MacBook Pro (Mid 2010) hard freezes a few seconds after boot

MacBook Pro (15-inch, Mid 2010, A1286, MC371LL/A, MacBookPro6,2)
Intel Core i5-520M 2.4 GHz Dual-Core
2x 2 GB DDR3-1066 (PC3-8500)
NVIDIA GeForce GT 330M 256 MB
SSD

I get hard freezes within seconds of booting (sometimes I need to hold the power button down to turn it off, sometimes it auto-reboots).

Safe Mode works for as long as I want.

I have applied MBPMid2010_GPUFix v0.6.1, to no avail.

I ran two test sequences in memtest86 ('memtest all 2') and everything came back clear.

Any ideas?

    Hi @kingmustard ;! I hope you've made some headway with your issue since you posted. If not, here are some thoughts. 

    Since you mentioned that Safe Mode is working fine, the issue could be linked to a software conflict, such as a third-party app or a service that starts on boot.

    You could try selectively disabling startup items to see if the issue persists. Go to System Preferences > Users & Groups > Login Items, and try removing items to see if the problem is resolved.

    Another option could be a clean install of macOS, if you haven't tried that already. Backup your data first, of course!
