I have been searching for this problem but i couldn't find any good answer. Other than "if you are under warranty, take it back" I have the Aspire M5641 and my computer freezes randomly, I have no warranty because the papers got lost (stupid me). I do think it's got to do with the hardware but i allready changed the videocard swapped the memory but stil no luck. Now i think it has something to do with the HDD 2 x 640Gig. Is that possible, and if so does anyone knows a solution for this ? thanks in advance
