I bought a emachine two years ago. Mother board fried. Luckily it was under guarantee and was replaced free of charge. Here we are two years later and all of a sudden i keep gettin a message(shut down due to cpu overheating). I bring the computer back to future shop where i bought it. They tell me once again mother board is finished. Guess what? guarantee is finished. So there goes at least a thousand bucks. My arguement is that they had changed this part already once. Shouldn't the guarantee be from the day they changed my mother board? for all i know, they could of replaced this with a used part or faulty part. Now i'm getting told by friends to just scrap the emachine and buy something new and better. Any advice out there on this problem?
