Why does the computer get stuck every now and then?

The reason for computer lag is that some COOIKES are automatically downloaded when surfing the Internet, which are useless files that will affect the system running speed

And with the increase in software, there are more and more startup items. Reduced system disk space

Does not rule out the possibility of viruses

It may also be caused by running a certain program for a long time if the configuration is not good

My suggestion is (just It is recommended that your machine is still controlled by you)

Download a complete set of anti-virus software to regularly disinfect the virus,

Choose the optimization software suitable for your machine (use XP, 2000) WINDOWS Optimization Master, use VISTA Optimization Master for VISTA) to clear system junk files

Go to the website to download the registry cleaner (Baidu search), you can safely delete useless registry and the startup speed will be a qualitative leap

To reduce the entry of startup items, enter: msconfig at the runtime

Try to defragment the disk to free up disk space (in the startup program attachment system tool)

As for the card, see See my summary below

Insufficient memory will also cause the computer and graphics card to become obsolete

When the weather is hot, you need to pay attention to the heat dissipation of the chassis, otherwise the desktop computer will crash. You can consider directly removing the chassis shell. Remove (just a few screws). Laptops and the like should be placed in a ventilated place

If you are sure that there is no problem with the machine hardware, you can consider redoing the system and follow the instructions above to ensure that there is no major problem
