Hi All,

Hoping someone can help,
I have been using my system for long time now.
Rampage IV Formula, 3930k, 16 gb G.Skill, OCZ SSD

I was using Version 12 Bios up until now. I decided to update to the new CAP as I want to upgrade to Windows 8.1.
The conversion went fine and upgrade to version 48 was also fine, I loaded windows 8.1 as I would normally load windows, everything was fine....to perfect you could say.
It wasn't until I started to plug in my USB devices and restart the computer that I noticed issues.
Bios loads fine, then as it got to the windows load screen that is when it was locking up, if I unplug the devices and leave just the wireless Keyboard/mouse in it boots.
First I blamed windows 8 (lots of swearing ). Believing that was the problem, tonight I have wiped the system and reinstalled Windows 7 x64 Pro. To my surprise I have the same issues.
I then dropped back to Bios Version 45 and cleared the CMOS, still the same issue.
This is not the first time I have reloaded Windows over the time of owning this system either.
So this computer is my sim racing rig, the devices that I have had plugged in and had no problems with now don't work at start up, in saying that, once the computer has loaded, I can plug all the devices in and they all work fine

The devices having issues now are, G27 wheel, Fanatec Pedals, Frex shifter, G27 Shifter.
One other note, if I plug a couple in through a powered 4 Port USB device they work at start up, but startup is slower

Please help
Regards
Shane
