What should I do if the computer doesn t start at all?

Based on the situation of the landlord, the computer does not start at all, you should rule out the software, display, sound, memory module problems, then the only possible problem is the failure of the hard disk; Problems with the power connection socket; The regulator is damaged. It is recommended to drag a repair person outside to check, they have all tools, and the door-to-door fee is roughly ranging from 20 to 50, you can bargain, I wish the landlord a computer as soon as possible.

It's too long to play, the CPU temperature is high, and you can clean up your computer host, wipe everything that should be wiped off, it's okay, I often don't turn off the computer for 1 week, just turn off 1 hour 2 a week, and sometimes it's like this, and I don't move anything, so I dismantle what is it and clean it up, and it's OK if you're in a good mood, just change the system.

Insufficient heat dissipation, CPU overheating, automatic breakpoint self-protection, try to change the CPU again, if it doesn't work, it's the motherboard is broken.

Two places

You'd better pray first

You see if there's electricity on your mains, and if there's no power, congratulations, your prayer God received it, and if there's no power, it's probably going to kill you. 。

The second ... First of all, did you do anything bad yesterday?? If you do. Prayer is useless 80%. Kill your motherboard and pray. Brothers...

Also, if you're sure it's these places

It is recommended that you check your home's power supply to see if there is any problem, like this situation, it is likely to be caused by too high voltage.

Don't turn anything is not a matter of hard disk, if you don't, don't mislead people First look at the power supply, whether there is power, no power, change it, there is power, the motherboard hangs 80% is the fault of the power supply.

It may be that some hardware is burning, so take the host to the repair place to check it.

If the above still doesn't work, try restoring the system, or reinstalling the system.

First of all, let's analyze the reasons, and sort them from the most common to the rare: memory - motherboard - power supply. Depending on what you describe, 4 and 5 are more likely.

1. Memory. This is the most common and most common cause. The vast majority of them are caused by poor contact, you can remove the memory module, wipe the gold finger on both sides with an eraser or alcohol, wipe the oxidized metal surface clean, clean the memory slot with a dry brush, or insert the memory module into another memory slot, if there are more than two memories, you can run the test on a single strip to eliminate the fault memory module.

If it doesn't work at once, you can wipe it several times, so that most people's problems can be solved. (If you have a discrete graphics card, you can also clean it up, and the operation method is the same as the memory module). If you still can't start the computer normally, you can change a memory module of the same model for testing, if you change the memory module can be solved, that is, the original memory module is damaged, just buy a new one.

2. Motherboard BIOS error. Motherboard BIOS errors can also cause this problem, you can discharge the motherboard, that is, reset the BIOS, remove the coin cell battery from the motherboard, leave it for a few minutes, and then install it back. If there is a jumper, it is also possible to use the jumper short.

3. Internal dust or static electricity. After a long period of use, the computer will inevitably accumulate a lot of dust, and sometimes dust will cause some parts to be in poor contact. It is recommended to use a high-power hair dryer or air pump for dust removal operations.

4. Power failure. If none of the above methods can be restored to normal, then it may be a power failure, which will be caused by a burned power supply or too low power. The solution is to change a power supply test, the general family does not have the conditions, you can go to a professional repair shop to find them to help you test, if you change the power supply, just buy a new one.

5. a motherboard. If you still can't start the computer normally after changing the power supply, then you have to consider that the motherboard chip is faulty. The same is to let a professional repair shop test for you, if you can repair the motherboard, if it is not easy to repair or too expensive, it is better to directly change a motherboard.

How should <> be checked?

2.If the power supply is okay, then see if there is a problem with the monitor, try to change to a normal monitor.

3.If the display is normal, then consider whether it is caused by the static electricity of the computer can not be turned on to change the trillion more, first unplug the power supply and roll the nucleus, and then hold down the power start button to guess the difference can be more than 10 seconds, press it twice more, try to see if it is good, if it is not good, then look at the following method.

4.Disassemble the case, take the memory module off, take something to wipe the dust off the gold finger, and put it back in. This time, press power on to see if your computer can boot up normally, the following picture shows the common appearance of the memory module in the computer.

5.If the computer still can't start normally, you should consider whether the computer's memory module is broken and the computer can't turn on, if there are two memory modules on the computer, then unplug one first, if it is not good, then press the one you just unplugged, and unplug the other one. If it boots normally, it means that the unplugged memory module cannot be used on this computer.
