I have just recently built a computer for my younger brother. it is running on 256Mb DDR ram, amd sempron processor and motherboard and 40Gb hard drive. I have installed Windows xp professional edition on it.
the problem is that whenever my brother installs and plays a game on it he gets the same error message come up (im not sure what it is as i havent seen it) after about an hour of playing on it. it says something like 'access denied, memory violation and then gives a code number. the system then crashes.
i have tried replacing the memory but this has been to no avail as the problem occurred even then. i have been told that it could be a motherboard fault bu i am confused as i think its a software fault. can somebody please help me and shed light on this as to what they feel it could be?
