Welcome to Bleepingcomputer.
I have yet to publish my tutorial on how to safely clean out a computer for dust issues, but it is still on the drawing board at this moment.
One of the number one warnings I have in my tutorial is NOT to use a vacuum cleaner to clean out a computer.
I will tell you why, motherboards have special jumpers that allow for different settings based on how a computer is built and put together.
These jumpers are designed to make a connection between two pins that create a circuit, these jumpers are designed to be moved between 3 pins in some cases, where the jumper acts as a switch, pins 1 and 2 are off, pins 2 and 3 are on.
Sometimes the jumper just makes a connection between 2 pins only to be in the ON state and no pin to be in the OFF state.
These jumpers are coated with plastic, usually black in color and can be sucked off of the pins very easily by using a device such as a vacuum cleaner that has high suction, you'd actually have no clue it even happened until your done with the cleaning and you attempt to start your computer up again.
Besides the obvious of checking for a loose connector related to a power harness from the PSU, you now have to check your motherboard for a possible missing jumper your vacuum cleaner may have sucked up.
I do not suggest anyone use a vacuum cleaner for this reason and also because there is a risk for stray ESD which can zap your motherboard into being a paper weight.
