I'm not sure what's going on
You may have to try removing Usb controller devices and let them reinstall
First: Can I double check something
Right click on MyComputer>>Left click Properties
Select the Advanced tab>>Settings under Startup and Recovery
Click EDIT beside "To edit startup file manually, select edit"
Do Not change anything in the file that opens
Give me the name of the text file, is it boot. ini? >>exact name please, I purposely put a space after boot. and before ini so I don't receive an error posting this message
Can you also copy/paste back here the whole contents of that text file
Remember, don't change anything in there
