Since no make, model of the machine I can guess that someone installed 7 but forgot motherboard drivers. Windows 7 is better about drivers but not always there.
So here's the question. Does the machine's maker tell you how to install Windows and all the drivers after?
Here's my question. Why didn't they?
I was trying to install ps3 controller usb drivers and after reboot something happened cause it works in bios and win7 system repair but once windows (safe mode and last known good) all usb immed. power down.
Thanks for your help! win 7 x64 btw
