Hi, I've been having a bit of trouble with my setup since I upgraded to Haswell about a month ago. Originally the problem was that once at the windows loading screen the motherboard would power down the USB ports, nothing I did would fix it so I reinstalled windows. That fixed the power down issue but I kept getting random blue screens and when I used a blue screen reader It said it was a USB problem. It seems that the drivers are the cause of the problem because once they are installed the USB ports power down once at the windows loading screen, without the drivers the USB ports are fine. The second problem happened while I was trying to fix the USB issue. For some reason my SSD (Intel 520 Series) wasn't being detected by the motherboard, no matter what I did it wouldn't detect it. I ended up flashing the new bios (F7, I originally had F3), the new bios fixed the SSD issue and installing the new USB drivers off Gigabytes website fixed the USB issue, but not completely. Sometimes on boot the power down issue would still occur but a reset would fix it. Last night I was playing Far Cry 3 and the sound cut out, then about 10 seconds later the computer locked up and all I could do is reset it. Once I reset it the SSD is now not detected again, I've tried unplugging the data and power cables and plugging them back in, I pressed the reset cmos button and have switched the power supply off and removed the battery and it's still not detected. I decided to install windows on my HDD to see if windows would be able to see it but now I've run into the USB issue again. This time there is no bios update to flash and the latest drivers off the website don't fix the problem. When I boot into safe mode, the USB ports work as normal, reboot to normal mode and they power off once at the loading screen. I can uninstall the drivers in safe mode (which I will do now) but I'm thinking I'll have problems with random blue screens again. I ran some SSD life program to tell me what the condition the SSD was in when I first got everything working again and it said it was 100% fine so I'm not thinking the SSD is dead either.
