My PC mouse freezes when loading Photoshop... for about 3 seconds, very annoying can you help? MY windows media player is slow to load my large playlist is that supposed to happen with SSD's?
Try a couple of different USB ports, and update the motherboard USB drivers. There's typically a couple of different USB controllers on a motherboard with many USB ports.
