i think i may have found the cause of my problems,i just updated to the latest nforce drivers and i was getting a bsod as soon as windows started,it happend in safe mode too when i included network support,i tried normal safe mode and it worked fine! i did a system restore and uninstalled my nvidia forceware network acccess manager then updated the nforce driver again,so far i havent had a bsod yet i also checked the large hdd to see if it needed a defrag and i was amazed how overdue one was,so far i havent had another bsod and my hdd access has been a lot faster
