I tried to heat my freerunner, since I get the WSoD in normal temp, but I
can't get ride of it. I get the WSoD after ~ 5min (always).

I get a quick WS(oD) when I am booting up my freerunner. It flashes and the
continues like normal. 

Question to the temp-guys (great work by the way):
What happens if you take the "frozen" FR that displays WSoD, backinto resume
and "heat" it for a while, can you resume normal then?
