Troubleshooting CPUs

PUs are pretty robust beasts and rarely have problems after they’re installed.

You’re most likely to encounter problems with installation, although heat

issues can become a big deal at a later time.

Installation Problems

Look (and listen) for the following signs of installation problems:

•

It’s normal for the CPU fan speed to fluctuate, but if the fan doesn’t

spin at all for more than 5 seconds or so, turn the system off and make

sure that the fan is plugged in correctly.

•

If the fan is spinning but the PC doesn’t boot, make certain that any

jumpers governing speed or voltage are set correctly.

•

If, after a few minutes, you hear a loud alarm, this is an indication that

the system is overheating. Turn it off immediately and check your fan

installation to make sure you’ve got good CPU/heatsink contact and

that the fan is functioning properly.

•

If the system does not boot and the fan does not spin, check to ensure

that the CPU is seated properly and that no other components or

cables have been unseated or disturbed.

Heat Issues

Excessive heat can cause serious damage to your CPU and to any other compo

nents inside your computer. The fan on the CPU pushes hot air away from the

CPU and into the case; case fans and power supply fans push hot air out the back

of the case. Front case fans pull cool air into the case.

The problems start with ribbon cables that impede airflow and clogged or

dying fans. Incautious drive installation can leave ribbon cables strewn all over

the case (Figure 5.15). Dirt, dust, hair, and age can slow down fans to the point

where they can’t do the job.

The warning signs will be there: spontaneous reboots, especially on warmer

days or with the heat blasting in winter time; occasional alarms from the tinny

PC speaker; lockups; excessively loud fans. The fix is easy. Check the fans and

replace when necessary.
