If your PC or laptop is running slow, it may be time to try one of these 10 tips: from clearing out the dust to upgrading your memory or even reinstalling Windows
System a bit slow? Remember a time when it used to be faster?
Assuming the memories aren't wishful thinking, there's a bit you can do to clear out the cobwebs and get your computer running up to speed again, both on the hardware and the software side.
So before you pull the plug and buy a new PC, here are a few things you can do to possibly recover some lost speed.
1. Clear out the dust
Dust build-up over time can impede airflow, and airflow is vital for keeping system temperatures down. If your system overheats, it'll likely throttle its performance down to cope.
Cleaning out the dust is easier if you've got a desktop rather than a laptop — you can still clear the dust away from vents in the laptop, but be wary about opening it up to do a thorough clean, as depending on the vendor this may invalidate your warranty. If you're out of warranty, and you're confident of navigating the maze in most laptops, go for it.
The first step is to remove general dust from around the system. You could use a moist paper towel and cotton buds to get into harder-to-reach areas, but one of the best tools you can employ is a can of compressed air. Make sure to avoid vacuum cleaners — or at least getting overzealous with them. We've known people to have sucked capacitors right off the board. There are other issues with using a vacuum cleaner, too, as Brian Cooley of CNET News tells us:
...you might be tempted to stick a vacuum-cleaner hose inside and suck out the dust. Don't. Vacuums create static electricity, which is deadly to sensitive electronic components.
On that same note, don't be tempted to reverse the flow of your vacuum and blow the dust out of the computer. The dust inside a household vacuum can be harmful to your health, and you'll be spreading it all over your PC. Also, you risk blowing out sizable particles, which could physically damage internal components, especially if you're using a workshop vacuum. The beauty of compressed air is that it's clean and particle-free.
Before you start blasting, unplug your computer and take it outside — or at least to your garage. Now, working from the top down, blow out all that dust (put on a dust mask, unless you want a face full of grime) ... be sure to spray air in short bursts, keeping the can upright and the tube at least a couple of inches from the hardware.
Next, you'll want to get your fans and heatsinks clean. Cooley has some tips here, too:
Start by powering down your PC, removing the case lid and locating the various fans. Starting with the power supply, blow through the internal slits from inside the chassis, aiming so dust will exit the back.Now restart your PC, and while the fans are spinning, spray them once more — very briefly — to really send the dust flying.
If a fan continues grinding or ticking after you've cleaned it, there's a chance that you can always add extra lubrication. But if this is one step too far, you could always just replace it.
