Problems After The System Has Been Running Correctly - NEC Express 5800 TM700 User Manual

Problems After the System Has Been Running
Correctly
After the system hardware and software have been running correctly, problems can
indicate equipment failure. Use the checklist below to try and correct the situation.
If the problem recurs after you have checked these items, refer to the Troubleshooting
Guide section earlier in this chapter.
If you are running software from a diskette or CD, try using a new copy.
If you are running software from a hard disk drive, make sure that all of the neces-
sary files are installed. There may be a problem with the copy on the hard disk.
Reinstall the software on the hard disk and try again.
If problems appear intermittently, there may be a loose cable, dirt in the keyboard
(if keyboard input is incorrect), or other random component failures.
A transient voltage spike, power cut, or brownout may have occurred. Symptoms
of voltage spikes include a flickering video display, unexpected system reboots,
and the system not responding to user commands. If necessary, exit any open appli-
cations and shut down your system power. Reboot the system, then load the soft-
ware 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 AC electrical power line, install an uninterruptible power supply between
the power outlet and the system's power cord.
