Problems with installing the host 20, problems with the host mounting

DDR2 667 512 land costs about 150 pieces, other graphics cards cost 500 700, hard disks cost more than 500, optical drives cost 200 300, power supplies and others also cost some money, almost. Let me tell you, it's not the motherboard and CPU that are important, but the memory and the CPU are important, of which the memory is more important, because as long as you don't play games, the CPU usage is below 10%, including watching movies at the same time, chatting and watching web pages. But.

The memory is different, it generally takes up a lot of memory, especially when looking at web pages, which is almost all occupied. Your 512 memory will definitely not be able to play the performance it should have, you should add a memory to form a 1G dual channel. Finally, the price of the Core is not 500 900, you are talking about the Core 2, 1000 plus.

You can choose like this, a medium 965 motherboard (about 700) + core2 E4300CPU (about 800), and then 1G memory 320 (2G can also be) 650, now the 160G hard disk is 450 like this, and there is a graphics card about 700 (you can ask for 1650GT), so that counting the power supply and chassis, it is about 3500.

If you want 1G memory, it is in the early 3000s, if you really want to give full play to the strength of core2, you want 1G memory and a graphics card that can be pointed, otherwise it will be a waste of money to buy a good CPU, of course, if you consider the economy, you can ask for the CPU of E2140, which is now in the early 500s, and you can control it again3000

The landlord mainly did not consider that the power supply and the chassis together still need 250-400.

You use a 7300 soaring graphics card. It's only a few hundred quick bucks.

It doesn't take that much. 1G memory module DDR667 2 is more than 600 yuan.

To be exact. The unit price of the 667 memory module is 306 yuan.

2 is 612. There are about 700 left. You buy a graphics card as long as it supports multi-channel.

The video memory is a little larger. No problem. Everything else is integrated.

The other 1300 can come down is good, with the machine to see the whole, you you and the motherboard is so good, the graphics card can be second, the general graphics card has 600

If you choose a better graphics card, it is recommended to use a discrete graphics card! The rest doesn't matter! The optical drive is recommended to use benq, which is good and not expensive!

Good luck, brother!

If you have any questions, you can reply to me!

A graphics card is a good few thousand dollars.

Generally, the good ones should be more than 600.

Pins on the motherboard.

1.Power switch

The plug of this switch is two-pronged, and for easy identification by the user, one of the wires is generally indicated by yellow or black, while the other wire is usually white. This plug must be plugged in, or the computer will not be able to boot through the chassis panel. In addition, the power pin on the motherboard can be activated by shorting it directly.

The wiring plug of this switch is generally marked with power

SW, and the English abbreviation near the pins in the corresponding position on the motherboard is generally PWR and Power

sw、pwr

sw、pw、pw

SW or PS, etc.

2.Reset switch

The plug of the reset switch is also two-pronged, one of the wires is generally indicated in blue, and the other wire is white. Its function is to restart the computer without interruption of power, and it is often used when the computer suddenly crashes during operation. The plug of this switch is usually marked with RESET

SW, and the abbreviation near the pins at the corresponding position on the motherboard is generally RESET, RST, RS or RE, etc.

3.Power Lamp (power

LED) power lamp connection is also a two-pin plug, one of the wires is generally indicated by green, and the other wire is white. When the host power is turned on, the power light will come on. The plug of this switch is generally marked with power

The word LED, and the English abbreviation near the pins on the motherboard that should be positioned for wide bending dies is generally PW

led、power

led、pwr

LED or PLED and PLED- etc.

4.Hard Disk Lights (HDD

LED) hard disk light connection is also a two-pin plug, and the two wires are generally one red and one white. When the hard disk has read and write actions, the hard disk light will turn on. The plug of this switch is usually marked with HDD

The word LED, and the English abbreviation near the pins at the corresponding position on the motherboard is generally HDD

LED, HD or IDE LED and IDE LDE-, etc.

5.Speaker

The plug of this cable has four pins, but only two wires, and its color is generally one red and one black or one orange and one black, which is used by the speaker on the chassis when properly connected. The plug of this switch and the corresponding pin on the motherboard are generally marked with the word speaker nearby. Some computers will make a "beep" sound through the horn after normal startup, or when they cannot start normally, the corresponding alarm sound will be issued through the horn to help users solve the problem.

However, some motherboards already have speakers integrated into them, so you don't have to connect them to the speakers on the case.

So, don't you have to worry about the positive and negative polarity of these plugs and pins? Even if the power switch and reset switch are reversed, they can work normally and slowly without worrying about polarity. And the hard disk light (HDD

If you hear the hard disk running but the light is not on, you just need to reverse the plug. Other plugs are plugged in a similar way, if they don't work properly, they can be reversed.

Audio Interface: Look for the connector next to AAPF written on the motherboard.
