Half-Life: Source is the original Half-Life game with some Source effects (reflective water and ragdoll physics i think).
I played Half-Life 2 at 800x600 with low settings on a 32Mb Geforce 2 MX 200 PCI (basically one of the slowest cards made after the year 2000) and it was playable. Half-Life Source should work fine, especially on a card like the 6200 (which is probably a dozen times faster than the mx 200).
Its most likely a driver problem.
