The computer boots up very slowly, and it still can t move when it starts

Reduce the number of processes that start automatically at startup.

Update the card bar to fully disinfect the virus

At the same time, you click Start--Run Input: msconfig Leave only cftmon and antivirus software in the startup, don't choose anything else!

Install Rising Card Internet Assistant to clean up startup items, processes, illegal plug-ins, system vulnerabilities, etc.

Ditto: If it doesn't work, reinstall the system.

The reasons why the computer won't turn on and how to deal with it are as follows:

1) The first reason: is the problem of the power supply, due to the fuse of the power supply burned out, the rectifier diode is damaged, the switch triode is broken, the main transformer is damaged, the filter capacitor is exploded, and so on, it may lead to failure to boot, boot no response, detection and treatment method: open the host, find the plug-in cable of the motherboard and chassis panel, and remove the motherboard power switch pin wire (power

sw), while the pins on the motherboard are: PWR

SW or ps on, two small square steel needles (as shown below), and then use a slotted screwdriver, short these two pins, if the host power will turn, this means that the power supply is normal, if it will not turn, this means that the power supply is broken, and the mold can be replaced.

2) The second reason: there is a problem with the plug of the host, check whether there is a problem with the plug and socket. Reconnect.

3) The third reason: is that the boot circuit of the motherboard has the problem of renting and matching birds, such as clock, reset, CPU power supply, MOS tube, etc., which may cause the failure to boot, as well as the virtual welding problem of I O, Nanqiao, etc., there will also be frequent black screen and can not be turned on, etc., the solution: is to repair the motherboard, (if during the warranty period and after-sales service).

In fact, the electric carrier can't turn on the computer, and it is generally not caused by a virus, because the virus is software, which is basically loaded after booting, which will only make your system run abnormally. Generally speaking, the computer can't be turned on, all because of hard problems, and there are many kinds of hardware problems, I just say a few common ones that don't need to replace the hardware! (There are also software problems, but they are generally caused by accidentally deleting the system boot file, which requires reinstalling the system, here are just common hardware problems!)

1. There is too much ash in the computer, and more ash will cause heat dissipation difficulties in the computer, and many hardware will not work properly, resulting in the inability to turn on!

2. The hardware is loose, sometimes because the computer has been used for too long, some parts will be loosened, and it will shake as soon as it works, and the computer will naturally not be able to turn on, especially the hard disk and power supply! As long as the screws are put on well, there will be no problem.

3. Slot aging.

When the computer is long, the socket will age, resulting in poor contact between the gold fingers between the hardware, sometimes there are problems with the sockets of the motherboard, and sometimes there are other hard gold fingers aging!! Generally, if this kind of problem occurs, you just need to change the slot, or you can use an eraser to wipe the gold finger. One of my classmates is that the memory slot is aging, and it would be nice to change the slot!!

At the same time, this problem is also the most common. Many times, when using the computer, some people lose their hardware because of this reason!!

4 Voltage problems, the voltage in your area is unstable, or the voltage is too low! 1 I can't help this situation, buy a voltage regulator or something, you can alleviate it!!

The above is the common problem that the computer can't turn on, these problems are very common, and it's not troublesome to solve, as for the hardware to be replaced here, I won't say it, you get the place to repair the computer, others will repair it for you!!

Usually there is a problem with the hardware (hard drive), and it is also possible to be poisoned. If you can go into the system to see in the antivirus, if it doesn't work, the problem should be cracked, and you can solve the problem by replacing the hard disk through this source.
