I opened my PC to find out manufacturer, model and version of my motherboard because I unfortunately don't get the code at the lower left hand of my screen during start up (the warranty is up anyway). Anyway, the problem I'm having now is starting up. When I hit the start button, it starts and stop every 1 or 2 seconds. The only bad thing that was done when I opened it was my brother touched a chip with a piece of metal. Could that be the cause of start up failure? Thanks for any input.
