I was having the same problem; my specs were up to par (if only just), but my system would lock up or shut down after a few minutes of HL2. I tried
everything, from updating my video drivers to double-checking my RAM, to no avail... but I finally figured it out: the antics of Gordon Freeman were
overheating my CPU.
Check your CPU fan for obstructions, and if you have any extra case fans, make sure those are working properly too. If there's a heat sink over your
CPU, make sure it's clean as well; you might have to take the fan off to do this. This is what solved my problem, and there's a slim chance you
might have the same one... good luck, nobody should have to live without a Gravity Gun.
