My PC was overdue for a cleaning so I completely cleaned it last night. However, I now regret it because it won't start. Would like to mention that I've cleaned my PC numerous times before and sometimes I would forget to replug something, but it's not the case this time. Since the problem started Ive completely rebuilt the PC a couple of time to no avail.
more info on the problem. The computer is receiving power: the power supply turns on, the motherboard's lights are on, the fans and so is the video card. But no boot screen or any connection to the monitors. none of the input devices turn on: the mouse, keyboard and all that stuff are not turning on and I've noticed that the light from my sound card is also out. Interestingly enough I've also noticed that there is one particular system fan plug that just stops working 5 secs after i boot (np matter which fan i plug in. This just happens for this one, the other fans are receiving power. I really just don't know what to do anymore or what the root of the problem is, given that everything is plugged in please help. Thank you for your time
