I've had this computer for a long time and i've been playing games, watching youtube, etc. But now after such long time after not downloading anything for a few days, i come back to my computer from school and i play on it. But after an hour maybe.. it turns off but with a very slowly starting with the screen turning off. It does not shut down or restart it just slowly turns off.. even during a game. All the lights go off on it i dont press any buttons to make this happen but when i press the power button everything goes back on. it shows the startup screen before going to my desktop showing everything is still on and going. I looked on the internet as much as i can to find out what's wrong but i end up lost, confused and/or just having no solution.
