Okay so last week i started a download and kept it going for 3 days straight without turning off my computer without any problems. Then for one night I kept it off. I woke up and played games on it for maybe a day or two (again turning off the computer every night). Then my brother and sister a day after played on my computer for a very long time and it started smelling bad, like something burnt or maybe just very hot metal, so I suspected it was an PSU issue and that I would get it fixed soon. The next day my brother and sister played on my computer running a game again for 100 minutes about and nothing had happened outside of the fact that it smelled really burnt, and decided I shouldn't use the computer until it gets fixed. Then the next morning (again turning my computer off overnight) my sister comes and asks if she could play a game, as dead tired as I was, I forgot about the issue I had been facing for the past few days. I let her play and after an hour or two the computer shuts down without warning. It did not work to turn it back on, absolutely nothing works when i try to put it on, not the fan in the PSU or the CPU fans, LED lights whatever. Then I did more researching and I wondered if this also could be a Motherboard issue? To be honest I don't know what a motherboard is or where it is located, but when I do try to turn on my computer I see a little light occur on that big chip (don´t know whether this big chip is the cpu or the motherboard or whatever) that everything else is stacked on in the computer (everything else meaning the CPU fan, video card, sound card). And this light only ever shines at the top of the chip, closer to where the PSU is and kind of close to this golden thing that says GIGABYTE on it. If you guys need me to put up pictures or something to see the inside I can put them up. Thanks for any help that you give me!
