Hello last week i purchased a new motherboard. It was the pcchips m848alu. When it arrived i built it up and switched it on. When i did this the processor fan chugged and a burning smell filled the room. I quickly disconnected the power and inspected the motherboard. I then noticed the primary IDE port was badly scorched. I had read some bad reviews on this board so i decided to return it to ebuyer, the shop where i bought the board from. Within 6 days they had processeed my return and said the board was faulty and sent me a replacement under no extra charge. Today i got my new board and built it once again, taking more care to make sure i did it correctly. When i switched it on it did the exact same thing as before.........burnt the primary IDE port. Now i dont believe the board is to blame and i am wonrdering if the power supply is faulty. When i built the machine the only hardware i connected was the processor and fan, the power supply, the video card and the harddrive with the operating system loaded. Now from these points what do you think is causing this problem. Hardware: XP 2000+ geforce4 4600 Maxtor 40gb Encer 500w power supply. Thanks for your time.
