Step1
My Computer will show you all of your available drives on your computer.
The first thing you need to do is to open My Computer and go to the Windows directory.
a. In the My Computer window, double click on the C: drive on your computer. If you have not renamed the C: drive, it will show as Local Disk (C:).
b. Double click on the Windows directory.
c. Scroll down and double click on the Temp directory.
d. Delete all of the files in the Temp directory. If you are not comfortable or you are unsure of what directory you are in, you can skip this step and move on to Step 2 of this article.
Step2
After you have deleted the Temp files, it is best to empty the Recycle Bin. If you have files in the Recycle Bin that you are not ready to fully remove from your computer, it is best to go through the Recycle Bin and delete all the files but those you want to save.
Step3
Local Disk (C:) Properties Window
The next step is to run Check Disk on your computer. Running Check Disk starts from the My Computer window. In the My Computer window, right click on your C: drive. Again if you have not renamed it, it will show as Local Disk (C:).
In the short cut menu, click on Properties. This will bring up the Local Disk (C:) Properties window. Click on the Tools tab.
Step4
Check Disk Dialog Box
In the Local Disk (C:) Properties window from Step 3, click on the Check Now... button. This will bring up the dialog box Check Disk Local Disk (C:).
In the Check Disk dialog box you will find two check boxes. To do a quick check of the hard drive for minor errors, do not click on either of the boxes. Simply click on the Start button and you have run Check Disk.
If this does not correct the issues that you are having with your computer, continue to Step 5.
Step5
Check Disk Dialog Box Options
If you are having problems opening a file or files and possibly experiencing other slowness issues, check both boxes as shown in the picture and click on the Start button.
The options you are selecting are:
Automatically fix file system errors
Scan for and attempt recovery of bad sectors
Most of the time this will correct any hard drive issues that your computer may be having. This will bring back the use of all of your files and increase the operating speed of your computer.
