9. PROBLEM: Computer will not restart. SOLUTION (S): 1.Turn the computer off and try to restart again. 2.Use a “boot disk” to restart the computer and check your hard drive. (If the computer restarts but you cannot open the C: drive, the hard drive may be damaged).

10. PROBLEM: Computer still will not restart- the screen is blank; there is no sound. 1.Make sure the power cable is securely plugged into the outlet or surge protector. 2.Make sure the power cable is secure in the back of the computer. 3.Plug another electrical device in to the outlet to see if it is getting electrical current. 4.Use the power cable on another computer to make sure it is working.

17. PROBLEM: A Message Appears on the Monitor That Says: File not found. 1.You typed the file name incorrectly. 2.You entered spaces or too many letters in the file name; 3.The file is stored in another location-go to the MY COMPUTER icon and open the C: drive- then open folders to find the file name. 4.Click on the SEARCH option-type a word that can be found in the file.
