Can t turn on can turn on super slow 15

There are many reasons for this.

Virus issues. There are too many installation files on the system disk, and there are too many temporary files on the system disk that have not been cleaned up (so don't always install the C disk with the installation files, and often clean up the temporary garbage).

Dual hard drives don't matter either. The first time the scan is done, it won't.

There is also a setting to check how long the disk settings wait.

It's simple: the antivirus is finished.

Take to clean up system junk and optimize the registry.

1. The PC chassis is full of dust, or the PC working environment is relatively humid, which will also cause abnormal operation. Dust removal in time.

2. CPU and graphics card heat dissipation problems, improve heat dissipation.

3. If there is a problem with the hard disk, scan to repair or replace the hard disk.

4. Driver problem: Reinstall and update the driver.

5. Illegal operation, the system cannot be executed.

6. Software damage and reinstallation of software; The software has bugs, patch or update to the latest version; The software is incompatible with the system: patch the software or try the compatibility mode of the system; There is a conflict between the software and the software If you have recently installed something new, try uninstalling it.

7. There is a problem with the system itself Sometimes the operating system itself will have bugs, so it is best to install the official update program in time and reinstall the system if necessary.

8. Virus problem anti-virus; Antivirus software conflicts with the system or software Since the antivirus software enters the underlying monitoring system, it may conflict with some software, so try uninstalling it.

Is it that your dual hard disks are not set up with a master-slave relationship?

The motherboard will also be like that.

1) It may be that there is a problem 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).

2) If this is always the case, Zen first soft and then hard, reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, don't install anything that doesn't fit (if you have any questions, please ask me).

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

3) In terms of hardware, such as whether there is a problem with the dust-resistant hard disk and memory, whether the temperature of the CPU and other hardware is high, if it is caused by hardware problems, it is recommended to overhaul it.

There are many reasons why the original chain attack is too slow to boot up, such as:

1. There are many startup items.

2. There are too many desktop files or insufficient system disk space.

3. There are too many disk fragments.

4. The virus has been dismantled; Shed uproar.

5. The computer has been shut down abnormally many times;

Solution: 1. Optimize the startup items and service items to speed up the startup speed 2. Use the software to clean up the junk files and registry generated in the computer every day;

3. Try to install some unnecessary software, games and plug-ins on the computer;

4. Develop a good habit of cleaning up garbage and anti-virus and sorting out computer disk fragments every day;

When you boot up, is it prompted to configure something, or is it an abnormal shutdown after booting up, in this case, the computer has a self-test, a little slow, if not, it may be that your computer configuration is too low, the system will be used for a long time, you can reinstall the system to try.
