All Dawnguard DLC causes crash to desktop....

[BumbleBia]

So I recently got dawnguard, was on sale so figured why not, I am enjoying the game and enjoying modding the hell out of it.

So all my existing mods are fine. I can launch the game no problem, but I try to install any new mods I get the crash to desktop on title screen issue.

So these are the following mods I got, all of them, together, alone, any loading order, cause the crash.
http://skyrim.nexusmods.com/mods/29803
http://skyrim.nexusmods.com/mods/9717
and
http://skyrim.nexusmods.com/mods/23491

For those not wanting to click links, its basically the Dawnguard versions of better vampires, be both werewolf and vampire, and the Dawnguard Patch unofficial.

I have no idea what I am doing wrong, if anyone has any suggestions, or had this issue themselves.
Again all the mods I have had before I bought dawnguard were fine, anything I get now causes an issue.

Same thing happen to me. I have only HD patches, and Dragonborn DLC. Game still crash no matter if reinstal or by selecting off Dragonborn DLC or HD patches.

haha, thanks for the response.

I stopped playing Skyrim a few months ago, and when I went back I pretty much had to do a fresh install because every mod was so far out of date the game wouldnt work at all even after updating.

I played about 130 hours of Skyrim with just the Dawnguard and Hi Res Texture packs and had not one crash, ran perfectly. Suddenly I download Dragonborn and Hearthfire and every single time I load my game it crashes within a few minutes, maximum has been 5 minutes. The screen freezes and I have to reboot. Tried unsubscribing every mod, reinstalling without any mods, playing with the Dragonborn and HR packs turned off, all to no avail. Anyone got any ideas?

Waldo, try to use Nexus Menager to look if any mods are left(hidden) if that doesn't work try to look at your main folder in c:/.../Steamapps/common/Skyrim and search for files in Voice and Strings(files should be name after their DLC for example in voice u should have Dragonborn.esm folder etc. if one of them is missin try to veryfy files with steam or copy it from a friend)

Sorted it out. Downloaded the AMD Radeon Catalyst Control Center so I could change my graphics card settings, crank up the fan, etc. No more freezing at all, even with all the DLC active. Now to put my mods back on.
