Stress your computer to find out how stable it is.
Stability is what we should look for when building a computer or getting one already put-together. There isn't anything wrong with putting a PC to stress, unless is faulty. Nobody needs a ready-to-crash computer and if there's anything wrong with it, we should find out in the shortest possible time. With this thought in mind, developers have worked with scientists in order to deliver top-notch benchmarking tools based on elaborate mathematical algorithms.
IntelBurnTest is one of those applications. It is based on the Intel Linpack, a very demanding application that stresses the components of the PC to high extents. If you're unsure of the cooling power of your rig, we recommend that you firstly check it out with some temperature reading apps and then go for a test. Until then, you may use this software at your own risk, although you don't have to be an extreme overclocker to push your PC around to see whether it's a winner or not.
