Why is it that as soon as my computer is turned on, there is only half of the physical memory left?

Your memory is only 512, and it's normal to have half of it left after entering the XP system.

In addition to physical memory, there is also a virtual memory, which is to set aside a space on the hard disk for memory, which is much slower than physical memory. Physical memory and virtual memory are used at the same time, not to say that the physical memory is all used up before using virtual memory, in the past, when the 256 memory was used, the XP system put a lot of things in the virtual memory, you are now 512MB memory, it can only be said that the XP system puts more things in the physical memory, and the virtual memory used is reduced, so the computer will run faster than when the 256MB memory.

There are too many boot startup items. Like Kaba and the like. Originally, the XP system takes up memory, and Vista takes up even more. You just turned it on, and the video memory doesn't use much, so you can't see the problem when you change it from 64M to 32M.

You try shutting down some processes or shutting down some startups.

Type msconfig in Start-Run and turn off some startup items (remove the checkmark) in Startup. I turned everything off, except for ctfmon, which was on.

The amount of memory used is not directly related to the number of processes, for example, if your system is beautified by beautification software, or the LAN function of the system is turned on, then it is normal to occupy more than 200MB of memory. My system is pure version + gold mountain set + 360Boot also uses up 230MB of memory.

You can also calculate that the new system installed will have 18 processes, which will occupy a total of about 170MB of memoryThe Kaspersky you use will take up about 30MB, and there are other small programs, which are about 220. 448 must have half of the memory left.

It is recommended that you reinstall the system, which is not used to the system.

This problem occurs if you are adding a memory module for a long time.

Then it's computer poisoning or you have a lot of software.

There are a lot of things in the startup items The startup items are the things that start some programs at boot.

If the XP boot memory usage exceeds 200M, there may be a problem.

Yes, the memory is a bit low, so it's normal, there's nothing wrong with that.

Normal Your XP system and your Kaba are taking up memory only.

This is normal, and half of it is usually used.

The main thing is that you have installed too much software, and when you start win, you have to detect that everything in the boot options of the computer is taking up memory. After executing another program, the software closes but the memory is not completely emptied, and it takes a long time.

There is a lot of junk in the memory, which needs to be cleaned up with optimization software. You can cancel some unnecessary software startup options such as: QQ, Firewall, Untypo, etc.

If you want to open it again after entering the computer win, you can often clean up the memory, you can let the memory sorting software run on boot, and it's good to tidy up.

There may be a system software conflict, or there is a virus, it should not be so much, it is recommended to use 360 to remove some uncommonly used boot software, optimize it and see, if the memory usage is still too high, it is recommended to reinstall or ask a professional to check and kill.

It's normal, system occupancy, various services, and apps that are booted up.

When adding memory, it is recommended to take the dual-channel mode to carry out, because the role of dual-channel memory modules can increase the bandwidth of memory modules, and because it is the same brand, the same batch, and the same frequency, the incompatibility is very low, and in the process of use, the computer will not be unknown Caton because of the differences between the two memory modules. It is best that 8+8 plays their role the most, although 8+16 is dual-channel, but many times it will not be able to play the remaining 8g and there will be incompatibility!

This is normal. The computer's operating system determines the memory usage based on the actual situation and ensures reasonable use by allocating virtual memory with the disk. The mechanism is like this, as long as it runs smoothly, it means that it is normal.

You look at the properties of the computer in the hardware configuration is not an integrated graphics card, at least half of the memory should be allocated to it for video memory, laptops usually lack memory is the reason.

Poor contact solution of memory module: If the memory module is faulty, there will generally be a beep alarm sound, if there is an alarm sound, you open the case and take out the memory module to clean it with anhydrous alcohol or an eraser, re-plug it once or try to change the slot, be careful not to plug the memory module upside down.

Disassemble the main chassis, remove the memory module and wipe it with alcohol, wipe the ash clean, and plug the memory module back into the motherboard. If it still doesn't work, it may be that the memory module is damaged, and you can try again with a new one.

Memory is a dynamic storage and low usage is actually a good thing.

1. There are many background programs running, too much system cache garbage, too many services started by the system, too many self-starting programs, and the computer is attacked by viruses, etc., which may cause a lot of memory to be used.

The following methods can be improved:

1. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

2. Disable redundant service components. Right-click "My Computer" --"Management" --Services > Applications "--Services", and set the unwanted services to disabled or manual in the right pane.

3. Close Dr. Watson, click "Start" -- "Run" -- enter the "drwtsn32" command to open the Dr. Watson window, only keep the "Dump All Thread Context" option, and cancel the checkmark in front of the option.

4. Delete unused programs and software.

5. Antivirus, 360 Security Guard or Super Rabbit Repair IE, use 360 Security Guard to clean up bad review software and fix vulnerabilities.

6. Clean up and defragment disks.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter %temp%-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

1 To the brother upstairs, I was truly speechless.

2 win7 32 and 64-bit boot occupy memory really no difference, okay?,It's a look at it that hasn't been installed.,I think 64-bit must be big.。

3 The owner of the floor doesn't have to be entangled.,It's all normal.,win7 win8 automatic start process takes up memory1,7G。

4 Generally, 4G memory is full of difficulty for these two systems, I do computer maintenance, assembly of this piece, so many years, the computer has seen a lot, basically like this.

5 Now 8G a memory module, it is only 3,400 yuan, add one, the effect is obviously different6 I see that the landlord's CPU is basically no pressure, and it should be no problem to add root memory To sum up, pure hand-played, if it helps, please adopt the answer!!

There are many system services, and the system is optimized under 360. In addition, it is 64 bits, if it is high in itself, it needs 8g.

Generally, the memory is too small, it is recommended to increase the memory, but if it doesn't work, just redo the system.

There is a virus running, look inside the process and see what it should show.

Changing to XP solves everything!!

Scenario 1:

For example, if the installed memory is greater than 3G, a 32-bit system is installed. Since a 32-bit system cannot use more than that, installing a 64-bit system can solve the problem.

Scenario 2: If you are using an integrated graphics card, the integrated graphics card will occupy a portion of the memory and use it as video memory. There are many solutions, use a discrete graphics card, or enter the BIOS to reduce the memory usage.

Situation 3: 1. First of all, start - run - msconfig and run the system configuration.

2. Under the "Boot" option in the system configuration, select the current system and click the "Advanced Options" button.

3. Check to see if the "Maximum Memory" option is selected, and the memory filled in is less than the memory you actually installed. If it matches what I said, then remove the checkbox, or change the maximum memory value to the memory value you actually installed.

You can turn off the virtual memory, and the system will usually set the hard disk space of the double memory to the virtual memory. You already have 2G of RAM, which can run without virtual memory, and when you turn off the virtual memory, the system will run faster, and the memory access speed is much faster than that of the hard disk! So you turn off the virtual memory, which can increase the memory usage and make the computer run faster!

It can be solved with the help of 360 security guard, as shown in the figure below to open the 360 security guard pilot version:
