Desk Top Computer Dust Problems

We all have the same problem with dust in our pc's.

If you has a case the has space for a side fan(on the side panel), simply turn the fan around that it blows air ou almost like a normal fan.

The will cause the pc to still collect dust via the power supply, however the other fan will help to get it out again.

Just be carefull not to use the systems own fans, this may cause heating problems.

My acer 5520 shutss of within 3 seconds I cant enter anything or go into anything


Can you turn it on after it has cooled down for an hour or so? If that is the case, you should remove dust from the fan. To do that, you need a screwdriver to open the case that is placed right over the fan. Then you should unscrew the fan to lift it and remove any dust in and around it.

casing getting hot, fan going mad then slowing down


Have you ever removed the side panel and cleaned out the dust from inside the computer case?

If your fans or air inlets get clogged up with dust then your machine will run very hot and could eventually shut down or cause permanent damage.

Unplug all the cables from the back of your pc, and remove the 2 screws from the back panel that secure the side panel. Then just pull back on the side panel and it will pop off.

Clean out all the dust from inside the case. You can use a vacuum hose but don't bang into anything with it. Also use a small clean paint brush to lightly brush the dust off of the fan blades and the CPU heatsink and around the power supply air vents. You can also use a can of compressed air if you have it to dislodge the dust and then **** it up with the vacuum.

Good luck and please comment back and RATE if this was helpful.

After about minutes of running the computer just


this sounds like an overheating problem.

First thing i would check would be the CPU fan. you will have to remove the side access panel on the case to check this.
If the CPU cooling fan is covered in dust, and the spaces between the cooling fins on the heatsink (right underneath the CPU fan) are clogged with dust. it would cause this problem.
there is also a fan at the back of the computer inside the power supply that can get clogged with dust, and may possibly overheating and shutting off. if you look in the back of your computer and find where the power cord plugs in, the power supply cooling fan is right around there as well.

If there is a good buildup of dust, it would be best to have your computer professionally cleaned. Using a vaccum cleaner is not a good idea unless you are familiar with procedures of working with static sensitive components.

hope this helps

I would suggest opening the side of the case and removing any dust or debris thoroughly with a can of compressed air.

Often times this is caused simply by dust.

After this. I would make sure all your connections are good, and start the machine with the side panel off of the case. Notice if any fans are making a "whining" or "hissing" noise. Also, if any fans are spinning slowly, or alternating speed dramatically enough to actually see the change.

If any of these issues are present I would suggest replacing the fan. A local computer shop would have one cheapest, but if you need to large corp. electronic stores may carry them.

If this information was helpful please rate.

my hard drive fan is always on its driving me mad ! please help ?


Buy a can of compressed air, open up your computer case (usually a panel on the left side slides off with two screws on the back) and blow all the dirt and dust out. Also make sure that there is adequate ventilation around the tower. 4 inches on each side and 6 inches on the back should be good.
