So today I got all hyped up ready to play some Fallout 3. Turned on my 360, and was kicked in the groin by a completely random rrod. I had used my 360 the night before for all of 20 minutes to play a little silent hill, and when I turned it on today, boom. This is the third RRoD thats happened to me, first was back near launch, then again a few months after getting my repaired system back. Since then it had all been working good, and I guess I was too content with my little system having just installed the 120gb hard drive. So since I've obviously modded my 360, I can't very well send it back in for repair. I've been researching all the possible ways to fix the problem, and I'm leaning towards the x-clamp fix. Any suggestions or thoughts on how I should proceed?
