Welcome
You have given us 3 dump reports
2 indicated that its the Nvidia driver that must be updated
Nvlddmkm.sys file description NVIDIA Windows Kernel Mode Driver, Version 194.94 NVIDIA Windows Kernel Mode Driver, Version 194.94 NVIDIA Corporation

The third was code 124 which indicates hardware. Update yourNvida driver and see if the BSODS continue. If they do post the new report.
