I recently purchased a new hard drive and installed Windows 7 onto it because the old one failed, but the problem started before I did that. I have other USB devices which work fine such as printer and scanner. I just tried connecting my microSD card with a new adapter and it worked OK as did a USB flash drive, so I think maybe my old adapter was faulty. My USB drivers were fully up to date.
I removed the battery for 10 minutes and restarted, but it didn't help with the problem.

You might try checking your voltages using something like HWmonitor to verify the 3.3v, 5v, and 12v, are all within spec (5% of 3.3, 5, 12).
Any single usb device that has a problem, might interfere with others. A bad usb port with damaged or bent pins might also cause an issue. Visually inspect all usb ports on the MB, Case, etc for damage or shorting pins. Flash drives and microSD cards do not need as much wattage to run when compared to external hard drives.

Here's the HWMonitor data:

Those all look ok, that didn't show the min, avg, and max. Can you let HWmonitor run for a while and then take a screen shot? What you will want to check is that your min and max never go out of spec.

My USB drivers are up to date. I'll try to get hold of another PSU. Here are the results from HWMonitor after 12 hours:

All of the voltages are within 5%. While that doesn't mean for certain it isn't still psu related, it would seem unlikely at the moment, it would still be worth trying a different psu if you have one available.
Have you tried removing the USB 3.0 PCI-E Card and then just using onboard?
