^ when i buy parts, specially monitors, i kinda got it to habit of bombarding it with stress tests for at least 3hours straight, if not a single error pops up i can either decide to let it stay asleep for a few weeks or go and use it.
PS: for monitors i use 5different colors(black, white, red, blue, green) and random shuffle it, slow at first to see if theres any dead pixel, and then increase the rate to 60FPS to match the refresh rate of the monitor.
