How to Run a full checkdisk
If your computer is acting funky, you may need to run a full Checkdisk or chkdsk. Chkdsk is a program that is included with your Windows operating system and is meant to find and diagnose any potential problems with your PC. Check disk will find errors in your boot sector and fix them, as well as point out any issues you may not be able to normally see.
It is relatively easy to find and run this program, and this tutorial will show you exactly how to do so. If your computer is still having trouble after you run this utility, you may need to take it to a pro but hopefully the chkdsk will save you the time and money.
