I just took the pannel of the side of my computer and there was mounds of dust and i tried to clear most of it. :thumbsup: Will this make a big effect to the performance?

Yes, but did you get it all? Especially in the CPU's heatsink
Cleaning the PC interior

Just a note that if you remove the heatsink, you will have to re-apply the thermal compound

The biggest concern with dust build-up in a computer isn't so much performance as it is HEAT. The more dust builds up in there, the more it insulates the heat and interferes with airflow. Of course, when things start running too hot in there, you have the usual suspects of the computer freezing up, abruptly restarting itself or receiving the dreaded BSOD.

You're using cans of compressed air to clean it out, right? Be sure when you use the can for the first time (or after a while) to point it away from the computer up in the air or wherever. There's always a little bit of liquid in the initial use. NEVER blow out dust with your mouth, that's introducing moisture to electronic components, a big no-no.

Garmanma is right about cleaning out the CPU's HSF. I personally use a q-tip, but make sure there's no wildly loose strands of cotton that could fly off. If you take off the HSF, dip a q-tip in at least 91% rubbing alcohol to clean off the old paste. I had no trouble doing this.

Oh yeah, if you DO take off the HSF, let your computer run for a solid 10 minutes before taking it off so it's easy to remove and not sticking.

Using compressed air cans would be good.

Use compressed air cans...just don't tip the can since the liquid would come out. Or, if you're more hardcore, use an air compressor. :thumbsup:

You will get a quick blast of air, but then it will quit
I do use a oil-less compressor, but it's regulated down quite a bit.
Depending on your setup, you can leave the heatsink in place and just remove the fan, and use a paint brush to get in between the fins

Some cans of compressed air have attachable nozzles that can bend. That's what I use.

hi,,, try not to use a cylinder air compressor as these build up lots of moisture after use and if not drained correctly then next time you use it it could hose down your pc.

Hey saracen619,

It may not be entirely smart or hi-tech but I use a standard hoover with the extension hose and a little USB hoover for the fiddly bits. It's not blown up yet and I've done it loads of times. I'm sure others will have reasons not to do this but it works for me.

The problem with that, though I've only read about it, is the build-up of static electricity. Where, if discharge near the CPU, can destroy it

The air moving through the tube of the vacuum isn't the problem, it's the particles striking the inside of the tube which creates the static electricity. Because of that, a vacuum is a great static electricity generator.

If you are very careful not to touch the nozzle of the vacuum to any of the parts of the computer you can use it without problems. I've used one held just outside of the case so that when I blew it out I could contain at least some of the dust flying out.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Hey dc3,

I didn't know that but it may explain why I've not blown my system to bits. My hoovers got a plastic nozzle and the USB version is basically a flexible rubber pipe. I can't see either one giving off much static but I agree it's probably not the smartest choice.

I don't think the heat in your computer is that bad, that you would need compressors i think your computers internal fan will do for cooling. just clean it up a bit.
