ok....

I can build a model with no problems untill suddenly i will select an edge, or a vector and the system will trip, asthough the cpu is working, then it will dong at me and then it will freeze completely requireing a total reboot, it seems to happen more while i'm in edge mode or vector mode... i'm running maya 6.5, i had no problems whatsoever with 5 but this problem is so annoying its stopping me modeling completely. thanks to anyone in advance if they have any suggestions that may be of help!
