The computer is seriously abnormal, and the computer system is abnormal

Based on your description, the recommendations are as follows:

1. Turn on the machine for three minutes - if you use it for a long time, this is not the time for the optimization master to clean up.

Please back up the contents of your desktop and My Documents, and then reinstall the operating system.

If you feel the need, you can add a memory module, or upgrade the CPU or even the entire computer hardware system.

2. Sometimes the connection is often dropped and the web page speed is slow - call your access party (telecom or Netcom customer service) to report for repair, and ask them to help you test the speed and improve the network in the computer room. Check whether your network cable crystal head is to be replaced, and update the network card driver. Cats have only been used for 1 year, and there are generally no problems.

3. I haven't dusted it for a long time - whether it's a laptop or a desktop, it's best to clean the dust once a year.

Prepare tools, silicone grease, etc., and clean them as soon as possible.

Can I connect to it after I have dropped it? When you can't connect, see if your cat has three lights that are always on? If the light is not on or is flashing, there is something wrong with the cat.

Frequent disconnections should mean that the network is unstable, and it should not have much to do with the computer. How many m of broadband are you? Let's see if the speed of the test is normal.

If the internet speed is abnormal or the connection is frequently dropped, call customer service directly. There will be staff to help you solve it for free. Otherwise, you won't be able to find the problem yourself.

Let's be poisoned, let's make a system.

The problems need to be eliminated one by one, first remove the dust, and then sort out the boot items, you don't need to cancel all the boot starts. All that's left is to use software such as Optimizer to optimize the machine, organize the memory, and so on. OK.

Dust first and then redo the system That's the only way to remember not only the C drive, but also the other disks.

You can try changing the CPU fan.

First clean the computer thoroughly, and the next optimization master will optimize the system to clean up a garbage.

Symptoms of poisoning, reinstalled the system? If you don't have it, try it again, or restore it.

It is recommended to redo the system after dusting.

There are built-in repair tools to give it a try.

2。If not, it is recommended to redo the system.

Summary. Press the three keys (Ctrl+Alt+Del) to restart the computer processing, however, after pressing it, it will return to this realm.

There is also an anomaly that when installing, remember to install it on the C drive, and it turns out that the operating system is installed in the USB flash drive. The reason for this is that because of the U disk PE system, the disk letter is a little out of order, when installed.

Some installation operating system abnormalities are due to the use of optical disc installation, and the optical disc is easy to scratch, or the head reading error, resulting in some files can not be read to the hard disk normally, so the installation fails, at this time.

There is also a situation where an error occurs when using a tool such as one-click restore to install the clone version of the file, and the biggest possibility is that the path or installation file uses Chinese and the like is not recognized by this hard disk installation tool.
