High cpu usage and running low on virtual memory

Cpu runs at 100% all the time
The cpqdfwag.exe runs at the top using 99% and if that process is turned off the next process running at 99% is webdmi.exe and if that process is turned off the next process running at 99% is lcrms.exe.

It is also used to take photo’s and scan signatures and it says running out of virtual memory at times and will not take the photo or complete the scan.
Thanks Peter
