Helping people with computers... one answer at a time.

Perhaps the single most under-appreciated component in your computer the power supply is not only responsible for providing the proper power to bring it all to life, but is also the source of various and perhaps not-so-obvious classes of failures.

Could my power supply be causing memory errors?

Computer power supplies can fail, and not always in sudden and obvious ways. Failures can be gradual, and can manifest in many different ways.

Do I need to protect my computer from lightning?

Problems with the power to your computer can translate into damage to your computer and data. I'll cover how much protection you might need.

If shutting down Windows cleanly is important, what happens when the power just goes out?

We're all told to to shut down Windows before turning power off, but what if the power just goes out? If you'r not protected, bad things can happen.

My computer is crashing and having troubles, is it time to replace the power supply?

Computer crashes and other difficulties can certainly be caused by a failing or overtaxed power supply, but there are other places to look first.
