Remove both Ram from the laptop and test with Each Separately.

Usually this means the computer saw that something was plugged into the USB port, but it doesn't know what device it is. It will require device drivers from NEC to recognize the drive. If your drive came with a driver CD, install these drivers. If the drive was working before, but now it's not, reinstall the drivers. If this does not fix the problem, then most likely either your drive is bad, or else your registry has become corrupted. Try another USB drive and see if your USB port is working, that is another possibility.

Hello, I suggest that you check the connection of the motherboard and your computer's screen because it has something to do with it. Or if resetting the connection won't do anything then I suggest that you let a tech check it. David

Drivers are very difficult to come by for that sound device. Do you have any more detailed information.

You should open your computer and reset the data cable which connects the motherboard and the screen. If it's not going to fix it, then you would need to get a technician to look at the motherboard and the LCD so that he can identify which part is causing the problem. David

Disconnect the power cord and battery. Hold down the power button for a minute and then connect only power cord. If not fixed, Reseat RAM, hard drive. Else, contact local hardware tech.
