Just to keep this simple. I built a pc with an AMD 1800xp processor. It worked fine for a couple of months. I then gave it to a friend who was very pleased with it. He then came to work one day and told me that there was no video output to the monitor. As I had a video card exactly the same spare, I place this into the AGP. Now, the computer booted up and showed XP loading, there was a high pitched ping and the monitor then said 'no input' I have tried both cards on an other system and they have both failed, therefore the cards must be getting damaged somehow. When I built it I was confident that all my BIOS settings were correct, frequeny multiplier etc. However, my friend claims that he was dowloading music from a p2p source and thats when the first card blew (it was fine for 2 months previous) The second card blew as soon as XP was starting for the first time !! He also mentioned a power cut. I cant understand this and ive not got the time nowadays to sink my teeth into this one. Can some great person pleeeeeze help me. Thanks.
