Ok. I've got a weird problem, and I'm not sure quite what could be causing it, or how to fix it. My computer runs perfectly while it's powered on, I have no problems there. It's when my computer gets turned off. Whether it be from myself turning it off, or the power going out, anything that stops the computer from running, I have a problem turning it back on. I hit the power button, and NOTHING happens. I have tried hitting it (the power button) multiple times, but to no avail. I have opened my computer countless times to check if anything has wiggled loose or whathave you, but nothing seems out of place or loose or anything. The ONLY way I can get my computer to turn on, is flip the master power switch in the back, unplug it from the wall, and leave it for 30+ minutes. When I come back, I plug the power cord back in, flip the master power switch ON, and hit the power button, and everything boots up fine, as if nothing ever happened!! I could really use your guys help, this has been bugging me for quite a while now. Thanks in advance for any help you can provide.
