If the technician determines the CPU is not functional or repair will be too time
consuming, the CPU should be disassembled, saving usable parts to inventory, and
recycled.
Step 1 – Boot Test
CPU testing begins with turning on the system and checking its boot sequence.
Sometimes a computer will not properly boot up to the desktop. One of the first things to
do if the operating system doesn’t load properly is to go into the Bios screen (by pressing
F8 when prompted during the boot sequence) and reset the Bios and CMOS to their
default settings. This will often work to solve the basic boot problem.
If this does not work you might have to open up the computer and first check if
everything is connected properly and/or anything is missing. If everything checks OK try
using a boot disc start the computer. If you think you know the operating system type,
use boot disc for that OS, or if not you can use a DOS boot disc.

a) Listen for a single beep almost immediately after the machine is powered on. This
indicates that the
POST test is starting.
b) If there is no beep, RAM is probably missing or damaged. Install/replace RAM from
inventory. Make sure you use the same type of RAM to replace defective RAM; i.e.,
SIMMS must be used in pairs, DIMMS can be installed singularly. Reboot.
