the computer itself, if there are problems with software, read
the software guide or contact the software supplier.

In the United Kingdom, and some other countries, AC
plugs contain fuses. If the fuse in the AC plug blows when
you turn on the computer, this may be caused by an AC

computer or its peripherals. Follow these steps:
1.
Turn off the computer and unplug all power cables and
unplug and disconnect all peripherals.
2.
If no cause is apparent, replace the blown fuse with one

for each peripheral in turn.

memory, and compares the actual configuration of the
