The computer is slow, the drug detection is non toxic, and the network speed is very slow when the c

I once encountered a similar problem, it was reinstallation and antivirus, and later I found out that the CPU fan was broken and the heat dissipation was not good, which caused the CPU to automatically downclock. Open the case and take a look.

The system will generate a lot of garbage over time, so it will be slow. You clean up the system junk and you're done.

Organize the disk fragments, the more fragments are very slow, maybe the hard disk is broken.

The second and fourth floors are right, there are many reasons why computers are slow.

Anyway, when I'm fine, I like to kill and disinfect, clean up the disk or something.

The load on the computer is too great, and the thin donkey pulls the grind, and it definitely can't be fast.

Let's check it out.

If you can redo it, you can redo it on the C drive, and keep 20g

If you delete the junk files on the C drive without redoing it, it may be that the C drive is not enough.

This is also the case with my computer, so I might as well try Deep Restore.

The computer configuration is not good, it is not better than the human brain, you can reinstall the system, it is not good, then I don't know.

Hehe, I've never dared to trust Kingsoft Poison Bully and Rising Stars. It is recommended to change a good antivirus software to enter the safe mode to scan and clean up the virus residue.

You can find the virus according to the location of the virus scanned out, and kill it manually! This is the most direct method, and it really can't be restored with one click!

I recommend using advanced antivirus software to kill, and reinstall the system if it can't be cleaned

It is best to install antivirus software to scan the system, 360 cannot deal with viruses at all, and now viruses are rampant, it is recommended to install antivirus software as soon as possible and go to safe mode to scan and kill the system.

There are many reasons why computers are slow to respond.

1: Poisoned.

To be antivirus. However, sometimes antivirus software can't detect viruses.

That's what you said.

But if the computer is poisoned.

You should be able to detect it yourself.

For example, there are a lot of files in the system for some reason.

2: There is too much garbage in the system.

It should be cleaned up.

Cleanup software a lot.

For example, Windows Cleanup Assistant.

360 Security Guard.

Windows Optimizer.

Super bunnies and more.

3: The computer configuration is outdated.

Run current programs with outdated configurations.

Due to the configuration is too low.

Of course, the computer will be very slow to respond.

For example, my computer at home is very stuck...

That's all for the basic reasons.

If there's anything you don't understand.

Go for it. Everything.

Remember. It's our best teacher.

1.Problems with your operating system (including missing files, viruses, Trojans, too many disk fragments, etc.)2Problems with your browser (including missing files and being hijacked by rogue software)3

There is a problem with your network hardware (including routers, network cards, network cables, etc., such as hardware failure, magnetic interference, etc.)4Problems with your network provider (including the non-telecom network you choose such as China Unicom Netcom, etc., their bandwidth is limited, generally telling you that you are 2M, but sometimes only tens of K, and the network is particularly unstable when it is busy)5Weather reasons, including thunder and lightning, etc. 6

System setting problems, some operating systems have limits on the number of network connections (for example, the default number of connections for XP is 10) and the hardware driver is not equal Copyright Statement: This answer is the original of a petty bourgeois man, and no one may steal it! Other reasons:

1.There is a problem with the ** server you want to access or the game server you are logging in2The ** server you want to access or the game server you are logging in to will not work on the network (please refer to clause 4 above)3

The amount of **server you want to visit or log in to the game server** is too large, resulting in overwhelmed servers, reduced efficiency, etc.4There is a problem with the program design of the ** you want to access, and there is a problem with the program design of the game server, which leads to too many bugs, which affects your normal browsing or playing games, and makes you feel like you think the network speed is slow5The server you log in to is Netcom, and you are a telecom network, there is a difference in speed when accessing each other, this is quite obvious when playing games, when you access the Netcom server in the telecom network, it is painful and very slow.

Check it out for yourself.

1. It may be caused by the instability of your network, it is recommended that you check whether the local network is abnormal first, or try the online game accelerator to solve it. Open Tencent PC Manager - Toolbox - Test Internet Speed (Internet Speed Protection).

2. Configuration reason. The configuration doesn't match the game standard, so can't you afford to bring a large game? Graphics cards, memory, CPUs.

3. If there is a virus or Trojan, it is recommended that you **Tencent Computer Manager, and then take a full antivirus, if you encounter a Trojan, you can use software management - search for [stubborn Trojan Killer] - strong investigation and killing.

5. Is there an ARP attack? Turn on the firewall and open PC Manager - Toolbox - ARP Firewall.
