Computer hardware upgrade The following is the current configuration of my computer, please give an

The CPU fluctuation should be a problem of your system, see if there are any background programs that are particularly using CPU resources. Use 360 Security Guard to clean up the system and optimize it.

The CPU you want to upgrade your computer can be replaced with a Q6600 quad-core of about 500, and the memory can also be considered for another 2G

The graphics card can be on the GT440 or HD6670 level graphics card, preferably on the GDDR5 video memory, more than 400.

Of course, this is my recommended upgrade, you can consider which ones to upgrade according to your application, for example, if you want the system to be more responsive, you can upgrade the CPU and memory, if you have limited funds, you can only upgrade the CPU. If you want to play games faster, you should mainly consider upgrading your graphics card.

How much budget do you have for an upgrade?

The main thing is to change the graphics card to a GT440, and if you have enough money, it would be good to change to a Core 2 E8 series or E7 series CPU

Your computer has little upgrade value, if you upgrade one or two hardware, other hardware will become a bottleneck for the performance of the new hardware, if you want to upgrade, you can directly buy a new host, and the optical drive can continue to be used.

The CPU is upgraded to quad-core, the graphics card needs to be at least 256M, and the hard disk is replaced with WD500G!

If you want to upgrade, it's enough to change the memory, you use 667, why don't you use 800, the speed of your board's front bus, it should be able to support 800, on the other hand, it's better to have no viruses, and what do you mean by slow? How fast is it to boot up? Running the program?

Game?

Since you said you don't play games, then this machine can fully cope with daily applications, have you redone the system? Even if it's a normal game, it's no problem.,,It is recommended that you redo it all over the system,

In fact, I don't know the size of the memory that affects the speed, there are many factors, if the landlord wants to upgrade within 1000, you can consider upgrading the memory to 2G, DDR2 800 It is estimated that your motherboard should not use DDR3 and then the graphics card does not need to be upgraded as you said, the hard disk is also a factor that affects the element, you can consider upgrading to a 500G 7200 rpm hard disk, there is no need to change it is estimated that it should be within 600 yuan.

Your computer is fine. No need to change. You don't know anything, just reinstall the system. It's so simple. Buy a ghostFully automatic installation.
