My computer won t turn on. Encounter the hardest problems to solve

Two possible reasons:

1.The memory is broken (most likely).

Broken (not impossible).

I don't think it's possible to be somewhere else).

Virus, reinstall the system.

Turn on the safe mode (press F8 when booting), select the safe mode, if you can't turn it on, turn on DOS, and turn on the antivirus.

Power supply issues The motherboard is underpowered.

Replace the power supply. Pay attention to heat dissipation on hot days.

Motherboard problem, use the elimination method to rule it out, see what the problem is, I think it may be a CPU problem.

The reasons for sudden shutdown, restart, blue screen, difficulty entering the system should be as follows:

The first point: some of the capacitors of the motherboard are burned. Due to the hot weather in summer, it is not surprising that many small capacitors on motherboards burn out, which is also the main reason why they can sometimes start and sometimes shut down!

The second point: the problem of power supply. If the power supply is unstable, this problem can be solved by changing the power supply!

The third point: loose memory. Some computers often move, resulting in the memory is loose, the startup will fail, pull out the memory and reinsert it to try again! This reason is rare!

Point 4: The fan is broken. In summer, the weather is hot, and if the fan is not hot, it is easy to cause a crash!

Point 5: The hard drive is broken. If a sector on the hard disk is broken, it will crash or shut down when the program needs to execute the sector!

Point 6: Computer poisoning. If your computer shuts down suddenly and can be turned on again immediately, it may be caused by computer poisoning (such as the early shockwave virus will shut down inexplicably!). ,To solve this problem, install an antivirus software,And upgrade the patch,It is recommended that you reinstall a system,If it is normal,There is no problem with the hardware!!

The seventh point: software conflicts, in the case of too many automatic running programs at startup, resource competition makes it difficult to enter the system! Click"Get started"--"Run"--Type msconfig, click 'Disable All' in 'Startup', and tick:

Antivirus + Firewall + Antitrojan + CTFMON (for example, Kaba Anti-Soft is, Rising Firewall is RFWMAIN, 360 Security Guard is 360Tary, etc.), and then restart the computer!!

I hope my answer is helpful to you, and good luck.

The desktop computer can't be turned on, probably because the power supply is not plugged in, which is very "mentally retarded", but it does exist, the power supply is not plugged in or not plugged in well, and the computer must not be turned on. If the laptop can't be opened, the first point is that it is the cause of electricity, the battery is dead, the battery is completely damaged, or the charging line is obstructed and cannot be charged normally, etc., are the reasons why the computer cannot be turned on.

Many users will now use SSD+ mechanical hard disk to assemble a new machine, which can also take into account the dual needs of speed and capacity, but after the new machine is assembled or replaced, and a new hard disk is added, they will find that they directly enter the BIOS after booting but do not enter the Windows operation interface. This is a very common problem, at this time, you need to go to the motherboard BIOS first, and select the SSD SSD in the first column of hard disk boot items, so that you can read the system in the SSD first.

Many gamers will adjust the frequency of CPU and memory in the motherboard BIOS, as well as voltage and other parameters, when the user makes a mistake, the host can not enter the Windows operation interface, at this time, some machines can not be lit, the speed of the fan inside the case is fully loaded, and the BIOS will be reset at this time;

There are also some hosts that enter the BIOS again, and still reboot to return to the BIOS interface after selecting the boot disk. The simple ending method is to restore the default settings in the BIOS, which may lead to overclocking failure due to many reasons, and I would like to advise netizens not to take it seriously, and long-term and stable operation is the key.

The third situation that can not enter the Windows interface but can enter the BIOS is the SSD hard disk crash, once the system disk fails, the system will not be able to find the boot item, and will eventually return to the BIOS interface forever, at this time, it is necessary to detect whether your hard disk has a problem, and whether it can enter the operation interface after replacement.

How to solve this problem.

It's good to ask questions and reload.

Question: How much does a hard drive cost in general.

It's easy! If it's a notebook, take it apart and take out the hard drive, buy a hard disk enclosure can also be used as a mobile hard drive, and desktops can also buy an inch box!

If you only need data, you can hook your hard drive to another computer and read it!

It is recommended to use a USB flash drive PE to repair the system, but if it does not solve the problem, consider reinstalling the system.

1. Make a U disk PE system on other machines, you can try U Master.

2. The U disk is inserted into this computer, and the boot is set to the U disk to start, and enter the PE system.

3. Open the system repair software on the desktop, repair the C drive automatically or manually, and close the software. Open the partitioning software, right-click on the hard disk, and rebuild the Master Boot Record MBR.

4. Restart the computer, unplug the USB flash drive, and wait to enter the system.

Have you changed anything recently, such as drivers, or installed software?

1. Restart the computer, press F8, and the selection menu will appear. Road.

2. Select the last correct configuration, try the security mode, if you can enter the security mode, you can uninstall the recently installed software or driver.

3. If this is still the case, you can only redo the system.

You power off the main engine first, then disassemble the main engine phase box cover, remove the battery on the motherboard, and then install the battery back after about 3 or 4 minutes, and then you turn on the computer again!! If it still doesn't work, it may be a problem with the power supply of the case, and you can only change the power supply!

Here's how it can be done:

Select"Reset this PC (System Settings).

In"Advanced Launch)."Next, select Restart Now.

Choose an option.

Follow the on-screen instructions to complete the reset process. This will take some time and your computer will restart.

The landlord probably meant that if the system was broken.

Find another system to carve it on.

Or you want to use an optical drive to install the system.
