hello, My friend has a problem with his pc, it is a 1 year old meadion. The problem is when his pc is booted up, the case light comes on then there is a beep and all of a sudden the pc switches itself off. I have not acctualy had time to check out the problem, but he said last week the pc had a similar type of problem. The pc is generally left on all day and the hard drive was making noticably loud creaking noises which it did not do when it was new. My guess is that it could be either the motherboard, cpu or even hard drive. any suggestions anyone?
