I played Skyrim for like 3 weeks, and i have no problems. But yesterday the problems starts. First of all, in a quest (the one for the jarl of solitude, the horn to talos stuff) when i first fast travel, the game crash. I tried again a few time, no luck. So i tried to go near the location and go foot, but when i come close it crashes again. I solve simply waiting 12 hours in game, and i finally done it, but i don't know why. But that was only the start. Another quest, the next i've done, the one for the Imperial to deliver the axe to Ulfric, when i've done it i coudn't speak to the Imperial General at Dragonreach to end the quest. So i read that another one had my problem, and he solve it simply doing another quest from the main storyline. So i start it, but then this problem arrive. I have a huge lag spike every, precisely, 1 minute. I'd chrono it. 60 seconds. The strange thing it is that the dialog and sounds didn't stop, but everything else it's freeze for about 4 seconds. Then, everything is fine again, i see lyps moving for recuperate the dialog lost, and everything is fine... for 60 seconds. I don't understand why now there is all these stuff. I put them together in this thread, because maybe these problems have nothing to do with each others, but it is strange that they start about the same time. Any suggestion?
