I just got this Dell 990 i5 and it keeps making this noise like there is a flash drive in there but there isn't. It is that dropping off noise. I added this SSD drive installing Windows 7 pro and wondered if that is doing it. I hate to reinstall the regular hard drive that came with it but I am afraid I might have to. Oddly, when I added a new higher watt power supply, the drop off became worse, even to the point of completely shutting down. The 600 watt power supply tests ok but I removed it and the drop off noise decreased with original power supply but it still happens every now and then. I hate this when it is hard to diagnose the problem. Actually, I just got a new power supply and it is doing the same with with dropping off . The only thing, hardware wise, is this SSD drive I disconnected the Blu-ray DVD player. But with the new power supply it shuts down.
