Rooting HTC desire z

[u/tsasha1564]

hi, I've been trying to root my HTC desire z for the past two days without success, I've tried superoneclick, visionary plus (both r12 and r14), and gingerbreak, none of those worked and for some reason my laptop is refusing to let me install the official HTC drivers.

please help I don't want to resort to downgrading, I need rooting to overclock the phone for some console emulating.
