That's a GPU lockup, but if your num lock / caps lock starts flashing, it perhaps indictates a kenel panic. Can you check the output from dmesg next time. (Or review back in the /var/log/kern.log).
As this started happening after a hardware upgrade, can you let us know what components inside the computer were replaced / reseated in the upgrade? The issue could be hardware related.
