I posted on this site not too long ago that my Acer desktop t180 would not boot properly. I went through nearly EVERY troubleshooting step. Come to find out, when I plug my keyboard or mouse up to ONE of the usb ports in the back of my computer, it will boot properly. If nothing is plugged into this usb port, my computer will stall on the logo Acer screen and will not move. When it finally boots, it says "unknown device installed" on one of the usb ports and the only two devices i have in the usb ports are my keyboard and mouse not even plugged into the suspicious one. so do i need to disable this usb port to make it boot properly every time? or possibly disable the whole cluster of usb ports on the back of my computer? i wouldnt be apposed to that because i only use the ports on the front of my computer, but i wanted to make sure that this would work before i tried it. thanks in advance
