I didn't do anything to it differently, I was just using it last week playing a game and it shut itself off. When you turn it on now, the orange light comes on, and the fan comes on, but nothing at all starts up. When it shut off, I didn't get a blue screen, no error at all, no warning, it just shut off and wouldn't turn back on properly.
Any idea what's wrong with it and what might need replacing?
We looked at it, and nothing looked burnt on the inside, and my husband is pretty mechanically minded and can change parts (has changed several major parts in the computer a year ago), but we don't know what to even start with.
Thanks for any ideas!
