Hard to say...what's the vcore reading at load? Your cpu is idle in that screenshot.

I know I can prime at a vcore reading of just less than 1.25v load at 4.5 ghz.
If you're completely locking up at 4.2 ghz and 1.20v before you can even run any programs, then that definitely isn't a good sign, since you usually need at least 0.05v higher if you freeze right after windows loads...

Can you prime at 4.1 ghz with a LOAD vcore of 1.17v? (no idea what you have to set it to in bios to do that at load).
