Recently when I was playing sniper ghost warrior 2 I got red ring of death in my Xbox 360.3 red lights starts flashing in the quadrant, fans stops working when this happens and I noticed that my power supply light has turned orange. I took my Xbox apart as my warranty period have finished. I changed the thermal paste and cleaned the dust, installed everything back correctly. When I turned it back on still nothing happened. Then I took apart my power supply and noticed that the small fan inside is not working. i installed a new cpu cooling fan and that should take care of the power supply for sure.my console switched back on but after 2 hours of gameplay the error comes again. Where could the problem be.is it in the power supply or the console. I have also noticed a few days before this happened the graphics were also a bit lower than before and after red ring of death it still remained.
