I would like to ask what to do if my computer suddenly breaks?

There is no way, because of the hardware involved, there are too many lines, and it is time-consuming and laborious to check, so it is best to prepare a laptop for backup.

I am sad that my laptop suddenly broke down, and I don't know what to do, all netizens help.

1. After some computers with higher configuration levels come over, mainly check the appearance of the monitor, whether the displayed image is still clear, and then look at the brand and configuration of the computer, and then sell those useful parts after upgrading or reassembling and debugging.

2. If the computer is those useless waste computers, it will be sold to a special computer garbage disposal plant, if the picture tube of the computer monitor can still be used normally, it will be reused, about 70 yuan, if the picture tube of the point display is bad, then it can only be sold for about 20 yuan, the abandoned host is usually refined by metal, about 1 kilogram of motherboard can be refined out of about 250 grams of copper. However, refining metals will cause a certain amount of pollution, and now the state only allows some formal factories by the sea to refine it.

3. Some ** computers will be reused, and after a slight modification, they will be sold to some small Internet cafes or individuals.

Take the repair shop to fix it!

Repair it, you can generally repair it, and if you can't repair it, you can't rematch it.

Do you have any other options than repair? Otherwise, buy another one.

Try to replace the power battery first, if it doesn't work, the parts of the machine itself are loose or the chip is damaged by virtual soldering, common reasons: the memory is loose or there is a problem with the memory itself, reinsert the memory or change the memory to try.

The system fails to boot and the boot device is not found. The self-test did not detect the hard drive, which is relatively high in the possibility of hard disk damage (it may also be caused by the BIOS settings causing the hard disk to shut down, the circuit related to the control hard disk on the motherboard is damaged, or the hard disk interface is not in good contact).

This problem should not be big, and it can generally be solved by yourself for testing:

You can press the "F2" key to enter the BIOS setup interface when the Toshiba screen is displayed, see if you find the hard disk, and at the same time restore the factory default value to try it;

It is useless to restore the BIOS settings, you can re-disassemble the hard disk to try it, by the way, see if the hard disk interface is oxidized and dirty, if so, use an eraser;

If it is useless to disassemble and assemble, you can consider replacing a hard disk, or connecting the hard disk of the machine to another computer for testing to rule out the problem of hard disk or motherboard.

Obviously, go to the boot option, find the boot order, and then set the HDD to boot first.

I took a look, and this hard drive of your laptop was dismantled, and I guess it was someone else's garbage book for you. 2G RAM, 1st Gen i3Go to the computer city, buy accessories, and add memory to upgrade to the top configuration. Add an SSD,

The computer is not broken, you go into the BIOS to see if the hard disk can be detected, if it can't be detected, it proves that your hard disk is hung and replaced with a hard disk. If it's not broken, make sure that there is a system in your hard drive, then rebuild the MBR, and you're good to go.

It could be a graphics card.

Or the memory module is loose.

You open the case and plug it back in.

Clean up the dust inside the chassis as well.

The desktop I add sometimes has this problem.

The chassis is running.

The display does not reflect,
