Hi batista v
The minidump file that you just posted indicated stop code 44, this is usually device drivers issue. The bugcheck indicated it was caused by USBport.sys driver. I would suggest you to go Computer-->Manage-->device manager, under USB list, uninstall all the device, then restart your machine. After restarting, window will automatically re-install all the drivers. Hopefully it will fix the problems.
Here is old driver related to usb
Code:
usb2vcom usb2vcom.sys Wed Dec 21 10:32:55 2005 (43A8CCE7)
BUGCHECK:
