My game keeps freezing upon loading any of my saves. I can move around for a second or two but instantly freezes. Have tried loading other saves and this is still a problem. Ive had this game for years and never had this issue. Now its occurring.

Also, im not using any mods.

I am having the same issue, my game freezes after just a few seconds. Please help

Any changes made to the computer like an update to the OS, change in video card drivers.

None. I played it for a few hours. Turned my computer off, left on an extended weekend, came back last night to this malarky.

Does the game freeze when starting a new character.

Yes.

Please run dxdiag.exe and post the full report in spoiler tags. Also it might help to know which version of the game you have is it a steam version or retail disk.
