My computer has become slower after booting up after the virus, since the system is installed, it is

Set up virtual memory.

There is a very large data exchange file in the hard disk, which is reserved by the system for virtual memory as a temporary storage place, which is often used by many applications, so the system needs to make a large amount of data access to the main memory frequently, so the speed of accessing this file constitutes a very important factor affecting the speed of the computer! Generally, Windows defaults to the system to manage the virtual memory, and it will automatically adjust the size of the swap file according to the needs of different programs, but such a large and small size will put an additional burden on the system and make the system run slower! For this reason, it is best to customize the minimum and maximum values of virtual memory to avoid frequent resizes.

To set the virtual memory, right-click on "My Computer" and select "Properties", and in the "Performance" dialog box in the "Advanced" option, set the "Virtual Memory".

Change your computer's virtual memory. Right-click on My Computer -Properties -Advanced -Performance -Settings -Advanced -Virtual Memory -Change -Custom Size. The small one is 766 and the large one is 1500 points, and the point OK is OK.

Another is to clean up the junk on your computer.

Mine too, as soon as the system is installed, it is slow, not adaptable, just use it for a while.

There are many reasons, one is that the search machine macro guess is old, and the motherboard and memory are small; Second, there are many junk files, the remaining space of the system disk is too small, and the file exchange cannot be opened; The third is that there are too many software installed and many plug-ins, which will affect the boot speed. If you have software such as 360 or Kingsoft Guard, it is recommended to clean up the missing jujube garbage, remove the plug-ins, and remove some unused software.

1There are many reasons why you start slowly.,It's not necessarily a virus.,You can use the optimization master or super rabbit to optimize it.,You can start up quickly If your system has any special failure problems,Generally, it can't be solved directly from the installation.,You might as well find a U disk to back up the driver.,Use the optimization master to install it.,And then install it after the grid.,So that the driver doesn't change.,System problems can also be solved.。

The way to overwrite and reinstall the operating system is: boot the computer with a boot floppy disk that can drive the optical drive, change the name in the windows folder (use the cd windows command to enter the windows folder under DOS, and then use the ren command to change the file name), and then enter the CD installation, in this process, please point the installation path to the folder where the original win98 was installed. If the overwrite reinstall still doesn't work, format the C drive and reinstall the operating system.

The way to format and reinstall the system is: please use the boot floppy disk that can drive the optical drive to start the computer (such a boot floppy disk can be installed in the control panel of the computer with win98 version 2 double-click the Add Delete program icon, and make it in the Make Startup Disk tab), select the first item, use the format c: command, format the C disk, and then type your optical drive drive letter (for example, the optical drive is an E disk, then type E:

Enter), and then type the setup command, after entering, it is the windows installation wizard, follow the wizard prompts step by step, at this time you had better prepare all the hardware drive disks, which hardware driver you need, just put which drive disk. The graphics card driver may not be installed until the system is installed, you can see if there is setup in the graphics card driver disk, if so, you can run it directly; If not, you need to right-click on the desktop to select properties, click the advanced button in the settings tab, click the change button in the adapter tab, and then follow the wizard prompts. In addition, please pay attention to the correspondence between all drivers and operating system versions, because many drivers provide drivers for different operating systems, be sure to choose the right one, mainly depending on the name of the folder.

If you suspect that your computer is poisoned, you will first check and kill the poison! Now the online antivirus effect is also good!

Poison has nothing to do with slow computer startup! You can go to Start Run and type msconfig!In the startup bar, close some programs that you don't think you need to start! If you can't, then you'll get it for you next optimizer!

If it is poisonous, it will be killed, and if it is not poisonous, it may be that there are too many fragments of the disk and need to be sorted out.

Check it with a Kasbox machine, if it really doesn't work, you can buy an XP image disc to restore it with ghost, and you can install a new system in a few minutes under normal circumstances! If there is a problem in the future, it will be faster to recover!

If you have a backup, you can restore it with ghost, and if you don't have it, install it again or delete some software that you don't use often.

Use Rising, it's very useful. If there's a backup.,It's OK to restore it with ghost.。

That's a good question. What do you tell us to say, you listen.

It's best to use antivirus software to kill the virus first, and you don't need to reinstall it.

The system has been garbage, or there are too many startup items, and the next 360 cleanup.

Probably there are too many startup items at boot, you can use some optimization software such as 360 to remove some startup items, and then clean up the registry and junk files will be better.

The computer has junk files that can be cleaned and can also be defragmented.

You reinstall the secondary system as much as possible using green software except for some drivers.

Then you can try that the speed will be fast.

Check if there are any programs that don't need to be turned on and run, just turn those off, clean up the garbage in the computer regularly, there are corresponding programs to help you solve it, like 360 security guards come with a boot assistant, and you can also help you clean up the garbage in the computer.

The slow use process can be checked for validation in several ways:

1.Use system optimization software such as "Rising Security Assistant" for system optimization2Check whether there is a resource-occupying process through System Explorer, and check whether it is normal after it ends3Check whether the driver is OK or update the driver.

4.At the same time, there are many weak and bad sectors in the hard disk, which may also affect the running speed, and can be detected or replaced in time with tools to prevent data loss.

If after the virus is ruled out, you redo the system slowly mostly because of the driver. It's best to upgrade the driver under it.
