Help!!! I have built dozens of systems over the years but this has never happenned to me.... I bought all these parts to build a system for a customer... Biostar Motherboard M7VIF AMD ATHLON XP 2000+ CPU 512 MB DDRAM ATI RADEON VIDEO CARD ONBOARD SOUND INTEL MODEM 80 GIG MAXTOR HDD CD BURNER I put together the system yesterday. As soon as I plugged the CPU onto the motherboard and installed the cooling fan and memory and video card, I powered it up and smoke started to come from somewhere around the CPU and it smelled really bad. It was running for no more than 15-20 seconds max! I took the CPU out and visually inspected it. It looked fried on one corner of the little chip on top of the unit, and smelled burnt. I tried the chip in my existing PC with an ASUS A7V133 MoBo and it wouldnt even turn on. I didnt know if the chip was defective or another part caused it to fry, so I tried the RAM and Power Supply in other systems and they worked fine. Then I put another CPU I had, on the new motherboard and it worked fine too. So I concluded it was the new CPU itself that was just defective and nothing else caused it. I went back to the store where I bought the chip and they have a "NO RETURN OR EXCHANGE POLICY" ON BURNT CPU's. I insisted that I am experienced in building PC's and it must have been the chip that was defective, but they didnt care and told me to call AMD to see if they would take it back. They werent even willing to test it. I buy all my stuff from this store but they didnt care. So I told them I would no longer buy anything else from them because their policy was unfair. I went somewhere else and bought the SAME CPU (AMD ATHLON 2000+). I went home and plugged it into the MoBo and it worked just fine. I made no changes to any settings on the board. Everything was at factory default. I have had it running for more than 24 hrs straight with no problems. My question is....has anyone had a similar problem and how do I go about contacting AMD and making my case to them. I want them to replace it or at least test it to see what went wrong and if it can be fixed (ha ha). Otherwise I have to eat it and I am out $210. Any suggestions??
