What should I do if something goes wrong with the computer slides?

Solution to the black screen of the monitor: 1. If the monitor is not used for a long time, the monitor will automatically enter the sleep energy-saving mode and the screen will be black. Workaround:

Take win7 as an example. (1) Right-click on the blank space of the desktop, select "Personalization" in the menu to open the personalization settings dialog box, (2) Click the red box in the above figure to select "Screen Saver" to enter the screen saver settings dialog box. (3) Set the screen saver to "None".

And click "Change Power Settings" to enter the power settings dialog box. (4) Click "Change Plan" to enter the change settings dialog box. (5) In the blue box selection, click the drop-down triangle, select "Never", and then "Save Changes" to exit.

After setting, the monitor will no longer automatically go black. Second, the display failure causes a black screen. On the internal power board of the display, the capacitance of the power supply output part is aging, leaking, bulging, and failing.

When the display is first turned on, because the capacitor is not completely necrotic, in a short time, the power supply is normal, so it can be displayed normally. After working for a period of time, the power supply is seriously insufficient, causing the backlight of the LCD monitor to go out, causing the display to go black. Workaround:

Send for repair professional display maintenance point, worse damage components, the cost is about 30---50 yuan. 3. The signal line of the display is loose or in poor contact, resulting in intermittent signals transmitted to the display, resulting in a black screen of the display. Workaround:

Replug, replug, install and fix the signal cable of the monitor. If the fault persists, the signal cable can be replaced. Fourth, the performance of the graphics card is faulty and unstable, resulting in a black screen of the display.

Solution: 1. Test after updating the graphics card driver, if the fault persists, directly replace the graphics card for testing. Note:

If you're using an integrated graphics card, you can install a discrete graphics card for testing. Or directly replace the motherboard with integrated graphics for testing. 5. The motherboard performance is faulty and the operation is unstable, resulting in a black screen of the display.

Solution: Directly replace the motherboard for testing.

You can take a screenshot of such a question and there is no way to give you a detailed answer.

The computer can't be turned on: mainly due to the problem of power supply and cable, first of all, it is necessary to judge whether the capacitor on the motherboard has a bulging image. If not, you'll have to check the power supply and the jumper on the motherboard.

First of all: I want to explain to you that if the memory can't be turned on, it will only prompt no signal input: 2:

If the graphics card is broken, the fan will turn, which means that there is a problem with the card. No. 3: Take the most serious place:

Motherboard: The first motherboard should take into account the capacitors and the jumper of the motherboard: you can unplug it and reassemble your computer:

By the way, clean up the dust: if you still can't turn on the machine in the case of reorganization: landlord, please use one end of a plum screwdriver:

Put it on the jumper interface on the motherboard power supply, turn on the power supply and gently touch it to see if the CPU fan turns ** The cable is not plugged in first, because here I want to note that even if there is no cable, your computer will run, because the metal of the plum blossom screwdriver is conductive, so don't use the same wire to judge the quality of the machine: don't use a screwdriver that is all metal because it will touch yourself:

If the CPU fan turns. It means that there is no problem with the motherboard, the problem is in the cable, if the CPU fan does not rotate, then judge the power supply: first unplug the power supply plugged into the motherboard, and use a pin:

Plug in at both ends of the positive and negative ends of the interface of the power supply: look at whether the power supply fan is moving, and if it does not move, it means that the power supply is broken, just change it.

Graphics card You need to make sure that your graphics card is in good contact with your motherboard interface. The landlord can check it himself first: if there is anything you don't understand, you can add q 59812316:

This situation means that your office lacks the components required to open the file, that is, your office is not fully installed, you can re-run the office software, and install all the components.

If you don't have a complete installation and need to have a disc, fix it, or reinstall it, just change it to the 2010 version.

Office2003 version of the text is different from the office2007 version of the general question:

If you create a lower version, you may not be able to open the higher version, and sometimes you may not be able to open the lower version, so it is recommended to install the office2003 and office2007 compatibility package. Microsoft Chinese official ** has the following.

If the ppt is created by yourself, it should be able to open, but my own experience believes that there are two possibilities that cannot be opened.

1) I am not the original creator, and I can't open it when I receive someone else's PPT, but I can open it on the author's machine, which means that the office version used by 2 people is different, and sometimes a genuine or pirated office PPT can't be opened. The reason may be a version issue, which is more complicated. If the content of ppt is relatively simple, only text, etc., it can't be opened because the ppt bottom plate is different, that is, the author changes the personality base plate in order to look good, but there is no other machine so it can't be opened, this is a common problem.

2) The same computer is still rare to write self-remembering after the creation of the software problem, it is estimated that the office itself software problems, it is recommended to use genuine office, pirated after the update is prone to problems, do not update the time often will also have problems. Find a genuine serial number, enter it when you reinstall Office, and then try to type the file.

The general solution idea of PPT that cannot be opened due to system problems: If you can't solve the problem by reinstalling Office, use optimization software to patch the system vulnerability, and if it still can't be solved, you can reinstall the backup of the backup and reinstall the system.

Mimicall phone bill software.

Seeing that the icon in the upper left corner of your screenshot does not correspond, do you see if your file name is PPT in the future? If not, just change it.

The natural problems of computers that are not used are also different, so let's analyze and analyze them together.

If the monitor doesn't light up, it's mostly a problem with the memory or graphics card.

You unplug the VGA cable of the monitor, plug it in separately and turn it on, if there is a no signal interface prompt, it means that the monitor is good, and the rest is to check the data cable. Graphics. and memory issues too.

In most cases, it is due to dust, and it is okay to clean the graphics card or memory, if the display is plugged into the power supply separately, it is not lit, it is necessary to consider whether there is a problem with the circuit board of the display, in this case, it is necessary to send it to the maintenance station for maintenance.

Generally, the power cord end is loose and there are several connecting cables.

Try again after plugging it back in.

Hello:——1、"The computer monitor is not powered on"...There is no doubt that the fault is on the power supply.

2. The power supply of the display is a high-frequency switching power supply, and the input fuse, power switch, high-frequency ** circuit and voltage regulator circuit should be checked.

3. The electronic technology and maintenance skills involved in the switching power supply are very high, and friends who are not familiar with the circuit should be sent for professional repair.

1. The circuit connected with the display is not energized: first turn on the power switch of the display, if the power indicator is not on, then check whether the power cord plug on the back of the monitor is loose or fall off, plug it up tightly and check whether the power cord is plugged into the socket and whether it is energized, if the circuit is energized and the plug is plugged in tightly, then the indicator light should be on. Otherwise, it's the second possibility.

2. The display is damaged: If the display itself is damaged, it will not be able to light up even if the above operations are carried out. This can also be determined by replacing the monitor, such as connecting this monitor to a normal host or connecting a normal monitor to this host for testing.

If this happens, you will have to replace it with a new monitor.

If you don't understand, you can ask me, I hope it can help you.
