I've had this dysfunctional POS on my desk for slightly over 3 months, and at least once per day it requires a hard reboot, regularly to the point of unplugging the machine for a few minutes. Because the power supply is "iffy," the Windows restart function doesn't work. At all, apparently. That makes installing  Windows updates which automatically restart the PC... challenging.The system seizes up three or four times a day, usually when doing the hardest things, like saving a Word file to the desktop or opening Zoom. Today the machine took 8 seconds for the CALCULATOR program to add two numbers together. I beat the bloody computer by several seconds. In ADDING.Later, the hard drive was at 100% usage, and then the memory usage was at 100%, and NO PROGRAMS were running, except for the bare minimum  (i.e., the desktop was visible and the mouse & keyboard still worked.)When I replace this half-brick with something that runs at least as well as a pet rat in a play wheel, I think I'll take it out and smash it with a sledgehammer or giant pipe-wrench while wearing a GoPro. (It being the PC, and not the pet rat. I love pet rats.) Viral fame, here we come.(Review written on a different computer, so I could be sure it wouldn't crash under the strain of having to endure multiple keyboard strokes.)
