How to identify common PC issues

Jonny

As the title suggests, I'm a little bit interested in learning how to identify common PC issues by looking at the symptoms, is this possible? and if so how do I identify the malfunctioning component? any help would be appreciated thanks.

It is possible to identify based on symptoms. Here are some common components that can fail and the problems their failures may cause:

Hard Drive: If your hard drive starts failing, files on your hard drive may become corrupted. You may see long delays when you attempt to access files or save to the hard drive. Windows may stop booting entirely.
CPU: A failing CPU may result in your computer not booting at all. If the CPU is overheating, your computer may blue-screen when it’s under load — for example, when you’re playing a demanding game or encoding video.
RAM: Applications write data to your RAM and use it for short-term storage. If your RAM starts failing, an application may write data to part of the RAM, then later read it back and get an incorrect value. This can result in application crashes, blue screens, and file corruption.
Graphics Card: Graphics card problems may result in graphical errors while rendering 3D content or even just while displaying your desktop. If the graphics card is overheating, it may crash your graphics driver or cause your computer to freeze while under load — for example, when playing demanding 3D games.
Fans: If any of the fans fail in your computer, components may overheat and you may see the above CPU or graphics card problems. Your computer may also shut itself down abruptly so it doesn’t overheat any further and damage itself.
Motherboard: Motherboard problems can be extremely tough to diagnose. You may see occasional blue screens or similar problems.
Power Supply: A malfunctioning power supply is also tough to diagnose — it may deliver too much power to a component, damaging it and causing it to malfunction. If the power supply dies completely, your computer won’t power on and nothing will happen when you press the power button.

I was looking for this information too, thanks Josef

Blue screen under load could also be an issue with the power supply.
