Dell Dimension 3000 crashing when connecting to game server.

My computer is crashing when i connected to a Counter-Strike 1.6 server. It gives me BAD_POOL_CALLER. error code3 0x000000C2. I have already checked the firewall, and the game has worked before.I am attaching a couple of minidumps. It has happened before though, so im not thinking its the games fault.

btw the CPU is Pentium(R) 4 2.8 GHZ
with 512 mb of ram.
the OS is XP Sp2.
I cant tell what the rest of the parts are, but i believe the graphics are integrated intel.
