So yesterday I did some Fall cleaning on my pc. Just the basic dust it out and re cable manage. When I went to turn it back on, nothing happened. I did the basic, check the cables make sure everything is plugged in blah blah blah...... Nothing was working and after digging through many forums and answer pages I came across and page showing how to reset your BIOS/CMOS. After I did this and plugged everything back in, my PC was alive. Can anyone please explain why I needed to reset my BIOS and what I did that caused something like to happen. Was this my fault or just the PC being stupid?
