Computers are known for their fragile components. It's not uncommon for them to break for no apparent reason, though deep within the case, there will be a valid reason as to why it did. Finding that reason out is the focus of all computer repair. Once you find it, you can determine whether it's possible to rectify the problem or replace it.
Power supply units (PSUs) are an unsuspecting component within computers. They aren't usually considered to be the most fragile within the case, yet they do have a habit of breaking more often than anything else. This is especially true in custom-built ones.
For example, if a desktop PC draws 400 watts worth of electricity, yet the PSU provides only 400 watts at its peak, then it will be under maximum capacity at all times. This means it will be running at its hottest 100% of the time, which isn't good for the components. Contrast this to a stronger PSU, which might only be operating at half the capacity, and hence, a much lower temperature.
Additionally, this peak pressure will increase the temperature within the PSU case. For every few degrees it goes up, the wattage decreases, meaning its peak becomes much lower. It's a vicious cycle and can cause serious issues, such as damage to the PSU. Components within it can even melt or begin to burn.
The other components within the PC are much more difficult to repair. If even the smallest part is damaged, it might be easier to replace it, rather than fix it. Trial and error will tell you which components are damaged.
Computer repair involves taking each component out, then using the inbuilt one or a working replacement. This allows one to discover the weak link in the system. Sometimes, it might simply be easier to introduce a professional into the mix to properly identify the weaknesses and provide advice on how to proceed. Doing it this way also preserves any guarantees you may have from when you purchased the machine.
