The DPC Monitor still shows that my latency is always above about 1000, red or yellow on every cycle.
I used my device manager and disabled/reenabled every device driver. No help. So there are several web sites that talk about DPC. I will go through all of them and perhaps find the fix for my problem.
So far, I updated my video card driver and tried turning off the ticks. No fix yet, but I am on my way toward success. Thank you for your quick response.
