Definitely sounds like a drive issue. Did you try uninstalling all video drivers on your system, and then installing the 2.7 cats?(they seem to be the best)
-"Don't touch that!!!!!" -ZAPPPPP!- Hehe yet another excuse to upgrade-
Anythign above Cat 3.7 or Set 44.xx is known to give loss of signal errors on some games, as such your best doign what Morpheus Kain suggests and dropping back
Heard it's short but very sweet. I think it's only like 25$ which sounds like a deal to me. If you liked the first I'd say buy it, and if you didn't I'd wait for the bargin bin.
