NOOOOOOO! No baking, like you said this is acidmods not barbies kitchen...lol Kicks mentioned it being a scalar issue, and I have seen the same thing amongst a plethura of other issues. If you do the x clamp replacements, you must change your paste. If you are handy with a soldering iron, I would first try to rework the ANA or HANA chip that kicks suggested.
I wouldn't mess with x-clamp replacement until you have tried every thing else you can(I won't hurt, as long as you are careful and use proper technique) Since it isn't RROD yet I wouldn't overheat anything as of now until you try the rework.
To rework ANA chip you can use a hot air gun(just hit the leads of the chip till the solder yellows a bit), or just wet all pins with a ton of solder so they all bridge then use a solder wick or a solder sucker to remove the the excess so it isn't bridged any more.
