Can't boot anymore – "PXSX cannot assert wake from D3cold"

So, my friends hackintosh was running just fine since the last issue, which involved switching to clover, except now it hangs at "PXSX cannot assert wake from D3cold". Recovery works more or less fine, it just takes a bit to start up but is otherwise normal.

I've tried a variety of different bootargs (-x -f, among others), I cleared the boot drive so it had 5 gigs free (it only had 400 mb before I did that.) and I cleared the cache.

I would really appreciate any help you guys could give.

Here's the part list
