My computer is very slow, especially when it comes to shutting down and turning it on.

It's been a long time since you've cleaned your computer!

It is recommended to disassemble the computer first and wipe it with a damp cloth and toilet paper respectively (in the case of short power)!

Especially the position of the fan, the hole may be blocked by dust!

Then reinstall the system, don't install too much killing software on the computer, because you can't bring it up if the machine is not good!

Is it that you boot up slowly, and a lot of default software runs automatically when you boot up? If yes, it is advisable to cancel the autorun!

There may also be computer worms or malware or Trojan horses, and you should check them out as well!

Slow internet speed? What network are you and how big is the traffic?

Slow shutdown and boot speed, is it because you have too many startup items? Or is your computer getting old?

What does that mean? Why do you still turn on and off? How do you look at the network speed when you turn it off?

It doesn't seem to be possible to turn it on? Do you mean that the network speed is slow or the system is slow, if the network speed is slow to find a Netcom company, only viruses and worms can hinder it, and the software will not play a big role, even if you are infected with viruses and worms, you should be able to clean it with Kingsoft Antivirus. So it's still the reason of the network communication company, or you will change the network cable.

I don't know what question you're asking, is it a slow network speed or a slow shutdown and boot speed?

In the case of the Vista system, the power on and off is relatively slow, and it is normal to turn on and off within 2 minutes.

Reason: Laptop shutdown is slow and boot is slow, because with the use of the computer, the installation of various software, the computer system will produce a variety of system garbage and registry garbage, etc., and many software and systems have automatic update function, to a large extent for the system to bring a lot of burden. In addition, long-term storage of hard disk and deletion of files can also easily lead to a large number of fragments in the middle of the hard disk.

Solution: 1: Turn off the system automatic update function.

Many programs in the computer application do not need to update the software version frequently or are not needed, so the automatic update function can not be turned on at all, but it is enabled by default, so Weiheng needs to turn off the automatic update function of the system.

2. Frequently disinfect the computer and clean up the system junk in time.

This operation is generally done once every three months or so. The disk defragmentation method is also relatively simple, go to my computer to find the system disk (usually C drive), right-click on it and select properties, and switch to "Tool Options".

Select "Start tidying".
