a while back i plugged in my joystick into my front panel usb (man, this sounds like a bad porno script written by a nerd) and my computer just went dead. what happened was the capicators in my PSU just up and popped basically. anyway, i cant use usb 2.0 anymore. its enabled in my bios, its deffinetly supported, its broke on all ports so im not plugging it in in the wrong spot. is it possible that there was like, a voltage irregularity but it only effected my usb 2.0 controller? everything else works as expected. my mobo is a gigabyte GA-7N400-L also, i just looked in the hardware manager and theres a question mark next to my Universal Serial Bus controller. i do have the latest drivers for my motherboard and the chipset and whatnot. would i have to install the USB controller seperately then?
