I just got a Dell XPS 410 yesterday with the Intel Core 2 Duo processor, 1 GB memory and everything is good. I installed HL-2, UT2003, and CS. Everything works crystal clear except my CS. When i load it an Error box pops up. I looked up FAQ on forums and they say it is a common error but hard to fix but there is a difference between the common error people get and what i get. My error pops up and reads- The instruction at "0x0#####" referred memory at "OxO#####". The memory could not be "written". Click Ok to terminate. That is mine, but the common error i found on the FAQ says the memory cannot be "read" rather then "written". Does anyone know what this means? I ran several system scans and fully scanned my memory unit. Still no clue. Called Dell support system, they have no clue either. What could it be? Also if i understood what the message meant, like the difference between "read" and "written" in terms of the memory...then maybe i could figure out the problem. But i have no clue.. help!
