My computer has been randomly shutting off lately. When it does the fan in the back gets very loud, I'm not sure if it's my PSU or GPU. After that my computer won't turn back on, it just cycle restarts. I let it sit for a couple hours and it turned back on. After being on it for about 2 hours it got really loud again and then shut off. I don't know what the problem is. Does this sound like a power supply problem? I have reset my CMOS and I have made sure everything is plugged in. Any help? I also had motherboard error 04.
