Computer problems, suddenly not showing up!

See if the graphics card is plugged in, the cost is not clear.

Well, I've seen this kind of problem, it's usually a graphics card problem, do you smell the smell of burnt wires, and the wires inside touch the graphics card? And maybe the power supply voltage is not enough?

Is there any reaction after the power switch of the monitor is turned on and off?,It won't be that the power supply is not plugged in。

If there is no response at all when you press the power of the monitor, it is not the power cord that is in order.

Give someone else a motherboard jumper! It's best to take it to Shenzhou's after-sales service.

Don't hack those little shops.

It is likely to be a kind of poison, look at whether your network indicator light flashes normally, if the indicator light flashes quickly, it means that your computer is still running, indicating that the other party is likely to operate your computer as soon as you are deceived. But if you're playing a game, the screen may also be the cause of the system.

1.The graphics card is broken2Virus Black Screen 3The hardware is overheating.

My computer also had this kind of problem some time ago, mainly because it was damp and the heat dissipation was not good.

Buy a heat sink, it's 30-70 yuan.

Don't rush, maybe it will be fine on its own in a few days.

Hope it helps you o(o

Your problem should be a common problem with the computer, it's very simple, first check the problem, see if your power supply is charged, whether the fan is turning.

If it's not a problem with the wiring, then that's it, you unplug all the cables on the motherboard that can be pulled out, and some hardware such as graphics cards are pulled out, wipe them clean, stay for a few minutes and then plug them back in place, if not, then please remove the motherboard standby battery, and install it again after a few minutes. Almost everything can be solved in this way.

If you turn on the computer and see that there is a lot of English, it means that you have succeeded, and you can not restart it when the English does not enter, keep pressing the "delete" key to set the system time, because you unplugged the motherboard battery so you have to reset it. Generally, it is below or above the first line, press the "F10 key" to save the settings after setting, and then restart the computer to be OK.

It's definitely not a problem with the display.,It's either a problem with the cable connecting your host to the monitor.,Or it's a problem with your socket.,,I'm guessing too.。

If the previous few can't solve the problem, it is recommended that you check the capacitance inside the monitor! There is aging, and the one that changed the drum is replaced....Personal opinion, for reference only....

Well, there are many reasons for this situation, most of them are caused by memory modules, graphics cards, moisture, dust accumulation, poor contact, you can get it yourself a little bit, if it doesn't work, it may be a broken motherboard or something... That can only be taken and repaired...

The bright orange light is in the power-saving state, plug the signal cable connected between the host and the monitor again, (VGA is blue, DVI is white) Replug both ends, and lock the screws. If it's not good, go to after-sales! Good luck.

The cup hasn't started up for a long time and can't work all at once, or the CPU is too hot.

The first rebootThe second reload graphics card driver

Install the driver. Third, reset the nvidia control panel

Reset the NVIDIA Control Panel.

Fourth, it should be fine

nvidia experience

It means that there is no signal input, and there is no signal input on the black screen when booting up, so first rule out the poor hardware contact.

1. Unplug the peripherals and start the computer, and re-plug the display data cable and various power cables.

2. There is a discrete graphics card display data cable to be connected to the discrete graphics card.

3. Open the chassis to clean the inside of the chassis and clean up the dust.

4. Reseat the hard disk data cable and power cable, and check the power supply of the graphics card with an independent graphics card.

5. Buckle the motherboard battery discharge to solve the problem of static electricity.

6. Reseat the memory, use the eraser to erase the gold finger of the memory graphics card7. Unplug the independent graphics card display and connect it directly to the integrated graphics card of the motherboard to eliminate the graphics card problem.

The main unit does not start normally, and the message displayed on the screen means that there is no signal input.

Reboot and select proper boot device means: find the device that cannot boot, and the possibility of hard disk failure is high.

1. There is a problem with the hard disk, and there is no hard disk option in the startup item, which is caused by the poor contact of the hard disk, the problem with the data cable of the hard disk, and the broken hard disk.

1. Open the case and re-plug the hard disk data cable and power cable, and then try to turn it on.

2. Replace one hard disk data cable with the motherboard interface and one power cable.

3. Replace the hard disk data cable and replace the hard disk.

2. If the MBR partition of the hard disk is damaged, use the PE boot disk to repair it. Prepare the PE boot disk and insert it into the computer, and press the start shortcut button continuously when the boot is turned on.

Select the U disk or CD-ROM PE boot disk to boot into the PE interface, select Win8 PE to enter the PE desktop, and open the partition tool Disk Genius

After repairing the hard disk, click to rebuild the main boot MBR.

Go back to the PE desktop and select the C drive for repair.

3. I can't find the hard disk in the partition tool Disk Genius, the hard disk is broken, replace it.

Try to try a different version of the graphics card driver first, and it is recommended to use a driver that has passed the WHQL certification, because it is indeed very common for the graphics card driver to be incompatible with the program itself or the possibility of bugs in the driver. For some graphics cards, you can also try disabling AGP FastWrites and AGP Sideband in the motherboard BIOS.

If none of the above methods work, then you have to reinstall the system, which can solve many problems in daily maintenance. After installing the system, install the drivers in the correct order: Windows XP SP2 patch - motherboard driver - graphics driver - sound card and other PCI device drivers - peripheral drivers.

When the driver installation order is not normal, there may also be some problems, and the driver installation order is related to the underlying device driver, registry key value and gart mapping list.

Check the heat dissipation of the graphics card, touch the temperature of the graphics chip with your hands, and check whether the fan of the graphics card is stopped. Then look at the AGP PCIe slot on the motherboard to see if there is dust and whether the gold finger has been oxidized, and then clean up the dust according to the specific situation, wipe the gold finger with an eraser to polish the oxidized part. If there is a problem with heat dissipation, change the fan or add a heatsink to the video memory, or go to the BIOS to see if the voltage is stable.

For the phenomenon of long-term pause or crash or blurred screen, on the premise of excluding overclocking, it is generally caused by insufficient power supply of the power supply or motherboard slot, and it is recommended to replace the power supply to try it. For the power supply problem, many brands in the DIY market (including several big brands that are currently louder) have a nominal power supply of 300W, but the actual output power is only about 230W. Many graphics cards are already products with high frequency, high temperature, and high power consumption, and the requirements for power supply are also increasing.

It is recommended that players with conditions pay attention to the actual output power calculation when purchasing, and it is best not to buy miscellaneous power supplies. Try not to buy a chassis plus power supply for less than 200 yuan cheaply. In addition, if the graphics card slot is not supplied with enough power due to the motherboard's design flaws, you can try to increase the voltage in the motherboard's BIOS.

If the graphics card is still blank after the above methods, you can try to flash the BIOS of the graphics card and go to the home page of the graphics card manufacturer to see if there is an updated BIOS**. You can try flashing your graphics card with BIOS.
