recently changed my previous motherboard and installed a new one. but all the 6 ports on the back are sometime working and sometime just hangs and stops working. and the front 2 usb port were also working properly first but then one stopped working. if I use a pendrive in that port the light just consistently glows in that port which was first working but not now. please help me tried sfc /scannow and it shows Windows Resource Protection did not find any integrity violations. tried Belarc advisor and in report under operating system it shows windows 7 ultimate , but the newly installed windows is win 7 professional 32 bit. and my windows version was as follows from previous to new on "old" motherboard: windows 7 ultimate 32bit -> win 10 enterprise 64bit and current windows on "new" motherboard is : windows 7 professional 32bit
