I like the Scarlet, so you can go with it. No issues for me, but since you're having problem already, your milage may vary.
@AudioGod build is rock solid, so if you run into some problems, cross check his specs and yours to see the difference. That's usually when problem appear. For example: I have random graphic issues and windows server crashes randomly, but that's due to my XFX 6900XT Bios and not the EFI config.
Btw, do you happen to have usb hub attached somewhere ? I used to run a USB switch and it messed up my sleep big time. Razer products also sometimes messes up sleep and please remove all junky from Corsair and Razer.
