SLOW COMPUTER? How to Speed up your PC

SLOW COMPUTER? How to Speed up your PC

Speeding up slow PCs is one of the most common jobs we get in our Penrith computer repair shop.  there are a few things you can check to help with your slow PC  which we've outlined here.

Ctrl+shift+Esc – Launch the Task Manager

Your computer is always running tasks in the background, its core processes wheel away even when it looks idle.  Programs check for updates, antivirus software pokes around for odd behaviour and it will even try to second guess what you might do next and get things ready for you.  Things are always going on. In a healthy PC this is not a problem.  A modern computer has loads of Processing power and Memory for every day tasks.  Sometimes however, processes, or programs can go wrong and take up more resources than they should.  If your Computer has suddenly gone on a go slow, we can show you how to check to see what’s going on.

Pressing Ctrl+Shift+Esc at the same time brings up the task manager.  A handy window that shows us what percentage of resources each running process on your computer is using.  This information can be used to identify if something is taking too much and needs attention.  It’s a useful tool to help identify the cause of sudden slowdowns.

The above picture shows the current running tasks, how much RAM, CPU and Hard drive they are using and what type of process they are.  This PC is running smoothly.  It’s using less than half its RAM and the processor and hard drive are all but idle. 

If your PC is going slow this window should be highlighting where the slowdown is occurring.  For example if the column that says CPU is near or at 100% all the time then we call the Problem Processor bound.  Your PC is giving its full attention to something.  This should only be happening in short bursts so if it’s constant then something is hogging the processer.  You can now click on the header for the CPU column to organise the list of running process in order of usage.  It will then group the culprit or culprits at the top (or bottom) of the column and you can begin the procedure of diagnosing the fault.  This process is the same if its Hard drive and RAM column is near or at capacity.

In some cases, the fault lies within Windows own processes and resolving the fault, short of wiping your PC this requires more expertise.  This type of fault forms most of the optimisation jobs we perform in our Computer repair shop in Penrith. 


Other causes of PC slowdown.

Hard Drive Failure.

Although slowly being replaced by faster solid state technology, most hard drives are still mechanical spinning disks with magnetised arms whizzing over the surface.  (picture a record player except the needle floats above the surface and zooms back and forth.)  Like anything mechanical it has a working life and will eventually wear out or fail.  It can be accelerated in laptops due to impact damage but it will eventually happen.  Slowdowns in hard drives happen if the surface of the disk becomes damaged or corrupt and the drive attempts to read data from the damaged area.  This requires a new Drive and can be a great opportunity to upgrade to a larger drive or a faster SSD.


Laptops can overheat when the vents become clogged with normal use.  Overheating computers apart from degrading the solder cause the Software to run slowly and can crash.  Some laptops have an easily accessed hatch to get at the blockage, others require the laptop to be completely dismantled.  This is a very common repair in our Penrith computer repair shop.  We also recommend replacing the thermal compound which we do as standard.

Actual Lack of Resources

Older PC’s and “bargain” new laptops can simply be slow because they are slow.  Older computers might need a RAM upgrade or a faster Processor.  New entry level laptops are increasingly made with soldered on processors and ram and can’t be upgradedmaking for a slow pc.  We think these represent poor value for money.   We have excellent professionally refurbished ex business machines in this price bracket that are significantly more powerful and come with the same warranty and excellent local aftercare.

Don’t forget we offer a free diagnostic if your PC is going slow we can have you up and running in no time.
