In this post I describe how I deal with all sorts of hardware failures and how I identify faulty components. Perhaps manufacturer tests are incomplete, or the parts get too often damaged during transit, who is to blame? These parts, which normally passed manufacturer tests and quality control checks, will still give you an ocean of random crashes and a few headaches. The truth is, depending on the manufacturers and type of hardware, an average of 20 to 25% -one every four to five- of computer parts actually exhibit a hardware fault of some sort, which is not always obvious at first. This uncertainty will often make it difficult to get parts replaced or refunded by retailers, who will happily charge you a fee to return your goods back to you when they find that they work correctly. It is not always possible to determine exactly what parts are wrong, and the process of determining what is wrong in a system almost always involves some form of guesswork. I have been dealing with tons of hardware failures in the past, including ‘esoteric’ failures that would randomly occur once every month, or things that you would never guess such as this brand-new and reinforced SATA cable that works flawlessly with some HDDs but not others, or even a bad USB hub or mouse. This is because most faulty parts will not be fully dead, instead they will appear to work well for some time and then fail, either randomly or with increased system load and temperature. Many things can go wrong when testing a new system, and it can be quite difficult to find out which components do not work well.
Surely this is a software error, or is it? What the heck? Retailers say that less than 2% of computer parts are faulty. Or perhaps you got a BSOD or a kernel panic.
Everything looks smooth and fast, you hear the fans spinning up and a little coil whine when the machine does something that is obviously important, and you think that it may actually be alive with a temper of its own (which may or may not be a good thing). You just put together your $(insert a three- to five-figure amount) new rig, booted into your preferred operating system and installed your tools and games.
They can also occur during gaming and heavy CPU/GPU compute, which makes troubleshooting slightly easier.Īnswer: The PSU (850W) was underrated and an ECC RAM stick was faulty. Random freezes, reboots and shutdowns are the hallmarks of hardware failures, and most of the time they will occur randomly when they are the least expected, e.g. Troubleshooting hardware-related issues is not as straightforward as it seems. Hint: Two components were bad and causing similar symptoms. This high-end dual-GPU setup was rebooting randomly, can you guess why?
