BSOD completely random and getting worse

Hello everyone!


This is my first custom built computer. I have had it for 3 years. About a year ago very seldomly I was getting the BSOD. I have dual monitors and attributed it to the new graphics card. I went back down to one monitor but have been seeing the BSOD more frequently. I was not using my computer for the past 6 months as I was out of the country... when I got home my husband told me about the frequency and what it was doing. Randomly I get a CPU overheating message but I have 4 fans in proper flow and when I check the temperature it reads fine. It is also set on energy saving not perfomance so I know it is not straining my system. I uploaded my mini dump file. I appreciate any help. I need my pc for work. THANKS!

The device driver has caused a address violation exception, by using a null pointer.
