I didn't turn off my PC properly and now it's extremely slow

[ranitbiswas100]

So I was on my PC one day and I was doing some work but somebody called me and I left my PC on for about 30 mins AFK and well I had built this PC couple of months ago and I thought it would go in sleep mode just like my laptop but when I came back it had turned off so I thought, OK so this might be a new feature in the PC that it automatically turns off after 20 - 30 mins so I turned off the switch of my power outlet but the next day when I tried to boot it up, everything was like 1000 times slower. Now I don't know whether my hard disk is damaged or not. If somebody knows what could have happens then please of me know and I would be very thankful if somebody could tell a solution. Thanks.

It is fine to shut off the computer with the power button. It has no effect on the computer. I have a one year old that is constantly shutting mine off, even when I am downloading something or working on projects.

Actually shutting down a computer improperly can cause problems:

Most likely corrupted file on the drive.
Run chkdsk on the disk to repair corrupted files.

Google it and you will find that this is not true any longer. It was true at one time, but not today.
