Question about computers

Like MrSmith said, it definitely wouldn't cause software issues, though it could cause hardware issues that appear to be software related. Unlike MrSmith said, I think poor quality electricity can "jump" the power adapter/supply and damage other components, especially if the adapter/supply is itself of low quality. But yeah, the power adapter for a laptop or power supply unit in a desktop would likely be the first part to go.

And I wouldn't be too worried about the voltage being too high, because if it were there would probably be trouble with more than just computers. Voltage that is too low would be more of a concern, because some devices have to draw more current to satisfy their power requirements, and more current generates more heat. Even so, a steady supply of somewhat low voltage probably wouldn't be too much of a problem, either. If the voltage isn't steady, that could possibly shorten the life of a lot of electronics as they go through more thermal cycles.








Or I could just be talking out of my arse.

I'm not trying to flame you but to be perfectly honest it is more likely that the problem is the users.

That said, as others have pointed out a good power supply will prevent lots of problems but not all of them. An uninterruptible power supply (UPS) might not be a bad investment if you have a desktop. For a laptop you don't need one since you have a battery already.
