Hi, When I plug a USB 2.0 device into my computer, the mouse and keyboard stop working. I have this problem for a year now and now i'm thinking of buying a mp3 player. But the USB 2 on my computer doesnt work! I tried installing all the drivers for my albatron KM18G Pro motherboard but that didnt fixed it. I was suspecting maybe there is a problem with my power supply. It's only 300W. To all the computer whiz in this forum, please help me out. Thanks.
