Its about 2 years old, bought brand new. Yesterday, it started having what looked like RRoD (red ring of death). But, when I tried turning it on about 2 hrs later, I was able to play just fine. Turned it off and back on a few mins later, RRoD again. It works about half the time, whats happening? I have it on a hard surface, so I dont think its overheating.
