My disc is scratchless and fingerprintless and i have had no problems before but now when i start the game it takes about 5 minutes to load the add ons then when it works no matter where i goto i cant play more then two minutes without it crashing ive deleted hundreds of saves and tried multiple accounts but ever since i downloaded dragonborn i also realized i cant even enter my hearthfire houses other room because the first step i take into the house that isnt part of the main foyer sends the game crashing on me so all my items in the other side of my hearthfire house are trapped, any suggestions ;/ i have some really nice items in there and id really like to get them out so i can move to another house and see if that helps
Did you try reinstalling any installed skyrim content from the harddrive? (Skyrim itself if its installed, dawnguard, hearthfire and dragonborn). Clean the drive from any skyrim content and start from 0 (you can save your old saves on a USB memory stick for now).
^This^ has been the fix of choice so far. If there are a lot of saves on the HD, and the cache is full, the DB download doesn't always mesh well. As the OP said, save to mem stick, delete and re-download. Also clear your cache at least 3 times. (only takes seconds) This fixed many issues for me. This process really doesn't take a whole lot of time and is well worth it. Good luck!
