Going from the latest dump backward, the first listed the cause as being aswTdi.sys (not certain, but it appears that is part of Avast AV), the second just says memory corruption, the third...unknown, fourth ntfs.sys, and all that followed simply said unknown.
That doesn't leave much to go on, except the first mentioned. Whether there is any relationship between the known and unknown BSODs would only be a guess, but I would try uninstalling Avast. if it is installed,and see what happens then.
