Hello,
Recently I've come across a very puzzling issue, and frankly, I'm at a loss. Three days ago I took apart my computer and cleaned it thoroughly. I used it all day for the rest of the day, but the following day, it wouldn't start. Nothing. No signs of life at all. I've tried everything I could think of; tested the PSU, checked all the plugs, made sure everything everything on the mobo was plugged in correctly, yet it still wouldn't turn on. Checked everything about 4 times... I haven't done any really recent updates to the computer, and it's only about 3-4 years old. Really need some help on this...
Just to clarify, yes I have the power supply correctly adjusted and I have checked; everything is plugged in and I have tried different sockets.
Also, I recently took my motherboard off of the standoffs and mounted directly on the case. This allowed the graphics card and other hardware to fit properly.
