It took half an hour for my computer to start the self test again after the illegal shutdown 20

It is possible that viruses are checked and disinfected.

It's possible that a virus has invaded some of the files on your hard drive

Or you can detect whether there are bad sectors on the hard disk and use the hard disk bad sector detection software.

In the case of bad sectors, the self-test speed will also be too slow, and it is possible.

The self-test can't pass, if there is, fix it, and it's OK.

The configuration of the computer may not be very compatible.

I usually encounter this kind of problem in less than half an hour, at most it takes more than ten minutes to solve!

You can try to enter safe mode to change the settings, or try a different operating system, if there is still this kind of problem! That must be a computer problem!

Normal. I had a self-test that took 2 hours, the reason is that I was browsing ** when I turned off the computer illegally, and there were more than 500 **folders in my browsing**, there were more than 2g in total, and I had to check all these **files that could be wrong when I checked them all during the self-test, so the time was particularly long.

I guess you're in the same situation as me, right?

There should still be some problems, you can not let the computer check by itself.

When the illegal shutdown is restarted, the F8 goes in and selects the last correct configuration.

Entering the computer does not self-test.

One is that there are many fragments, and the other may be that the hard disk is going to be broken, try not to shut down illegally in the future, and back up the important data first.

Day. I've never heard of testing for more than 30 minutes!

You hold enter to start a point faster

There are too many pieces of debris on your computer, and there may be something wrong with your computer's hard drive.

It is advisable not to mess around in the future

If the self-test is not the C drive, transfer the contents of that disk, and then move it back again.

There are too many things, or they are from the NT series.

Hello, dear. We are glad to answer for you, the reasons and solutions for the computer to self-test for ten hours are as follows:1

Press the Del key on boot to enter the BIOS settings, turn off Detect Floppy Disk Drive, look for Drive A or Drive B, set them to "None" not to detect, or find the option on "Flopppy", set this option to "None" not to detect, and finally press F10 (Save & Exit)2Modify the system time: Open "Start" - "Run", enter " in the run input box, enter the "Group Policy" setting interface, then "Computer Configuration" - Windows Settings "--Security Settings" - Local Policy "--User Rights Assignment", find "Change System Time" and double-click to open it, then check your username and "OK".

Restart the computer, go to the BIOS settings, find the basic settings, and modify the time to the current time, press F10 to save and exit.

Redo the system, (before redoing the system, it's better to lower the hard disk and repartition it), it will be better.

Considering that the hard disk is slowed down and has bad sectors, you can replace the SSD.

After entering the system, the self-test is too long, so you have to do the system first. No, check the hard drive or other hardware!

If there is a restore software, remove the restore software and let it self-test.

If you don't restore the software, enter chkdsk x:f in cmd to detect and fix it.

x: represents your drive letter, just change it to yours.

I've had this kind of problem, first of all, please observe which disk is being scanned each time, running cmd (point"Get started"— then point"Run"—Enter cmd Enter).

Run chkdsk x: f directly (x refers to the name of the drive letter that is scanned every time, if the d drive is scanned every time, then enter chkdsk d: f directly).

--- your computer is running slowly, it feels like it's hard to use, and it's probably because the hard drive is close to the limit.
