Just had a look through your dumps and they are all the same bugcheck code 0x50 PAGE_FAULT_IN_NONPAGED_AREA have a look here for a bit more info and likely causes
http://www.carrona.org/bsodindx.html#0x00000050
All dumps report the faulting driver to be 1160x64.sys, have tried googling it but i have no idea what this is or what program/software it belongs to, one thing you could try is to locate the driver in your windows folder and temporarily rename the file ext to .bak to stop the driver loading see if it helps your problem, worst case it will throw an error if it does simply change back but the error may give you an idea of what the driver belongs too.
A few of the dumps mention usb i would try unplugging/disabling any usb items you are using to see if it helps
AV can be also be factor
Also noticed these older drivers on your system would recommend updating them if possible especially those that are over 12 months old
