USB error

[Buzzik]

Hi there. I just built a new PC and installed everything on it, but when I try to connect more than 4 USB devices to my PC windows won't boot up. Also my motherboard shows an error code 50(50h) and when i looked up what it means is says "initialize usb keyboard and mouse". I am not really good at fixing such problems that's why I am posting here.

I have
motherboard: GA-X58A-UD5(rev.2)
power supply: corsair HX 850W

PC's arent meant to have that many USB devices externally especially if un-powered. You may need to get a powered USB hub and plug them all into it

I have on the back of my motherboard 4(2x2.0 and 2x3.0), 4 on my case(2x2.0 and 2x3.0) that connected to motherboard, and 2 on my monitor that connected to pc through usb cable. So you actually mean that I can not use them all at a time even they are all connected to a power supply, it sounds wired. What is un-powered and powered? But why when I connect them when windows is running everything is fine?

Well never mind guys I figured it out. The issue was with my mp4 player that has two types of USB connection "msc(ums)" and "mtp". It was set to msc that prevents windows from start up idk why tho. maybe it just can't recognize what device is being connected or smthg.
