Ok I have a computer runnign Windows 7. The motherboard is A8N-SLI Deluxe which is quite an old motherboard.
I am having problems with USB2.0 transfers. My USB ports are showing as USB 2 but the speeds I get fluctuate from 3m/s to 40m/s (mainly 3/ms). I was wondering if it is Windows 7 causing the problem as the motherboard is so old. Should I downgrade to XP ??
