I bought the Samsung R780 about two weeks ago and its starting to freeze up already. This experience isnt new to me either, I actually returned my earlier R780 because of the problem. Anyways, on this computer i decided to only install very well know programs ie: itunes steam things like that, well it still froze. I did a full system restore and only installed Noroton security, and Spyware search and destroy. Yet again it feezes up. I have done many regesitry cleaners, virus and spyware sweeps, disc defragements, i wanted to see if it was the temperature and i walked in today my room maybe 60 degree F and turned it on for the first time today and it froze within 5 minutes. I have done both Samsung and Norton system diagnostic tests, nothing wrong with that either. I just did a harddisk scan and every thing is alright there. I dont know what else to do. Out of the 40 reviews on best buy there are none that say there is a feezing issue, so do i just have terrible luck or something?
