Checkout our pc booster to make your pc run faster
If your computer is running slow there’s no reason why you can’t improve it’s performance significantly.
Especially if it’s never been cleaned up or tuned there are a number of ways to do this, but they fall into two categories hardware and software ,
Here we are going to talk about how to improve the performance via the hardware side of things
After you’ve read this why not read our cleaning hard drive and computer speed up articles to improve the software performance side of things.
Hardware performance is all about bottlenecks, your pc is only as fast as it’s biggest bottleneck or slowest component so the list of possible bottlenecks are as follows
- Processor
- Hard Drive
- Ram
- Graphics card

Depending on how your finding your computer to be slow has a big baring on which components you need to replace,
The first thing would be to clean up the disk or try to software tune the operating system, we have guides on both of these subjects.
Once your satisfied that you’ve squeezed as much performance out of the pc as possible , now we can start looking at hardware upgrades.
The ProcessorIf your system is slow when running calculations this would indicate the processor is struggling,
you can check this by hitting control alt and delete at the same time, select task manager and then select the performance tab, the top graph here, CPU Usage history tell us how hard the processor working,
if the line is at the very top then the processor need to be looked at or replaced, “note” if you decide to replace the processor make sure that your current motherboard can support a faster type.
Most motherboard have limits on the kind or speed of the processor they can handle.
The hard drive can make a big performance difference in a positive or negative sense, if applications are taking a long time to load or files are taking a long time to copy over then it would be worth upgrading the Hard Drive,
There are 4 kinds of Hard Drive on the market, SCSI, IDE, SATA and Solid State, we’re not too bothered about SCSI here as this type in mostly in servers, the ones that we are interested in are SATA and IDE , SATA is the fastest of the two it has a transfer rate of 150mbps. (Solid state drives are the quickest around, but are much more expensive)
IDE drives, this is probably the type you have in your pc at the moment, range in speeds from 33,66,100,133mbps, if you going to upgrade I’d recommend either going the SATA route or the IDE with a 133mbps type drive, depending on your motherboard though,
you will probably have to purchase an extra controller card to take full advantage of the speed of your new drive, but it’s definitely worth it If you need help installing or fitting the new drive read our articles on this install hard drive format hard drive The Ram
Generally the more ram a computer has the better, please bare in mind some motherboards do have limits on the amount that they can handle,
Running Windows XP , 2000, Vista or 7 3gb will make a big difference to the speed.
Graphics cards Today 99% of the the most complex programs are games, when you consider the amount of graphics power required to run the latest games its staggering,
if your card has under 128mb these days and you like to play games, change it, your really need 128mb minimum these days,
once again though check your motherboard to see if it can handle the latest x8 AGP cards.
pc booster One thing overlooked today is the cooling, if your computer seems to run faster when it’s first switched on and then begins to slow down, throughout the day,

I’d look into the processor cooling, maybe increase the size of the heatsink and make sure the processor fan is working ok.
When a processor does get hot or overheat it will slow down.

You can also check for any hardware issues, usually by running the computers built in diagnostics, for Dell computers you just select the F12 key as the computer starts up and then select diagnostics and let it do its thing, works very well.
