I just built a new computer i installed windows xp. I get send and dont send errors all the time. 50% of the programs i try to instal have a failure. sound doesnt work in games. I dont know what to do. Ecs the motherboard said to swap cpu. i did that same problem. then they said to change the ram and reformat. even though the ram i got is suppost to be supported by the mobo and i rreformmated my harddrive like 5 times and still got the same problems. i even rebooted 1 time and i got a whole bunch of artifacts on the screen. what do i do?
