I recently upgraded my PC from that Pentium 3. Finally eh? Like the title says, I have been having a problem with HL2 and CS:S randomly crashing, hanging the system, and rebooting it altogether over the past week. I was stuck with no path to a solution, until about 10 minutes ago I finally got an error message. See attached image. Also attached are my current specs. I'm hoping someone can point me in the right direction. I'm contemplating reinstalling Direct X and my video drivers.
