2.5. Reboot the PC 
Rebooting the PC refreshes the PC components and solves many problems. For example, a voltage transient (high voltage with smaller than 10-3 sec duration) may change the data in several bytes of RAM and your computer locks up. Rebooting can solve this problem. But it is not safe to immediately reboot in operating systems like Windows, NT and OS/2. At first the running applications should be closed. Then follow the steps suggested by the operating system developers to shut down.

2.6. Simplify the PC Configuration A 

PC normally has many driver programs and software for: 

 Sound card 

 Network card 

 Video card 

 Mouse 

 Screen saver 

 Printer 

 Scanner 

 Modem 

 Applications. 

Disabling some of the drivers and software you simplify the PC configuration. PC configuration means the list of active devices (hardware and software) in the PC. In DOS 6.xx, you can simplify the configuration as follows: 

 Reboot the PC. 

 When the message ‘Starting MS – DOS…” appears press . Then CONFIG.SYS and AUTOEXEC.BAT are skipped and your PC boots with simplified configuration. In Windows 95, you can simplify the configuration as follows: 

 Reboot the PC.  When the message ‘’Starting Windows…” appears press . 

 A menu appears. Select ‘Safe mode’ from the menu.
