EDIT: I suppose I'm trying to understand two things, is it 'normal' to get a few hundred pagefaults when loading up programs? The other part would be to understand if getting ~100k ISR count for hal.dll a minute is normal. I use a Wireless N USB adapter in the front of my case in a USB 3.0 slot for the internet. When this is disabled I still get pagefaults but the Latencymon report comes back fine with no high reports of latency although the ISR counts are roughly the same. It is currently my only means of internet in a 3 story building. 

 
I also just want to add performance wise my PC seems entirely stable. I replaced the HDD this week and that seemed to be the huge cause of any problems, but since numbers wise everything in LatencyMon looks the same I just want to make sure there isnt anything else wrong with my machine currently.
 

I previously had a machine with nasty pagefaults where the main culprit was my HDD was actually failing. I received a new SSD this week and reinstalled Windows 7, since then things have been insanely faster. I went from very low settings in multiple games with hiccups to max settings. It's really depressing how long the bad HDD had been bottlenecking my performance and I was in denial.

ANYWAYS, Latencymon posted below as well as an xperf going to be pasted. Would love any help on where to look next, I've installed all drivers I could think of. SSD has been updated to most recent firmware, Intel Speed Tech has been disabled in BIOS and the bios is up to date (Sabertooth p67 3602 version). High Performance has been selected in Windows as well.

CONCLUSION

Your system seems to have difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. LatencyMon has been analyzing your system for 0:02:02 (h:mm:ss) on all processors.

SYSTEM INFORMATION

Computer name: TRISTIANLEW OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64) Hardware: ASUSTeK Computer INC., SABERTOOTH P67 CPU: GenuineIntel Intel® Core™ i7-2600K CPU @ 3.40GHz Logical processors: 8 Processor groups: 1 RAM: 12255 MB total

CPU SPEED

Reported CPU speed: 3407.0 MHz Measured CPU speed: 2859.0 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.

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): 1115.986248 Average measured interrupt to process latency (µs): 2.764362

Highest measured interrupt to DPC latency (µs): 182.091456 Average measured interrupt to DPC latency (µs): 0.893639

REPORTED ISRs

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 209.179043 Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0.033012 Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0.065645

ISR count (execution time <250 µs): 153822 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-999 µs): 0 ISR count (execution time 1000-1999 µs): 0 ISR count (execution time 2000-3999 µs): 0 ISR count (execution time >=4000 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): 270.250073 Driver with highest DPC routine execution time: tcpip.sys - TCP/IP Driver, Microsoft Corporation

Highest reported total DPC routine time (%): 0.038182 Driver with highest DPC total execution time: USBPORT.SYS - USB 1.1 & 2.0 Port Driver, Microsoft Corporation

Total time spent in DPCs (%) 0.133808

DPC count (execution time <250 µs): 567636 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-999 µs): 1 DPC count (execution time 1000-1999 µs): 0 DPC count (execution time 2000-3999 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: svchost.exe

Total number of hard pagefaults 343 Hard pagefault count of hardest hit process: 89 Highest hard pagefault resolution time (µs): 61875.318168 Total time spent in hard pagefaults (%): 0.042098 Number of processes hit: 11

... is it 'normal' to get a few hundred pagefaults when loading up programs? ...

 

Yes, perfectly normal the first time you load up a program, when it has to be read from SSD/HDD.

 

If then you close the program and (now that it has been cached in memory after the first time) you open it up again, it will be read directly from memory and you'll see little or no 'hard page faults' in Se7en's ResMon.
