I noticed my system started dragging all of a sudden. This happened after I blew the dust out and installed an ATI 4870. I launched HD sentinal and saw the performance level at 50%. I rebooted and checked bios settings. Nothing seemed out of place. My other drive was still looking good. Got back into windows... and it was 100% performance. So i start to do a defrag and I watched it. About 5 min later it drops to 50% again and the system starts to drag. I rebooted it and back at 100% again. It seems to do this when the temp hits 45C.. I have a good size fan on it right now and its only going up to 43C.. I would think it would be cooler but guess not. Ive tried reseated my cables with no luck and even moved the drive over to the port that the other drive is showing good on. Same problem. I was defragging with a huge fan just now... everything seemed fine. I launched aim and saw performance drop to 50% again... WTF?
