Crap, I came home yesterday and found my PC shut down. I tried to start it up but it refused. This sometimes happens when the power goes out in the house and back up again and until now, the solution had been to take off the power for a while (until the MB is uncharged) and put in back again.
This time however it wouldn’t boot at all. I would boot, the fans made a small jerk like starting the get power and then stopped. Another boot didn’t do anything until I removed power again. I tried a few things, mainly taking out all power except to the MB but it didn’t help either. I am afraid this might be an unrecoverable MB short-circuit and I’m seriously lacking the funds to have an upgrade at this point.
Now the error is either with the MB, the power supply or most unlikely, the CPU. All I can do at this point is change the power with one I’ll take from my job temporarily.
