Hello everyone I know you probably get a motherboard question every week, so here is another one. I was working on my pc today and all of a sudden it just shut off. No warning signs nothing. I was simply using the net and it went out. I noticed kind of a burned smell to the pc, so I'm thinking something over heated and it simply shut off. Well I let it cool for some hours and it still wouldn't come back on. I finally got it to come on, but there is no activity to the mouse, keyboard, or monitor. The power supply unit comes on and so does the fan for the processor (AMD Athalon), but there is no other activity. There are no visible signs that anything has been burned. What could possibly be the problem? Thanks in advance for your help.
