My hard drive light is always on, the CPU memory usage is not high, and the machine is very stuck

It means that the hard disk has been flowing with data (if it is not broken) For example, when copying things, the CPU occupies a low level, but the program is very slow, the hard disk can't be turned, the hard disk light has been flashing, go to check the hard disk data cable, antivirus in safe mode, no, format and redo the system, this situation has a greater chance of poisoning.

How much does the landlord's PF occupy? How much? How much memory?

Excluding too many junk files, viruses, Trojans, and software conflicts, the rest is that the memory is small but the virtual memory is too large, resulting in the hard disk constantly reading and writing when running large programs

There are many reasons for hardware, and what I have encountered is that the data cable is aging, and it is OK to replace one with my classmates.

The easiest thing is to format the system disk first, and then restore the system relatively quickly, and it won't get it**Optimize Master Standard Edition Clean up the registry Duplicate files Defragment Security 360 view processes and startup items Cancel the useless I don't know what is useless Just ban the insecure.

The problem may be very serious, it may be that the memory is small, it may be that there are many programs that run automatically after booting, it may be that it has been infected with a virus, it may be a Trojan horse, it may be that there is too much disk junk, it may be that there is a conflict in the software.

There are too many junk files that need to be cleaned up.

According to your description, it is basically a little more likely that the hard disk has a problem, so let's deal with it in the following way to see the effect.

1. The hard disk will be fragmented after long-term use, and the hard disk will be "defragmented".

2. Take a look at the space of the system disk (generally in the C disk), if it is too small, it will affect the speed of the system. Find a way to delete the disk space of the T system that is not used for nothing, and it is better to be greater than 10G.

3. Seeing that your memory is only 2G, this is generally the bottleneck of your system, and it is best to upgrade to 4G or more. Because after the 2G memory is used up, the virtual memory will be used, and the virtual memory is the space of the hard disk used, and the speed of this virtual memory is not comparable to the memory speed.

4. The above two steps of 2 and 3 can also be done one step is to reinstall a system first. If the system disk is really big, it is best to reinstall the system, and now the system disk is better to partition it larger. If your system disk is large, it is usually a problem that the memory is too small.

5. The worst may be that the hard disk is broken, and the above 4 steps are still very much a problem with the hard disk.

The hard drive has also been used for 3 years? The hard disk that took a long time was very stuck.

Format the hard disk and reinstall the system.

Clause.

1. Your computer has been used for several years, and the electronic components are aging;

Clause. 2. The system disk (USB flash drive) of the system you reinstall may already carry the virus, so even if you install the system many times, there will still be viruses;

Clause. 3. Maybe some of your larger software (PS, 3DMAX, etc.) will automatically run in the background when it is turned on, resulting in a large amount of memory occupation;

Clause. Fourth, if your system is win7 64-bit, it must be stuck, because your computer has been used for a few years, indicating that it has been a long time, win7 64-bit is a system that has only appeared in recent years, and it occupies about 600m of memory;

Clause. 5. Your C drive is too small and the computer generates a lot of heat;

In fact, your configuration is fully sufficient to run CF, but the following premise:

1. Whether the system has not been cleaned or reinstalled for too long, resulting in slow system operation 2. There are too many programs running in the background, such as PPS, Thunderbolt, etc.

Solution: 1. Reinstall the system, and only install the games and QQ to play.

2. Install 360 security guards, run C disk moving, computer cleaning and acceleration, etc. 3. Play CF There is a TP antivirus software in the background, which is TX to prevent plug-ins, you can go to the forum to find a startup program that does not contain TP.

Does it take a long time to install the system, like this, it may be a problem with the hard disk, sometimes the hard disk is detected without bad sectors, but it will be particularly slow when installing the system.

It may be a bad sector on the hard disk, check it with diskgenius, and use the slowest way to check.

Divide the bad sectors into a zone and then delete that partition to shield the bad sectors.

1。The computer is old, and like you said there is a problem with heat dissipation 2. It is recommended to clear cache, junk files.

3。The graphics card can be replaced. 128's is a bit small.

4。You're talking about playing CF, and the game itself has problems, with a lot of people and slow squeezing servers.

Hehe, adding to 2G has been solved. Then there's disk defragmentation.

Hehe, buddy, your computer is the same as my Dell. It's all old. It's time to retire. I ordered a very nice machine the other day. Let's change it.

Check the number of processes, and the number of processes can be optimized to 21 after the computer is started

Restore the system, and then the software will not be updated.

The hard disk light keeps flashing, indicating that the hard disk has been reading and writing operations. Reason:

1. The internal storage is small, and the memory is too small, so the hard disk has to keep entering the data exchange. Because of Chunliang, this hard drive has been flashing.

2. Infected with the virus, because the virus is infected, the virus is running, it is constantly infected, so it keeps reading and writing.

3. The Internet does not stop, and the temporary files are constantly processed and imitated, which will also cause the hard disk to read and write.
