Hardware! Isn't it luverly?!
We build our own PC systems here at Winpenny Media, and while building systems for others, and generally tinkering with hardware, is not something we do on a regular basis, it is something we could offer to do for you if requested. More often than not, however, it will simply be much cheaper just to buy a system from a dedicated system builder, which is what we would normally recommend.
We expect that it is much more likely that you need help with an upgrade or repair. We are quite capable of helping out with any hardware upgrades you may wish to carry out on your system, if you don't feel you have the expertise to do it yourself. If you have never performed an upgrade or repair on your PC before, opening the case up and inserting more memory, a new graphics card or a new processor can be a daunting process.
So, if there is any element of your PC hardware which is causing you concern, please contact us, and we'll see what we can do for you.
(In the near future, we will be sharing nuggets of our knowledge and experiences of PC hardware online. Hopefully, we might be able to offer assistance to other users who could be struggling with the same sort of problems we have tackled in the past).
