Processor upgrade – In upgrading a processor, the very common error is to buy a processor that is not compatible with your motherboard.  You might want to upgrade your processor to a core 2 quad but eventually, your motherboard can only support dual core processors. In upgrading your motherboard, make sure that you’ll be buying the processor that is compatible with your motherboard so that you won’t waste your money. When handling processors, always be careful because if one of the pins in the processor bends or breaks, it’s a big problem.

Lastly, before installing your new processor, make sure to put some thermal compound between the processor and the heat sink. This will help your processor to be cooler because of proper heat dissipation. Make sure that the thermal compound just thin and applied evenly. Improper application of thermal compound can cause overheating. Monitor your CPU’s temperature especially when your processor is newly installed.

Heat sink fan upgrade – This upgrade is normally done by gamers to avoid CPU overheating. The common mistake when upgrading heat sink fans is that when you’ve bought a different socket which means that it won’t fit in your processor. Another mistake is to buy a high end heat sink fan without measuring if it will fit in your pc case or not. I’ve seen many computers who upgraded their heat sink fans and can’t close their side casing anymore because the heat sink fan is so big. Before upgrading your heat sink fan, make sure that your pc case is big enough to handle high end heat sink fans.

Motherboard upgrade – The motherboard is commonly replaced when it is defective. The common problem when you change your motherboard is the compatibility of your old components. You might buy a new motherboard to replace your old one but it is possible that your new motherboard is not compatible with your old processor and RAM. Always make sure that your new motherboard can still handle your old processor and RAM for you to be able to use it.  

In upgrading your system, you must never forget that when you upgrade or add devices, power requirement increases. This means that it might be possible that your power supply is not enough to support your devices. You might need to upgrade your power supply to avoid power shortage which can result to various problems.

Always remember that before upgrading anything, make sure to double check its compatibility with the upgrade that you want to apply. This will help you minimize problems and errors in upgrading.
