It's not reliable fixing yourself, it'll break again, seriously

Yours are exeptional and I will not try the x-clamp after I know what will it cause and what is the root cause of it.

Did you actually know what you're dealing with when you hit 3RRoD and why the x-clamp fix will work?

You can get it work it's your mere luck, I also got some friend that did x-clamp and never fail thereafter but those are very rare and usually the box operate in an airconditioned room.

The best repair is send back to Micrsoft singapore where this is the only reliable fix which will not recur.

All other repair is interim and did not address the root cause of the problem.

and based on your post on another topic, it's very clear that you use common sense to think but never use your brain to think.
