So guys I need some help with my USB peripherals. They are not working when I boot up the PC, despite the fact that they were working perfectly before. I cannot go into the BIOS setup or anything, but when Windows 7 boots up, everything runs great, no problem. Is there any way to fix this ? I had some USB driver problems before and I was actually getting a BSOD, because of that. But I managed to fix the problem. I'm running an MSi H81M-p33 motherboard. Hope this information helps you guys understand...
