I followed the guide with the bios for people not being able to boot with usb connected, and I still get the blining cursor in the top left and blankness if I try to boot with my printer plugged in and on (if off it works fine) but I still cannot connect all of my other usb items without it crashing to a blue screen in windows or not boot at all at startup. I talked to tech support and they said to delete the usb root hub followed all their directions and was told it would definitely fix it. Needless to say it didnt. Still cannot plug in more than 1 or 2 usb items without the blue screen crash. This is extremely annoying. Is this a known error or is it just my pc? Its kind of pointless to have a ton of usb ports on the pc and the monitor if you cant use more than a couple. Can anyone help or at least put me at peace of mind? Thanks
