Ok just wanted to pitch in here with a different method you might want to try in order to fix this game. I have tried all mentioned methods and disabling V-sync, and no AA in the graphics control panel seemed to have sorted the random crashing to the desktop. Anyway my biggest issue was with trying to go into a particular area that would lock the game up. Im not talking a cave or inside anywhere I mean just randomly walking in the wilderness, it was like the game just couldn't stream the next part and so would freeze the game. Overall this game has some serious errors when used on a PC. I had updated everything and made sure the game 'should work', I came to the conclusion this is something wrong on the game's programming end! But then I remembered the issues with installing this game on the xbox onto the HDD? Couldn't stream the HD texture's properly... so this got me thinking is this an issue with the HDD and it communicating the data to the game? So I have gamebooster installed and I hit the 'analyze' button. This scanned my computer and came back telling me that I had a HDD / Bad block .... I think there were more than ten! So I ran the cmd >>>> chkdsk /R You can find out what this does here : CHKDSK Essentially it scans your hard disks and fixes errors. This can take more than an hour and it is highly recommended you make a back up of your hard drive before you do this! I restarted and the process of scanning and fixing began and to my amazement near the end of the process it came up and said the following: 'windows replaced bad clusters //skyrim/data/sk237~1.BSA' 'windows replaced bad clusters //slyrim/data/sk44DE~1.BSA' Long and short of the story it fixed my game :thumbsup: I have played around 4 hours now and passed through this 'invisible' lock up area's without a hitch! Anyway I hope this help's some of you out there!! If this could be of use to people please spread the word! Ste. SYSTEM SPECS: windows 7 phenom x6 2.8ghz 8gb DDR3 GTX 460 1GB
