You are the computer technician for your company. A user contacts you and says that her computer shut down and won't turn on. Upon inspection, you determine that the Central Processing Unit (CPU) fan failed, causing the CPU to overheat and fail. You need to replace the CPU. What is the MOST important thing to keep in mind when replacing the CPU? Choose the best option(s) from those listed below.

a) The new CPU needs to be the same speed as the old one.
b) The new CPU needs to be faster than the old one.
c) The new CPU needs to be compatible with the computer's operating system.

Don't forget to replace the FAN too! Replacing the fan has to wait until the replacement CPU is determined. No sense buying the fan till you know it's compatible with the new CPU! :)

When replacing or upgrading only a CPU, you need to make sure that the new CPU is compatible with the existing motherboard. Most importantly, the new CPU must use the same package as the motherboard, and support the same bus speed. As well, it may also be necessary to upgrade (flash) the motherboard's BIOS to support the new CPU.

Correct Option(s):

d) The new CPU needs to be compatible with the motherboard.

Incorrect Option(s):

a) The new CPU needs to be the same speed as the old one. - The replacement CPU does not need to be the same speed as the failed CPU that it is replacing. However, it would be beneficial to use a replacement CPU that is at least as fast as the failed CPU. A slower CPU could result in a noticeable drop in system performance.
b) The new CPU needs to be faster than the old one. - The replacement CPU does not need to be faster than the failed CPU that it is replacing. However, it would be beneficial to use a replacement CPU that is faster than the failed CPU as it could noticeably increase system performance.
c) The new CPU needs to be compatible with the computer's operating system. - This should not be a concern unless you are upgrading from a single processor system to a multiple processor system. Your operating system should work fine with any single CPU that you choose for your system.
