Ok guys I have this new system that I built and just recently it has been chopping and lagging real bad when I try to run a program (something basic like winamp) and then it will just lag out real bad when I try to open more than two files/folders. I am thinking that it could be Windows XP. I have the service pack??? Or is it possible that it could be my hard drives. I have defragged them! Specs of the system: Antec True Blu 430 Watt PSU, Gigabyte GA-SINXP1394 MOBO, 2X512MB Corsair XMS PC2700 DDR RAM, 2XWestern Digital 120Gb 8mb cache 7200 rpm hard drives, Radeon 9700 Pro All in Wonder, Pentium 4 2.8GHz (3.08GHz at 146FSB; Scored a 15741 in 3DMark2001SE before problems going to bench again and then post result). I have a CDRW and a DVD Drive, using on board realTek sound. Well I am sureI have all the latest drivers too! Any ideas ???? Thanks ElpiercoOh current CPU Temp 40degrees Celsius(?)
