Desktop Boot Loader Failure
In July, on a whim, with nothing better to do over the weekend, I decided to clean out the dust from my desktop PC – it hadn’t been cleaned in four or five years, and there was definitely quite a lot of dust accumulated. After cleaning it, I restarted the system, and everything worked perfectly fine. The computer wasn’t turned off regularly; it was left running constantly, with just the monitor switched off. Luckily, my wife came to stay, and she noticed various light sources at night, so she casually turned the computer off.
