What is the reason why the boot starts quickly and then slow?

Recently, I have encountered several such things, almost all of which are caused by poor heat dissipation of the computer, and whether yours is also the reason. Please clean the dust from the CPU and graphics card heatsink.

The system will be used for a long time will have a lot of junk files, system vulnerabilities, software installation also affects the boot speed, it is recommended that software and games do not put in the system disk, often clean up the system garbage, close unnecessary startup items.

Generally, playing games or operating for too long will cause slow shutdown or crash, if so, press the shutdown button to turn off. The other is what software, plug-ins, drivers, and patches have been upgraded before the failure, and if there are them.

Clean up the trash! Then if you install more and more software, the C drive is less and less free, and the boot will be slow! Optimize it more!

Maybe an unnecessary service item was activated! Also clean up regularly!

Start the service item at boot and optimize it, it will be better.

1) Slow boot or stuck:

First soft and then hard, such problems are caused by software conflicts, inappropriate drivers, and system problems, you can restore the system, or not reinstall the operating system, don't install software, patches, drivers, etc., to see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, don't install them if you find something that isn't suitable (if it's a hardware problem, please overhaul it, such as hard disk, etc.).

2) It may be that there is something wrong with the disk, please fix it (fix it for each disk or only fix C).

Built-in disk repair method:

The specific steps are as follows: select the drive letter in my computer, right-click to select the properties, select "Tools Start Checking" in the pop-up drive properties window, and select "Automatically repair file system errors" and "Scan and recover bad sectors", and then click Start, the scanning time will vary depending on the disk capacity and scanning options (after doing it according to the above method, a box will pop up, the point is, repair after automatic shutdown at boot, win7 select the disk check button according to the plan).

Bad sectors on the hard drive will lead to corruption or loss of computer system files, computer failure to boot or freeze. Hard disk bad sectors can be repaired using NDD Disk Utility or Scandisk.

If the fault persists, please restore the system or reinstall it (it is still not possible to format the hard disk and repartition and reinstall it, if it doesn't work, you will have to replace the hard disk, or overhaul it).

Junk caused by you can use antivirus software to remove the junk or just change the system After changing the system, the speed of the computer becomes significantly faster.
