Hi, I just updated from windows 7 to 10, and then formatted and installed update 1511 of windows 10. Also had no issues with dpc latency while using windows 7. I've tried everything and haven't been able to resolve this so any help is much appreciated, thanks.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: DESKTOP-LBCJT64
OS version: Windows 8 , 6.2, build: 9200 (x64)
Hardware: P5E-VM HDMI, , ASUSTeK Computer INC.
CPU: GenuineIntel Intel(R) Core(TM)2 Quad CPU Q9450 @ 2.66GHz
Logical processors: 4
Processor groups: 1
RAM: 4095 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 320 MHz
Measured CPU speed: 1 MHz (approx.)
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 439.056298
Average measured interrupt to process latency (µs): 3.854942
Highest measured interrupt to DPC latency (µs): 429.775953
Average measured interrupt to DPC latency (µs): 1.350544

Highest reported total ISR routine time (%): 0.040874
Driver with highest ISR total time: ataport.SYS - ATAPI Driver Extension, Microsoft Corporation
Total time spent in ISRs (%) 0.080296
ISR count (execution time <250 µs): 366421
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 0
ISR count (execution time 1000-1999 µs): 0

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.
Highest DPC routine execution time (µs): 256.5150
Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation
Highest reported total DPC routine time (%): 0.067026
Driver with highest DPC total execution time: ataport.SYS - ATAPI Driver Extension, Microsoft Corporation
Total time spent in DPCs (%) 0.365580
DPC count (execution time <250 µs): 966716
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 2
DPC count (execution time 1000-1999 µs): 0

DPC count (execution time >=4000 µs): 0

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: chrome.exe
Total number of hard pagefaults 9667
Hard pagefault count of hardest hit process: 6185
Highest hard pagefault resolution time (µs): 2382318.45250
Total time spent in hard pagefaults (%): 9.162231
Number of processes hit: 30
