Random Blue Screens and Computer Crashes

Akin to the above subject, a power supply spoiling can lead to a blue screen, or a “tough” computer system freeze. Unfortunately, crashes are among the broader areas of computer system problems. A lot of hardware and software drivers can cause a blue screen, and a few of them can cause tough freezes too. If you’re getting computer crashes, don’t suspect the power supply immediately, however keep it in mind as you test to see what’s going wrong.

Power Supply Fans Make a “Grinding” Sound

Ensure you acquire a well-reviewed and trusted tester if you go this path. Incorrect or complicated testers will just make things even worse!

If you seem like a bit of an electrical expert, you can test the outputs yourself using a multimeter to get readings from the power supply’s output. Nevertheless, this takes advanced understanding of how a power supply works, in addition to how to get the readings. Just use a multimeter if you’re positive in your capabilities to use it properly!

Change the Power Supply

If you can validate the power supply is going bad (such as a loud fan within it), then getting a replacement is ideal. Note the quantity of wattage your old power supply is (generally on its requirements sticker), then buy a new one with the same or higher quantity.

Look For Professional Aid
