Troubleshooting and Replacing CPU Sockets

It can get frustrating working on deadlines on your Intel Core 2 Q9400 machine especially if it is unreliable. Even worse when right in the middle of your job, your Core 2 system shuts down making you lose all your unsaved work. Such situations normally reflect the condition of your CPU.

How will I know when to replace my Core 2 Quad processor?

Most, if not all CPUs have a long lifespan. Manufacturers offer approximately 100,000 hours of life estimated to last about 10 years. By this time, you will notice a number of problems.

  • Shut-down - Computer turns on, but it immediately turns off.
  • No POST - Your computer powers on, but does not do a power-on-self-test (POST)
  • No beep - Your Quad Core machine powers on, but does not beep.
  • OS is not loading - Your computer turns on but will not load its operating system.
  • Speeding fan - Your machine turns on, and its fans run very fast.
  • Freezing screen - The screen on your monitor freezes after being on for a couple of minutes.
  • Blue screen of death - This happens when your screen turns blue.
  • Capacitors - Check whether the capacitors on your motherboard are leaking or bulging.

Can I replace my Core 2 Duo with a Xeon CPU?

Unlike the traditional single-core processors that used to be, CPUs today come in different kinds depending on the number of chips per core. These are among others:

  • Dual-core
  • Triple-core
  • Quad-core

One of the differences between the various types of CPUs to choose from is the type of socket used for each. A socket is one of the mechanical components of a CPU slot. Its functions are:

  • To prototype circuits
  • To allow replacement of your defective CPUs without having to solder it.

With that in mind, it's important to understand the difference in your processors and what it does before making your purchase.

Which socket will my Core 2 Quad require for replacement?

There are many types of sockets available for various CPUs. Installing one depends on the type of processor you have, the motherboard, CPU cooler, and the case on your system.

The most commonly used one is the LGA775 also referred to as Socket T. The LGA775 is compatible with several CPUs from Intel. Let's take a look at them:

  • Intel Pentium D
  • Intel Pentium 4
  • Intel Xeon
  • Intel Core 2 Duo
  • Intel Core 2 Quad
  • Intel Pentium XE
  • Intel Celeron
  • Intel Celeron D

These CPUs can also use the LGA 771 socket with the addition of an adapter and a little modification. To prevent damage on your motherboard during installation, use minimal pressure during installation.
