I don't know how to put this or where to put this thread cause I am not aware what is exactly causing the problem. A few days ago I changed my motherboard with a slightly new model (from G41M p26 by MSI to G41M p33 Combo also by MSI) because my old one died for an unknown reason (PC refused to boot with it). I've installed the new motherboard in and also bought an additional SSD for storage and plugged it in the second SATA port, having an SSD on first port with the OS already. After reslotting every component I booted the system and it works but with a problem. The system boots slowly, way too slow for an OS on an SSD (as in it hangs for around a solid minute on the black logo screen with the looping circle) and by the looks of it I have high DPC latency problems, like really high. There are a lot of audio crackling noises through my headphones, tried 2 games and I had really volatile FPS (as in it would go from 80 to 30 to 70 to 15 and so on while completely not doing anything in the game). Here's the stats as taken from Latencymon after letting it run for a few minutes with me doing minor background activities.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. 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 0:05:40 (h:mm:ss) on all processors.

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): 77873.647964
Average measured interrupt to process latency (µs): 55.395104
Highest measured interrupt to DPC latency (µs): 77865.114539

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: setuphost.exe
Total number of hard pagefaults 3321
Hard pagefault count of hardest hit process: 1171

I just don't know what to do it drives me crazy. I tried by disabling drivers one by one until I found the culprit to no avail, cleaned and reinstalled the GPU driver still nothing, disabled superfetch and changed power options plan settings and still no change. Ran memtest86 and it returned no errors. Unplugged devices from the computer (headphones, mouse, keyboard). Worked with a few settings in BIOS and still nothing. All drivers are up-to-date, BIOS is up-to-date, I even reinstalled OS (fresh install) and still no change.
System information:
CPU: Xeon E5450
Mobo: MSI G41M P33 Combo
GPU: GTX 650
RAM: 2x4 DDR3 1333mhz (running at 1066 mhz according to BIOS)
PSU: Segotep SG D600SCR
Storage devices: 120gb Patriot Burst, 480gb Kingston
OS: Windows 10 Pro Edition, 10.0, build: 16299 (x64)
Mouse is connected through USB Port in the back.
No additional sound cards or PCI-E cards or anything like that.
When I boot using Safe Mode, the slow loading problem at boot doesn't seem present at all but according to Performance Monitor, there are still latency problems even in safe mode.
Note: I do realise that the Xeon CPU is an LGA 771 CPU and the motherboard is a 775 socket. I use a modded Xeon. I've applied the mod according to this tutorial:
https://www.delidded.com/lga-771-to-775-adapter/
Could this be the problem I don't know, but the old motherboard had no DPC latency problems or such, it was working perfectly fine with the same mod applied. Please help me on this problem I got no answer or way out at all. Could it be that I need to use Win 7 instead of Windows 10? I don't know.
