I think i just bid for it XD starting price was around ~50$
hoping reapplying thermal paste will solve it.
Is your prospective vendor an l_mayhew2009 (or somesuch)? If so, that's the one. If you win it at a bargain basement price, and manage to get it working for a few bucks more, let me know so I can
kill you and everyone you've ever loved with my thought rays
congratulate you on your resourcefulness and enquire politely how you fixed it.
ETA: oh in our communications, the guy did reassure me that the white goo was thermal paste... which, considering how prominent it was, might easily be the cause of the problem for reasons D+T explained. OTOH he might have removed and reapplied it himself by now.
