These are some symptoms that may be caused by the CPU.
Other components may also cause these same symptoms, check the general
diagnosis page for more information.
Whether a complete failure or an intermittent problem,
CPUs rarely fail. However, if it does fail, it is most commonly as a result
of some sort of electrical anomaly such as a power surge, brown out or
spilling a Pepsi on it and causing a short. A faulty CPU, memory or motherboard
may be impossible to distinguish. They each can cause some of the same
symptoms. The symptoms may repeat frequently or infrequently. The same
problem may repeat or you may get a variety of strange behaviors.
In most cases, the only way to know for sure if a CPU
is causing a problem is to replace it with one known to be working. Since
most people don't have spare CPUs sitting around, this solution is usually
a last resort. That is why in this table we try to steer you to other
causes that are more easily tested and ruled out before replacing the
CPU.
