Hi folks. After testing my computer for several days, I think NOD32 is freezing my HL2 and CSS games. I have disable all kind of program and only NOD32 was working.I got this message: Popup of applicatory: Counter-Strike Source: hl2.exe - Error of applicatory: The instruction in "0x2417783b" make reference to reference the memory in "0x00bc2ed0". The memory could not be "read". After I disable NOD32, I could play fine. Any ideas ? Best Regards, DonKid.
