I have lots of USBs going into my computer all USB slots are occupied and I also have a USB hub so I can get all of my USBs connected. I built this computer about 2 and half months ago it was fine with all USBs occupied but a couple days ago when I turned it on it would get stuck to the splash screen. I unplugged every USB connected then it would load up fine but I have to do this every time I turn on my computer. Any solution? Maybe I need a higher wattage power supply? A USB hub that has a external power supply?
