--- Comment #1 from Jan Beich <jbeich@FreeBSD.org> ---
Does it happen on other operating systems? Maybe try playing with
CPU/GPU/DRAM/etc clocks in BIOS. Otherwise, try a kernel from newer FreeBSD
release[1] without upgrading.

[1] The kernel is backward compatible with old world by default (see
COMPAT_FREEBSD* options) and the graphics stack doesn't have any userland
components that depend on a specific FreeBSD version execept for ports bloc=
ked
by the ancient toolchain in base. OTOH, installing world opens a can of ABI
worms unless all ports are rebuilt e.g., after base r318736.
