Hello, I have a shuttle machine (SN45G) and recently I have tried fitting a Titan Copper cooler to my noisy 9800 Pro. I did it after around 2 hours of trying and then when I booted up the PC, it seems that the my primary Master has changed round with my slave and so the PC is running ridiculously slowly. I think this belongs in here and not in SFF PCs as it isn't shuttle specific. Please, please can you help me and tell me what to do, many thanks, Alex
