Xbox shuts off after about 20 minutes of gaming
Like the title says, my xbox seems to turn off only when I play games. I had it idling on the home menu for about two hours, but 10 minutes into Forza 5, it shut off by itself. If I attempt turning it back on afterwards it turns itself off again. The only way for it to turn back on is to unplug everything and leave it overnight.
I've opened literally every part of the xbox including the PSU and blew out all the dust I could find. I've tried power cycling and factory resetting and nothing seems to work. The heatsinks never seems to get excessively hot when playing games so I'm not sure if the issue is caused by overheating or not.
