If you're low on memory, adding more can be the the single most beneficial upgrade for many types of use case scenario. When your PC is close to running out of RAM it will start spilling data over onto the hard drive. This in turn causes a great performance hit because hard drives are far slower than system memory. Windows 8 can run on as little as 1GB (32-bit) or 2GB (64-bit) of RAM, but many high-end gaming systems stretch up to 16GB and beyond. 8GB is usually the sweet spot between price and performance.

Some applications on your PC are set to automatically run as soon as you log into Windows. The more applications set to do this the longer your PC will take to start-up, and it uses more RAM as a result. Windows 8 makes it easy to disable apps through the built-in Task Manager. In Windows 7, try CCleaner or Windows's built-in tool that's accessed by typing msconfig.exe into the Start Menu.

A program designed to be a one-stop shop to regularly clear the crud out of your Windows installation, CCleaner is free but has a paid upgrade. It can keep all of your Windows temporary files (among others) at bay by regularly deleting them and acts as a registry cleaner too.

A handy alternative to Windows's built-in defragmentation tool, Defraggler has a friendly user interface and will install an option in your right-click menu so that you can defragment individual files or folders.

For a gaming PC, it means you can concentrate on defragmenting game data to make levels load up faster. Defragmentation provides a modest performance increase, but every little bit helps. Note that you don't need to defrag if you have an SSD, and it could actually harm the drive.

That said, SSD owners should enable support for TRIM, which lets operating systems inform SSDs which data blocks are no longer needed so they can be wiped internally. See our guide on SSD maintenance for more.

Not keen on defragging? Swap your hard disk for an SSD instead. SSDs are now coming down in price and their durability is getting much better to the point of where it is now a practical option for home users to upgrade. The primary benefit of an SSD is that the speed at which data can be read from a drive is far greater than that of a spinning drive. Say goodbye to (long) loading times.

Overclocking, the arcane art of making your CPU and GPU hardware run faster than it was meant to go, is an option available depending on your motherboard and its BIOS options. If you know what you're doing, overclocking can make your old hardware seem brand-new. However, you should proceed with caution as this can irrevocably damage your hardware, invalidate your warranty, and requires serious consideration toward cooling. Intel XTU, a software application that lets you alter your CPU's frequency, voltage and other controls, is used by some of the top overclockers in the world.

If your hard drive begins to develop errors, the performance of your system will suffer as read and write speeds are delayed while the drive tries to compensate. If you regularly run programs like ChkDsk, or even Steve Gibson's SpinRite, your drive's own SMART self-diagnostic hardware will take care of any problems as best it can, and it could even alert you if you need to replace the drive in good time before it dies.

PC Decrapifier is the perfect tool if you've just bought a PC from a manufacturer who loves to fill their products full of bloatware.

As part of tuning up and cleaning your PC, it's a good idea to get rid of any software that you don't need. Not only does this free up hard drive space, it also reduces the likelihood of things you don't need running in the background.

We all know far too well that Windows is not free of bugs. As such, to get the best performance (not to mention the strongest security), it's a good idea to run Windows Update manually, or set it to automatically update so that your OS is always up-to-date. Ensuring Windows is fully up-to-date can plug security and other holes while making sure drivers are updated. To review your Windows update settings type "Windows update" into your Start menu / Start screen.

Part of the online gaming experience is communicating with other players. Sometimes the built-in communication tools of the game aren't that great and you need to turn to third-party solutions. Everybody knows Skype, and most of the time it works well enough. Free users can even do conference calls, which means that Skype could be a solution for in-game communication for PC users, just as it is for Xbox One owners.

Software on your PC is not just limited to applications that you interact with, it also consists of so-called services which enable various features on your PC. However, some of the services that run in Windows are not necessary for everyday use. For example, if you only have one PC in your house you could disable file and printer sharing to free up resources.

Whether you have a graphics card from Nvidia or AMD, you can get the most from your graphics card by installing the official control centre software. In the case of Nvidia this is the Geforce Experience, for AMD you will need its Catalyst Control Centre software.

Additionally, these allow up to update the drivers for your graphics card to optimise a gaming PC. By staying up-to-date with the latest drivers from your graphics card maker you will benefit from all of the optimisations that have been squeezed out by the original manufacturer.

This is something of a no-brainer, but getting a new graphics card with a much more powerful processor will massively improve the gaming performance of your PC. Another option if you don't want to throw away your current card but also have a spare PCI Express x16 slot on your motherboard is to buy a similar card to use in parallel. With Nvidia cards the system is called SLi and for AMD cards it is called Crossfire. You should check online to see how closely your cards need to be matched.

By default, Windows will regularly keep an index of everything on your drive so as to speed up its internal search functionality. This is fairly resource intensive, and the chances are that you rarely use Windows search function. In any version of Windows type "indexing options" into the Start menu. From there you can opt to stop indexing all folders or limit indexing to a particular set of folders or file types.
