Hello everyone!! The problem in my vaio vgn-nw11s is it restarts or freezes frequently. I have tried different steps to get rid of it but still i m having problems. following are the list that i already performed - cleaned the fan and vents -installed speedfan and check the temp of cpu and its below 50c. - disabled auto restart so that i can get report but it didn't work. -finally gone through the VAIO's hardware daigonistic tool and the result says CPU,MEMORY,HARD DISK all are OK..Also gone thorough windows memory diagonistic and says memory is working corretly.. Finally i completely restored my laptop to the factory settings and still my laptop restarts/freezees!!! Can Anyone help me to get rid of this problem?? Thanks guys!! And i already ran out of warranty as well ..
