Ask a friend who is knowledgeable about computers a question

Adobe Flash Player is a ** plug-in, not a virus, it is recommended to use 360 security guards to clean up the system, and then upgrade Jiangmin antivirus software to the latest version to kill viruses.

Secondly, your computer is not heavy with too many viruses, it is recommended to go to the Internet and download some tools with clear plug-ins, clean it up, and then use Jiangmin Antivirus, remember to upgrade the antivirus software before antivirus.

I don't know.

I'm convinced.

1 The computer should be kept in a clean room. Dust can adversely affect almost all parts of a computer, shortening its lifespan or affecting its performance.

2 The computer should be placed in a spacious space, and the heat dissipation space should be reserved around it, and it should not be mixed with others.

You can find some shortcuts on the Internet, or find some electronic magazines to take a look, you can know a lot of knowledge, there is a word limit here, there is no way to talk about it in detail,

Install another browser and try it, fix it with 360 or Super Bunny, and reinstall it if it doesn't work.

Yes, computer knowledge includes hardware systems, software systems, and network systems.

Software systems include: operating systems, application software, etc. Application software in the computer industry management software, IT computer industry development essential tools, computer industry ERP software.

The hardware system includes: chassis (power supply, hard disk, disk, memory, motherboard, CPU ** processor, CPU fan, optical drive, sound card, network card, graphics card), monitor, keyboard, mouse, etc. (can also be equipped with headphones, speakers, printers, **, etc.). The motherboard of home computers generally has an onboard sound card and a network card.

Some motherboards are equipped with integrated graphics. Network systems include: workstations (terminal equipment, or clients, usually PCs), network servers (usually high-performance computers), network communication equipment (network switching equipment, interconnection equipment, and transmission equipment).

Including network cards, network cables, hubs, switches, routers, etc., network peripheral devices: such as high-performance printers, large-capacity hard disks, etc., network software: including network operating systems, such as UNIX, Netware, Windows NT, etc.; Customer connection software (including DOS, Windows, UNIX operating system, etc.); network management software, etc.

Let's use an analogy! A computer is like a person, a computer motherboard = a person's body, and a computer CPU = a person's brain. Computer memory = liver in the human body, computer graphics card = human eyes, computer hard disk = human stomach, computer system = human mind!

Hehe, so those things are indispensable, and one less is not good! If you need to know about the hardware of the computer, it is recommended that you go to the bookstore to find the basic computer knowledge textbook to read, which will introduce it more comprehensively!

Your question may be deleted.

Yes, that's not a problem.

The memory usage is very high, so the card, 1G of memory is absolutely no problem to run QQ, the reason is that there is too much garbage in your machine, too much cache, you can ** a 360 security guard to clean it up, if it is not improved, you can also format the C disk, redo the system, the garbage is cleaned up more cleanly, the ghost pirated disk on the market is only a few dollars, and you can install it yourself. (If a card is a few minutes I suggest you do the system, it may be that the system files are lost).

2.Disconnection: If the network provider is not a problem, it is a problem with the equipment, and the two should be using it together There should be a routing problem (the normal router will not be disconnected, even if it is a 1 trillion network speed for you to use, the card will appear, but it is impossible to disconnect).

3Call your local network operator to get the network cable IP and use a fixed IP address to access the Internet, or the two of you can discuss, consciously use as little network TV as possible, and try to use Thunderbolt to watch movies, Sohu, Kuliu, etc., which occupy less traffic, so as to better solve the problem of your stuck machine.

First see if your home's broadband is telecomic, other broadband is prone to problems.

Is there a virus in the system?

I think it's best to find a computer repairer to look at Z

1. The last correct configuration: Before booting and booting into the operating system, we press the F8 key, select "Last correct configuration" and press Enter. This method can only solve the situation that you can't enter the system due to configuration problems (such as the blue screen caused by replacing new hardware or loading a new driver), because this method is simple to operate, so you should first take this method when you can't enter the system;

2. Safe mode: If the "last correct configuration" can not solve the problem, it may be a little tricky, but it doesn't matter that we still have a magic weapon, yes, that is the safe mode, the purpose of entering the safe mode is to check and kill the virus (in many cases, the computer can not enter the system because of the virus), after thoroughly checking each drive letter, restart the computer to solve the problem;

3. Windows system restore: This restore is not more than restoring, and we usually talk about redoing the system is very different, redoing the system will cause the loss of the data of the drive letter where the system is located, and Windows system restore is not necessary to reinstall the operating system, and will not destroy the data files under the premise that the system returns to the working state;

4. One-click restore: Now many operating system installation disks will come with one-click restore after completion, of course, we can also install one-click restore after the installation is completed, we have to back up the system before using one-click restore, if you don't have a backup, you can't use one-click restore, of course, if you don't have a one-click restore or no backup, this method can be passed, one-click restore is to reinstall the system, but it is integrated in the boot option.

1. The CPU is responsible for the operation of data, the memory is responsible for the data exchange of each component, the graphics card is responsible for the data processing and processing of the display part, and the motherboard is the channel for data flow and transportation, which is equivalent to the blood vessels and tendons of human beings.

2. The configuration is only relative, the accessories of the computer are updated too quickly, with the development of new technologies and new products, the accessories that are still high-end just now will not be able to keep up with the times in a few months.

3. Rationality: The most important thing is to configure according to your own needs. If it's just for typing, then the 586 era machine is enough. Playing games requires high-profile accessories such as CPUs, memory, graphics cards, monitors, and a stable motherboard.

CPU, the graphics card is relatively important. If it is a large-scale game, the requirements for the CPU and graphics card are relatively high, and the larger the core frequency and bit width of the i3 and i5 independent graphics cards, the better.
