so i had the RRoD. I opened it up, found a ton of dust, cleaned it off. i kept turning it off and back on, and each time it got a bit louder, until it finally successfully booted. (i was so proud of myself lol) i booted it successfully about 3 or 4 or 5 times, until the next time it got so freaking loud i thought it was gonna blow up. It then got silent and showed me two red rings, (overheat issue). i let it sit for two hours, no change. what should i do?!?
