I have an old Lenovo machine, there is no USB flash drive interface, and I like the chassis very muc

Use the riser card, I'll use it now, it's fast. Zhongguancun bought, 30 yuan. It is very suitable for old machines and old models, with 4 interfaces on the card, just plug it directly into the motherboard, and the system defaults.

You can add an interface to the maintenance place.

More than 90% of brand machines use small chassis and small motherboards, you just need to see if your original motherboard is with integrated display, with integrated display are small motherboards, brand machines will not be equipped with large chassis for small motherboards. You can also look at the 9 fixing screws of the motherboard, whether they are square or rectangular if they are connected into a line, and the small motherboard is square, and the 3 rows of screws from top to bottom are basically equidistant. The large motherboard is rectangular, and the distance between the 1 and 2 rows of screws is much shorter than the distance between 2 and 3, so you should be able to tell the difference.

If you buy a large case, you just need to ask directly if it supports a large board, in fact, the larger the computer case, the better, and the chassis above 200 is basically oversized and the materials are good.

Brand machines are generally small boards, few large boards, some are still special, and ordinary motherboards can't be used. Hey

Let's give you the size of a big board. x 。It is estimated that your chassis will not go up.

。。The standard ATX large plate size is 305 x 244 mm, and the standard ATX small and medium plate form is 244 x 244 mm. Find a tape measure to measure the size of the motherboard installed in the case, and compare it.

The power supply power of the front interface is relatively low, and it can only be used for mice and USB flash drives.

For large power consumers such as mobile hard disks, the power supply of the front interface is insufficient, so it often does not respond.

It's just a matter of getting to the back.

The main reason is that the front interface is connected from the motherboard with a wire, and sometimes because the line attenuates the current, it will cause insufficient power supply or unstable signal for the interface.

If you have an auxiliary power supply for your portable hard drive, it will be better to connect it to the auxiliary power supply.

Do you plug in the front or in the back, if not, do you have an interview after the plugging.

The chassis can be used, the hard disk and optical drive can also be used, and the others must be replaced.

The memory can only be replaced with DDR1 generation, and the motherboard can support as much as it wants, and it is best to fill the slot. The graphics card can only be changed to the AGP interface,AGP interface performance is relatively strong, there are sapphire X1600Pro AGP version,7600,7300,6800,6600,6200,And ATI X700,X800,X850,X1300 and so on have AGP version,But it is difficult to find,The second-hand market is not common,You can look at classic products such as FX5900 or 9800Pro,Hard disk does not know if it supports SATA, If you don't support it, you can only buy it on the second-hand market, and if you support it, it is estimated that it can only support about 200GB at most, which is more troublesome. If you don't upgrade your PC to the mid-to-high end of 2004, Half-Life 2 and DOOM Slayer 3 will still run very smoothly.

At present, the system of windows7 can also run smoothly, in addition to new games can not be played, watching movies on the Internet and office work are also good. Of course, to upgrade such an old computer, you must consider the power supply of the power supply, and the power supply of the brand and the key machine does not leave much room for power.

However, it is difficult to upgrade such an old computer, and upgrading the graphics card depends on the specifications of the AGP slot of the motherboard, and if it is AGP4X, it doesn't make much sense to upgrade to a new graphics card. If the budget is not very tight, it is better to buy another computer.

It's from 2003, except for the case and monitor, you don't have to change everything else.

First of all, there is a U disk to make a PE boot disk, and then enter the BIOS, set the U disk as the first boot, and directly jump out of the startup item list, select the U disk, and after entering the PE, there is a quick installation tool, you can directly use the quick installation tool to install win7 XP, if you want to have a ghost with the one-click recovery that comes with PE, ghost recovery.

Dear users, hello!

How to make a USB flash drive system disk and how to install the operating system on a USB flash drive I wish you a happy life, thank you!
