Problems After The System Has Been Running Correctly

After the system hardware and software have been running correctly, many problems occur when the
computer configuration has been changed. Use the checklist below to try and correct the situation.
Problems at System Start-up
Error Messages are Displayed or Beep Codes Are Emitted
When you power on your computer, the BIOS (Basic Input Output System) performs a number of tasks
called the Power On Self Test (POST). These tasks test and initialise the hardware and then boot the
operating system from the hard disk drive.
Non Fatal Errors
If during the POST, errors occur that do not stop the boot process, then a message, similar to the following
display, may appear:
(Error Message Line 1)
(Error Message Line 2)
Press <F2> for Setup,<F1> to Boot
You should note the error and press the F1 key to resume the boot-up process, or F2 to enter the BIOS set-
up utility and correct the error.
Fatal Errors
Errors that prevent the boot process from continuing are communicated by either a series of audible beeps
(the BIOS cannot access the video card to display the message) or error messages.
Note:
fatal and non-fatal errors are usually related to hardware-related problems. If you recently
added a new hardware device, take a look at the section below and check that the new hardware has
been correctly installed (fully inserted in its respective slot, for instance). If this does not solve the
problem, please refer to
