Power won't stay on flashing

what system is this? My gamecube had a problem. Turning out to be a wacky solution, was our plug in controller making the system act up! We had some that were wireless and we could ust the system no prblem with those, but the normal wired one would only flash lights and then turn off completely. Try unplugging all cords, and plugging back in after a few minutes. For some reason this fixes problems. If it doe not work for you, try the manual if you still have it. All manuals for video game systems should be available on the company's website as well as their customer service contact phone numbers to talk to tech support. I hope one of these options works for you! :)
