When your PC goes wrong and you have lost all hope the normal final stage is to reformat your computer and start afresh. This will most likely resolve any software issues, remove viruses or any other nasties and give you a clean start. But what happens if you have already reformatted and the problem still exists?
This means, most likely, you have a hardware fault. This is where problems can start.
Diagnosing a computer hardware fault can be a right pain as any of the computer components could the cause. Unless you are intending to replace the entire machine you need to carefully diagnose with what components the fault lies with.
I would advise you look at the computer into these main areas to analyse.
Memory / RAM
Power Supply
Hard Disk
Motherboard
This isn’t a complete definitive list, obviously depending on your issue ie if your issue is that you don’t get sound then it could be a sound card issue, similarly if you don’t get a display then graphics could be the culprit. If it is a random fault then either of the above could be the cause.
