Hi, this is my first time posting here and today i have been through quite some trouble. After getting batman arkham origins i was thinking of trying it out on my xbox 360 which i haven't used/plugged for months (maybe half of a year). As i plug my power supply into the wall outlet i can see that my power supply makes a orange/red blinking light even though it's still not plugged in the xbox. So i still tried to plug it in my xbox and then my power brick light was more like red blinking and my xbox started to make weird whistling noises. Also my back fans starts running everytime my xbox is plugged along with the noises and of course it won't turn on. The problem is i'm not sure whether it's my xbox or power supply that is broken and needed to be changed.
Thank you for your support and sorry for my bad english.
