- 1). Reboot the system if the computer locks up or appears to be acting strange. This clears the memory registers and resets all the programs that might still be running on some small level after you stopped them.
- 2). Open the Task List and end any programs that may still be running. Press "Ctrl-Alt-Del" simultaneously and windows will come up for any programs "not responding." Click on the "End Now" buttons for these.
- 3). Turn the computer off with the power switch if the computer is still frozen. Wait about a minute, turn it back on and let the computer run its disk scan.
- 4). Look over your cables and connections if the central processing unit (CPU) or monitor are dead. Make sure the power sockets they are plugged into are good. Check the pins in the cable connecting the CPU and monitor and make sure none of them are bent.
- 5). Make sure your anti-virus software is always updated. Run it frequently to check for any viruses you might pick up and remove any as quickly as possible.
- 6). Check the connections to the keyboard and mouse if either of them don't work. You might need to reboot if either have been disconnected. You can also run the Task List in the keyboard's case. Turn the power off and then back on after a few minutes if nothing else works.
- 7). Clean the keyboard and mouse regularly. Blow compressed air into the keyboard spaces and shake it upside down to remove anything in there. Remove the mouse's underside and ball, roll the ball along a clean cloth and remove particles from inside the mouse with tweezers.
- 8). Run the Scan disk if the computer starts up in "safe mode." Go to "Start-Programs-Accessories-System Tools-Scandisk and check the box that says "Automatically fix errors." Reboot after Scandisk is finished running.
- 9). Run the Disk Defragmenter if the Scandisk didn't solve the problem. This is in the same System Tools folder as the Scandisk. Ignore any message saying you don't need to defragment. Reboot again after the defragmenter is complete.
