The computer will be stuck for two or three seconds as soon as it is carded, so it is most likely th

Are you sure it's a hardware issue? CPU or hard disk.

Computer lag is usually caused by drivers, startup items loading too much, software conflicts, and system problems.

2. Check whether there are some unwanted software or similar software installed --- the --- program --- uninstall the control panel, if there are more than one antivirus software or optimization software, you can uninstall it, and only keep one.

3. It is recommended to close some startup items: msconfig --- start --- running, and remove and cancel some unimportant startup items or "check" in front of third-party software programs.

4. In terms of system, it is recommended to use a pre-installed system or a pure version of the system to avoid the ghost version of the system compatibility and stability is not very good.

5. Computer configuration is also very important, if your computer configuration is relatively low, then it will cause a jamming situation, this situation can only upgrade the hardware with better performance, such as solid-state drive memory capacity, etc.

Reasons for computer lag:

1. There is a lot of computer garbage.

2. There is malware on the computer.

3. There is a problem with the computer's memory.

4. Computer hardware problems.

5. The software or driver is not compatible with the system.

1: Check whether the drivers of the computer motherboard, graphics card, and other hardware are installed correctly 2: Check whether there are high-occupying processes in the background of the system, and turn off 3:

Turn off the anti-virus software when playing games, some anti-virus software will scan the hard disk files from time to time to cause lag4: Pay attention to the CPU frequency, occupancy, and temperature when playing games, and if the CPU temperature is too high, it will automatically reduce the frequency to cause the game to freeze.

5: If you are playing a game, you should also check whether the input method is stuck, there are other reasons that cause Caton, generally due to insufficient memory or hard disk transfer speed can not keep up, frame drops are generally caused by high temperature, if you are air-cooled CPU and air-cooled chassis, it is recommended to match the air duct fan (2 air intake and 3 exhaust), if there is already a fan, it is recommended to check whether the air duct setting is unreasonable, the temperature of playing games will be relatively high, and it is easy to produce heat island effect resulting in frequency reduction causing game frame drops, Installing a game to monitor the temperature and fan speed can help you quickly identify the problem.

Try it out in the following ways to see if it can be alleviated.

1. Check the CPU and graphics card for heat dissipation, dust removal, oiling, or replace the fan.

Second, the power supply voltage is unstable, the power supply is insufficient, and the power supply with high quality and high power is replaced.

3. Clean up and defragment the disk.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter %temp%-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

7. Reduce the burden of memory, do not open too many programs. If you have too many documents open or too many programs running at the same time, you will not have enough memory to run other programs, so you should close the programs and windows you don't use at any time.

4. Upgrade the graphics card driver; Reduce resolution, color quality, refresh rate; Lower Hardware Acceleration - Desktop Properties - Settings - Advanced - Troubleshooting - Lower "Hardware Acceleration" to "None", and change to a higher graphics card if necessary.

5. Increase the physical memory to more than 1GB.

6. Set up virtual memory reasonably.

To play games, the virtual memory can be set to be larger, the partition where the virtual memory (page file) is stored, there must be enough space, the hard disk resources are insufficient, resulting in insufficient virtual memory, in a computer, it is enough to set up virtual memory in a partition, it is not necessary to set it in multiple partitions, and it can generally be set in the D partition near the installed system partition C.

7. Optimize your computer with Optimizer or Super Bunny.

Let's talk about what you can solve first.

1 Open the case to see if the capacitors on the graphics card are bulging, and whether there are any signs of scorching or short circuit in each part.

2 Check the CPU temperature and whether the fan is running normally.

3 Find a hard drive test software and scan it thoroughly.

I don't know how the computer reacts when you reinstall the system, whether it takes longer to install the system than before the blue screen, if so, it must be that the hardware is damaged.

When the computer is stuck, please pay attention to whether the flickering of the hard disk light is also regular.

The hard drive is most likely to be broken, if you can't be sure, find someone else's installation and take a look, and you will immediately know what the problem is.

If your hard drive is fine.

Then 100% is a virus.

You'd better get rid of all the hard drive stuff and rebuild the system, and if it's good, then it's the system, and if you still have this problem, it's the hard drive.

It is highly recommended that you use HDTune to scan the hard disk, generally this situation is very similar to the hard disk has logical bad sectors or physical bad sectors, the former can be repaired, the latter is troublesome.

Check for viruses first.

Then unplug the hardware and clean it with an eraser.

Also, see if the CPU fan is working properly.

Old machine, right? The machine is turned on to see if there is a capacitor packaged??

Poisoned Most of the time there is a problem with the system, reinstall the system!

1. If there are too many boot items, clean up the boot items.

2. If. There are too many software that are not commonly used, and the software that is not used is cleaned up.

3. If there is too much disk garbage, please clean up the cache and junk files on the disk.

4. If there is a problem with the driver, please use the random driver disk to install the driver, or reinstall the driver on the official website.

5. If the system is unstable, reinstall the operating system, and use the original system to install it.

6. If it is caused by overheating of the system hardware, replace the fan again, clean the dust, and recoat the heat dissipation silicone grease.

7. If the computer hardware configuration is too low or the hardware is problematic, you can only upgrade the computer configuration or replace the computer hardware.

8. If the network application is used, the current network connection application server will also cause such a problem, and the service area of the application can be solved by changing the service area of the application to the service area of the network operator currently connected or changing the network operator.

Basically, you're the reason for the hard drive.

It is best to wait at least 1 minute after booting up, as it requires a lot of hard drive speed to process system files and autoboot software after booting. After all, HDDs are still very slow.

If you can't bear it, you can consider adding an SSD.

This configuration is still very good, if you use the original system, slow for sure, because there are a bunch of applications installed that you don't use.

The hard drive has bad sectors or the power supply is unstable! It is recommended to change the power supply first!

It should be your graphics card problem It is recommended that you upgrade your graphics card.
