Problems After the System Has Been Running Correctly
After the system hardware and software have been running correctly, new problems often indi- cate equipment failure. Go through the checklist below to see if the situation is one that may be easily corrected. If the problem recurs after you have checked and corrected all of these items, refer to the troubleshooting procedures (see Troubleshooting Procedure in this chapter).
______ If you are running the software from a diskette, try a new copy.
______ If you are running the software from a hard disk, try running it from a diskette. If the
software runs correctly, there may be a problem with the copy on the hard disk. Reinstall the software on the hard disk and try again. Make sure all the necessary files are installed.
______ Try clearing CMOS RAM and running Setup.
______ If the problems are intermittent, there may be a loose cable, dirt in the keyboard (if
keyboard input is incorrect), a marginal power supply, or other random component fail- ures.
______ A transient voltage spike, power outage, or brownout may have occurred. Symptoms of
voltage spikes include a flickering video display, unexpected system reboots, and lack of system response to user commands. Reload the software and try again.
______ Voltage spikes can occasionally cause the heads of the disk drive to contact the disk.
This can corrupt or destroy data files. If you are experiencing voltage spikes on the power line, install a surge suppressor between the power outlet and the system power cord.
______ Try reseating the memory module.
