DPC Latencymon - Need Help


I’ve been running into numerous issues with my rig and I am looking for someone who is knowledgeable and trustworthy who I can hire. My rig likely has a hardware issue in addition to DPC latency problems, but I’d like to give it a thorough diagnosis using xperf, or other diagnostic methods. This issue could reoccur on a new rig, so I would like to make friends with a technician in case I need help in the future. A few of the issues listed below:

-BIOS sees 60GB RAM and not 64GB (8x8GB sticks, and on my second set of corsair ram after the first set had a memtest error)

-One USB 3.0 port works, but the other one does not. There are a few other ports directly on the back of the motherboard that don’t appear to be working. For instance, if I plug in an external 2.5 SSD, or other device, it appears to send power to the device but the device driver does not install.

-Some USB ports are not working or losing power at times.

-Drives are slow to populate in windows explorer

-EFI boot partition is on the wrong drive. Somehow my system will not boot without 2 drives plugged in, one with the OS and the other with an EFI partition.

-DPC latency spikes on latencymon. Hardpagefaults is always maxed out. suspect drivers are usually storport.sys, nvidia drivers. Storport got up to 8ms max execution time.

-Device manager will take forever to display, and often will crash without warning, or with “Microsoft Management Console has stopped working.”
