Windows 7: USB not recognising drives

USB not recognising drives

When I connect a USB SATA drive to win7 pro 32bit it cant see it. Power is getting to the devices since the light comes on.

Changed to another port to no avail.
It and another drive work on a laptop nearby.

An Epson printer is USB enabled as well. Changed the port and that's recognised.
Can you advice please.

As a test:
Disconnect the printer.
Connect the external USB drive to the port used by the printer.

Does the drive work now?

No, no change. Can't see the drive.
Also changed the printer to the ports I tried for the drive and the printer has no trouble in any port.

64 bit Windows only recognising 4GB of RAM.
Hi All I am guessing this is going to be a stupid question, so I do apologise in advance. I have installed a full version of Home Prem 64 bit, but it only seems to want to detect 4GB of RAM. I only have 5GB installed at the moment, so it is not a great deal, but it is still confusing me. ...
