My computer often won t turn on

Hard disk problems. Because there are generally weird sounds when booting up, they are emitted by the hard disk and the fan. Depending on the situation, it can be ruled out that it is the sound of the fan, so find a hard drive inspection tool to check the hard drive, there is a bad sector.

You go to the driver's home** a startup program with the same model as the graphics card, and then specify to install it to try, it may be caused by the graphics card driver is damaged, and you see if your screen resolution and refresh rate are set correctly.

Due to the limited information provided, one can only guess.

The problem you asked is that the computer often can't turn on, please check whether there is a disc in the drive when it can't be turned on, if there is a disc, the machine will start the disc in the first place, it will prompt that it cannot be started by the disc, so that it can't be turned on, and the disc should not have a similar problem.

Will you get stuck when you play a game? It's hard to say what the problem is, but a similar phenomenon may occur if the internet connection is slow.

If you really think it's slow, just reinstall the system, copy the important data to other disks before reinstalling, and back up the driver.

Reload Boot Oh also.

Happy Year of the Ox to everyone!

It's broken, changing the host can solve it.

I guess there's a problem with the machine I saved, and my computer is often broken, so I'll find a Lenovo monopoly to spend some money and let him fix it for you.

You reinstall the system and try it. No, I got it to the store where I bought it and checked the hardware. The hardware is warranted.

It is recommended not to look for it.,Want to see what to convert with software.,Even if you find it, there will be resolution and encoding problems and can't put it out.。

The reasons why the computer often doesn't turn on are as follows:

1. Leakage: Check whether the power supply and wires are not firmly connected, resulting in leakage of the chassis.

2. CPU fan problem: Check the use time of the CPU fan, such as the long-term use of the computer, it is normal to change the fan for 1 to 2 years, and some fans have quality problems, so you need to replace or clean up the dust on the fan and lubricate the bearing.

3. The case cover compresses the wires or hardware, resulting in misalignment of contact and poor connection.

4. Serious dust accumulation in the chassis: go to the electric pure blue brain city and blow it with a drum fan to solve it.

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

It is estimated that it is a hardware issue, not a system issue. The red light is the hard disk indicator, and it won't light up when it flashes, indicating that the hard disk stops reading data as soon as it starts, so there is no operating system problem at this time.

Let's use the method of elimination. Generally speaking, first see if there is any problem with the memory and graphics card, whether the power supply fan and CPU fan are working (these two fans will work from boot to shutdown), and dust the motherboard, dust and static electricity will cause the motherboard to fail. Find a good memory and graphics card and replace them in turn, and see if it can be turned on.

If the above problems are ruled out, visually check whether there are traces of burnout on the motherboard, whether there are bulges and tears in electrical components. The hard drive itself can also be problematic. Basically, the motherboard and hard drive problems can only go to the repair point.

According to what you added, basically the power button is not enough to boot the motherboard. You see if that's the case:

After pressing the power button, the computer does not respond. But after pressing the power button several times, the computer boots up.

If this is the case, it means that there is a problem with the capacitor of the power on the motherboard, and you can go to the repair point to replace a capacitor.

PS: The power button only provides a signal to the motherboard, and then the power stored in the capacitor of the power on is provided to provide an instantaneous voltage to activate the motherboard's operation. Your computer's capacitor is aging and the stored power is not enough to activate the motherboard, but press the power button several times and charge the capacitor from the power supply multiple times, and the capacitor can activate the motherboard.

Whether the BIOS self-test passes, if the self-test can pass, you can reinstall the system, if it can't pass, check the hardware!

1. It may be a problem that the computer fan does not rotate (computer aging, etc.).

2. Please check your power contact.

3. It may be caused by overheating and burning of the main engine.

4. It is recommended to let the computer cool down for a period of time, carefully check the contact of the power socket, and if you have time, disassemble the board of the host and clean it properly with a brush or rag. Hopefully things will improve.

5, hmm. It is not impossible that the power supply will break, and if necessary, you will have to buy a new power outlet.
