Let me tell you first.

It's not a problem with your machine.

Many people have this kind of problem with their computers.

It's not a matter of the configuration of the machine itself, follow the following method.

It should be no problem1、Adjust the screen resolution to the resolution of the current desktop,If your book is1024x768, adjust it to1024x768,Mine is1280x800;

2. Tick off the "hardware pointer" is not enabled;

3. Tick off the "window mode" and do not enable the window mode (whether it is the maximized window mode or the original window mode, it is not enabled!) )

4. Tick off "Use UI Scaling" and don't enable it;

5. Since the graphics card for 9200 is not very good for World of Warcraft, so in order to save resources, adjust the "world appearance", but adjust the "spell details" to medium and upper, the reason is very simple, adjust the ice ring too low, and the dedication can not be seen clearly! , "Special Effects" and "Others" are not enabled!

6. When you don't read the progress bar, you can restore the above options appropriately, especially the "hardware pointer - correction delay" is best opened, otherwise the mouse will be meaty, I can't describe it, just try it.

Black Screen Issue: Hope it helps:

There are many reasons why a computer has a black screen, and the common ones are:

Shows poor contact of the data cable;

There is no power supply to the motherboard;

Poor graphics card contact or;

Poor CPU contact and overheating;

Poor contact of memory modules;

poor power performance;

Machine infection. cih

Viruses, BIOS

is destructively refreshed.

Microsoft black screen, please patch.

Most of these problems are the relationship between the memory and the graphics card, loose or poor contact, just move it or use the eraser to wipe the gold finger of the interface

Clean up startup items:

Method 1 [Secret 1] 、

1. Press and hold the Microsoft logo key on the keyboard at the same time, press the R key, and the "Run" interface will pop up, enter "msconfig" and click OK;

2. After entering the interface of "System Configuration", select the "Startup" tab, cancel the check mark in front of the software that does not need to be booted, and then click OK;

Method. 2. Use PC Manager to clean up startup items.

1. Click "Startup Items".

2. Disable unnecessary startup items.

Secret 1] aaa

This is caused by leakage of the visor header and the header must be replaced. When the back cover is removed, you can see a small circuit board at the end of the picture tube, and the tube socket is soldered to the circuit board. Carefully unplug the board, solder the header, go to the electronics store and buy the same header, and solder the header back to the board.

At this time, do not rush to put the circuit board back, first find a small piece of sandpaper, and carefully wipe the pins protruding from the end of the picture tube with sandpaper. In particular, pay attention to the oxide layer on the pins, if you don't wipe it cleanly, it will soon become old**. Put the board back in and you're done.

Secondly: After the display is turned on, it takes a long time to light up to prove that the display hardware is faulty, and its circuits and components should be specifically investigated

1) Check whether the filter capacitor at the output end of the power supply is damaged, if it is bulging, replace this capacitor.

2) Use a multimeter to measure the 12V resistance to ground on the main board of the monitor and confirm its value.

3) Check whether the filter capacitor at the 12V output is bulging or bursting...

It is also possible that the computer is aging and stuck.

Questions. The notebook is uniformly configured by the unit, and it doesn't take long to send it, and other colleagues' are still easy to use.

Could this also be an aging issue?

This problem only occurs after the computer has been upgraded.

It turns out that it has always worked well.

That's because of the Fast Boot system, which allows your computer to be up and running as soon as it is turned on.

Therefore, the screen will be extended accordingly.

Questions. After booting up, there will be a normal startup and login interface soon.

However, then the screen starts to go black and it doesn't go to the desktop until much later (at least 3 minutes).

So I'll try to tick "Quick Startup" on?

You can tick the box to try.

If it still doesn't work as expected.

It is recommended that you contact the after-sales service for maintenance, and the internal components should be damaged.

Questions. Good. Thank you!

Duty, you're welcome.

2. Double-click to open the newly created [Text Document], and copy and paste the following paragraph of text into the [Text Document Min Zhao Gaze].

enableulps"=dword:00000000

enableulps"=dword:00000000

3. After pasting all the text, click [File] in the upper left and select [Save As] in the subordinate menu bar.

4. Select [Text Document] to exist on [Desktop], and then name the file as [Fix Black Screen at Boot]. reg], then change the Save Type to All Files, and finally click Save.

6. Then a [Registry] window will pop up, and then click the option [Yes] to complete the repair of the black screen at boot.

The above is the way to solve the problem of win10 computer boot black screen for a long time before entering the desktop,Netizens who have the same problem can follow the above methods to solve it。

Win7 system boot black screen for a long time to enter the desktop, the possible causes and solutions are as follows:

1. Hardware problems:

1) Insufficient memory: If the entry speed was not slow before, now it is slow, and there are two memory, it may be that a memory is faulty, check whether the memory capacity is consistent with the original configuration after entering the system, if it is reduced, find out the damaged memory and replace it; If it was slow in the past, it may be due to insufficient memory, and you need to add memory of the same brand and model as the original memory or replace it with large-capacity memory.

2) Network connection failure: If there is a problem with the network settings, it may cause the system to automatically search for IP addresses and slow down, which will also affect the boot speed. If so, you'll need to check and make sure your network settings are working and set your local connection to a fixed static IP address.

3) Hard disk fragmentation or bad sectors: It is recommended to use the boot U disk to start the computer, and use special tools such as diskgen to detect and repair the hard disk under the PE system. During normal operation, you should regularly use the optimization and acceleration function of 360 Security Guard to clean up hard disk debris.

4) Power-on self-test time is too long: You need to quickly press the DEL key (F2 or other hotkeys for notebooks) to enter the CMOS setting menu when powering on, and turn off the detection of devices that are not installed inside the chassis. Such as turning off floppy drive detection, second hard drive channel, and so on.

2. Software problems:

2) There are too many boot auto-start programs: many software, especially network software, are set to run automatically at boot by default, which will greatly slow down the boot speed, it is recommended to use 360 security guard or other similar security software to clean up and optimize the computer to accelerate the processing, and you can also manually cancel the boot auto-start of non-essential programs.

3) Trojan horse and virus infection: It is recommended to use 360 Security Guard + 360 Antivirus or other similar security software to check and kill a whole situation.

If the above operations do not work, you will need to reinstall the system to troubleshoot the possibility of hardware failure.

You don't know what you say.,The first is to check the hard disk after booting before entering the system.,The second is to enter the system to load startup items and the like.,The former won't appear often.,The latter temporarily knows that your startup items are too much.,After cleaning up the software, clean up the registry.,The registry is cleaned up with 360 or the like.,Don't delete it yourself.。

Are you 64-bit or 32-bit? Is your configuration sufficient?
