Q: os 10.10.5 showing as system but won't open and wifi keeps dropping

This problem only occured in the last couple of days. When I open my iMac I get a line of text

panic (cpu caller xffffff800a863cb1): "unable to find driver for this platform: etc etc

I have tried a safe reboot and used utilities to check my hard drive to no avail, all coming up okay. Also my wifi connection keeps dropping. What is happening here??

iMac, OS 10.10.5
