It s been five or six years since I bought the computer, and the CPU memory and so on are not good,

The new CPU needs the support of the new motherboard, and five or six years ago it was just two cores, so update the motherboard to four cores.

Use Master Lu to take a screenshot before you know your configuration.

The memory does not know how much you are DDR is not recommended.

The graphics card also doesn't know if it's AGP or PCIe

You can use other software to look at the configuration.

Dear Lenovo users, hello!

Yes, the hard disk memory can be upgraded, there is no ** information here for the time being, it is recommended that you can consult the service station;

It is not supported even if it is changed. Hurry up! Let's get a new one. With your requirements, 1,500 can install a good one.

You can add one memory, as long as it is DDR2, the capacity and frequency do not matter (but if you want to use dual channels, you need to add one with the same specifications, or change to two of the same).

The graphics card can also be replaced, but because this machine is relatively old, it may only be possible to change to an older graphics card such as 9600GT, which can be bought for about three or four hundred yuan now.

Look at what you're used for.,If you don't play games, it's basically enough to upgrade like this.,It's barely enough to play games.,Including some large-scale games.。

If you want to move the memory, just change it to 2G800 and add 667 to the effect.

A more affordable upgrade solution is to buy a second-hand quad-core i5-3470 or i5-3570 online and replace the dual-core Pentium G860At the same time, buy a 120 240GB SSD to install the system, software, and games, and the original 500GB HDD as a warehouse disk.

After this upgrade, the performance of the whole machine is greatly improved.

The memory needs to be upgraded, generally the original 8GB is enough, and you can add another 4 8GB as appropriate. As for the graphics card, depending on your gaming needs, if you want to play large games, you can change to GTX750TI, GTX660, GTX960, GTX1050 and the like, or a card of the same grade, if you don't play large games, the original GT630 can be used improvised.

The B75 motherboard is not too old, and there is a lot of room for upgrades. The CPU can be up to i7 3770.

In fact, the G860 is also very good if you don't play games.

It is recommended to buy an SSD solid state drive with SATA interface, the transfer speed is several times that of a mechanical disk, and the speed of opening the program will be significantly accelerated after upgrading.

1230v3 on the CPU, add 16G memory, change the graphics card to RTX2070, you can consider adding a solid state. If you don't play games, you can not change the memory.

There is room for upgrading this configuration, it is recommended that the CPU be replaced with i5-3470, and then add an SSD hard disk to install the system and software, and there is absolutely no problem with general use, in case you still want to play games, the graphics card is replaced with a second-hand GTX960 or RX580

When the CPU usage rate is too high, due to the lack of CPU resources, it is often easy to have computer cards or no response, etc., in fact, they are considered from two aspects, one is from the software side, and the other is the hardware side. Since the hardware aspect can only be solved by hardware upgrades, so I won't introduce too much here, and the following is mainly for the system and software optimization methods to release CPU usage as much as possible.

1.Viral infection is ruled out.

If there is a virus or Trojan in the computer, the Trojan malicious program is likely to occupy a large number of CPU resources, especially some stubborn virus Trojans, which have been in a malicious loop activity, infecting all kinds of system files, and occupying a large number of CPU resources, this situation is easy to appear that the CPU usage rate is too high, even if the CPU is high, it can not withstand the repeated operation of a large number of malicious programs, so if you find that the CPU is used too high, you should first think about whether it is a virus in the computer, and it is recommended to carry out a comprehensive investigation and killing.

2.System optimization.

Once the virus infection has been ruled out, it is time to start with system optimization. It is recommended to optimize the startup item, and try to make the software that you don't need to use automatically start without booting, such as some ** software, bank security plug-ins, etc., which can be opened when needed, and there is no need to boot up. It is recommended to use the optimized acceleration function of 360 Security Guard.

3.Close unwanted program processes.

If you find that the CPU usage is high, you can go to Task Manager (CTRL+ALT+DEL) and close some programs and processes that are too CPU occupied and unneeded in Processes.

4.Optimize system services.

In the operating system, many system services are turned on by default, but some are very important and must be run, but some are not important, such as the computer does not have a printer, wireless network, etc., then you can completely turn off the printer function and wireless network system services, etc., which can also save system resources and save more resources for the CPU.

Hello, according to your computer configuration, it is recommended that if you want to expand the memory to 4G, it is recommended to use dual-channel technology, which needs to be the same as the original DDR III 1333 particles. The memory bandwidth speed will be doubled. To upgrade the graphics card, it is recommended to change the power supply to a rated 300W or more.

If you do not change the power supply, it is recommended to use GT240 DDR5

7850 first check your chassis size allowed? You used to be a small graphics card, is there any pressure to change to a larger size of space?

You don't have to change the CPU, although it is the first generation i3, but the performance is passable. There is no need to upgrade.

You can also see the shortcomings, it is the graphics card. It's good to upgrade the graphics card and pay attention to the size. It is recommended that you upgrade to GTX650Ti, HD 7770 level. No matter how high the feeling CPU is, it has to be replaced.

Hello! This computer CPU is average! But it doesn't affect you to change your memory and graphics card! Thank you!

It's okay to upgrade your computer like this, and the idea is right. But it's a pity that yours is a brand machine, and the power supply of a brand machine is generally only about 200W. So, if you want to upgrade the graphics card, it is recommended to change the power supply to a rated 300W or more.

If you don't change the power supply, it is recommended to use the GT240 DDR5 and the HD7750 if the performance requirements are good, which have very low power consumption.

This motherboard should support either a 754 or 939 processor. The details can be viewed with cpu-z.

The best processor with 754 interface or 939 interface is only Athlon's single-core 3200+****It seems to be about 20 yuan, and it is sold on the Internet.

However, there is only a slight improvement in performance, which may not be noticeable.

Memory 1G DDR4002 hand is also very cheap, you can get it for dozens of yuan. However, you must choose the same brand and frequency, DDR compatibility is very average, not as casual as the current DDR2 DDR3.

The rest will be used.

In fact, if you want to change it, you can change it all, it's been 7 years, it's time to let go,
