Blue screens with different repeated errors

Hi everyone!
I use a Sony Vaio SVE1713M1E laptop and at some point I started getting this message on windows 8.1 during start up:
iolorgdf32 program not found - skipping AUTOCHECK
I am not sure if that message has to do anything with the following, but soon after that, Blue Screens started to appear and restart the laptop with the following messages:
NTFS_FILE_SYSTEM
NTFS_FILE_SYSTEM (Ntfs.sys)
MEMORY_MANAGEMENT
KERNEL_DATA_INPAGE_ERROR
SYSTEM_SERVICE_EXCEPTION
SYSTEM_SERVICE_EXCEPTION (tcpip.sys)
These Blue Screens always cause an autorestart.
This happens at least once per day, to 3 or 4 times per day! It drives me crazy!
The MEMORY_MANAGEMENT message is the most common one so I did a memory test but no errors were found.
Then, I tried to do a disk check but it always gets stuck at 15% for hours, so I leave it to it and the next morning I find it on the start sreen (probably after a restart caused by a blue screen, not sure). I have tried to do that at least 20 times, but never succesfully.
I am no pc expert but I have search in the forums and I saw that noone else has this problem with the multiple different errors causing the blue screens.
Any ideas?

I have uploaded the DMP files in dropbox: dropbox.com/sh/8c2t3r6ud52oilv/AABtmDXFO0pcoPVDZv0WQMlca?dl=0

Thank you in advance!
