First make sure that the USB device is plugged into the correct USB port. Old computers will have USB 1.1 ports, which might not function right with all modern USB devices. If using a USB hub, try plugging the device into your PC directly rather than via the hub. Some USB devices need to draw power from the port to function and a hub may not provide enough orany power. If these solutions still don't resolve the issue, the problem is likely related to the USB device's drivers. Go to the device manufacturer's website and download any drivers that the company has made available, then reboot your computer and try your device again.

If you are running Windows XP, this problem is likely caused by a specific program that is consuming more memory than it should. Go to the Processes tab of Windows Task Manager and sort the active processes by Memory (Private Working Set). Terminate any program that's hogging memory (bear in mind that you might lose any unsaved work). If this problem happens consistently, consider uninstalling the software causing the problem. Windows Vista and 7, however, do not require any action. They are designed to aggressively use system memory in order to reduce the load time of frequently used software. This behavior is normal and advantageous.
Do a Windows Search for msconfig for Windows Vista and 7, or Run the msconfig program if you are using Windows XP. Navigate to the Startup tab and review the programs listed there.
