Friends of NB playing computer play in and in!! High Score .

I understand that network issues can cause this, such as network lag, poor network speed, network congestion, and easy to not respond when loading content. Either that's your system.

I also encountered the same situation, with xpsp2 good, hit sp3 appeared just on the Internet good, on 5 to 10 minutes, the network is not gone, have to go offline, and then online, repeat a few times, I don't know if it's the Olympic network plug, or what, is it back to SP2?

If so, it may be a problem with the system, such as IE7 and SP3 will be stuck together, and it is recommended not to install some useless software, save resources while making the system simple and relaxed!! If it really doesn't work, you should try it with a different operating system!

Does lz have a firewall anti-virus software, it is possible that you have a new virus when you surf the Internet.

The reason why the machine is slow is very simple: one is the configuration, the second is the system, the third is the network speed, and the most powerful thing is the virus.

As you said, if it's not a virus, then it's probably a problem with the system installation, and you're not very clear, so I suggest you install or update the drivers of the graphics card and DX9

Problems with the system, to be redone. The online game card has a certain relationship with the speed of the Internet.

Isn't the memory too small?

Is it that the memory is not plugged in properly and the machine is not recognized.

Is it a system made by professionals? If there is really nothing left, there will be no such problems, which means that you have to change the graphics card, and I have also had this kind of problem in my family, so it's OK to buy a new graphics card.

My computer is in the same situation as yours It used to be super fast and now it's slow to death, I suggest you which Jinshan cleaning expert cleans it up, or if you don't have to do it, it's too much, the last reason is that the computer is aging, add memory or something.

You can't write in detail, what brand is in memory?

If it is a thousand purples and thousands of reds, then mourn in silence. Try another one!

It should be overheated.

Check the CPU fan and heatsink.

There is also a fan + heatsink for the graphics card.
