And for yet another question, is it always in the same time frame of 8-10 or does it sometimes make it to fifteen / sometimes only get to five. In other words is that period variable or does it stay pretty constant. Second, i concur that it is a heat problem, is there any way that you can try it outside in the cold / or open up the case and turn it on with it disassembled to see if that helps dissipate the heat?
