My Win 7 Professional on my i7 desktop has started to be VERY slow indeed. Hangs when you try and do something for several seconds, and then continues etc. + occassional blue screen.
I tried reinstalling over the top, but that didn't help anything.
I ran HD Speed, and was shocked to discover my ST31500341AS 7200 1.5TB SATA 3 GB/s drive is giving me readings of only 3 - 4 Mbps. It will oscillate up and down, too.
I ran HD Tune against it, and got the info below...
Is this likely to be the HD going bad, or a windows issue? Would a clean reinstall likely help. Does PIO come into this? how can I check that? I have a Intel 6 Series/c200 series Chipset Family 6 port SATA AHCI Controller.
