So today, I was playing GTA, nothing my computer can't handle, when suddenly, the screen froze and alt+tab/ctrl+alt+del didnt work. I shut down my computer, and when i tried to turn it on, 5 mins later, the power button flashed orange, and it started beeping. I unplugged everything, took off the side panel, and looked around. Nothing was out of the ordinary, so i closed it up, plugged it in, and turned it on. It did the same thing. I think the motherboard overheated, and the computer is going into a safe mode so that nothing fries. I am running a low-powered fan, and directing it into the case, also turning on the big fan in my room. If you can help, please just let me know. Thanks.
