So I was experimenting some freezes on my Alienware 15 R2
Its very unpredictable but happens every 40 min - 1 hour of using it, the display freeze out only for 2 secs, and if I have sound the same thing happen.
These are my Specs:
Windows 11
Ram: 16 GB
SSD 128 + HDD 1 TB
Nvidia 980M

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. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 1:33:44 (h🇲🇲ss) on all processors.

SYSTEM INFORMATION
_
Computer name: PCWOLF
OS version: Windows 10, 10.0, version 2009, build: 22623 (x64)
Hardware: Alienware 15 R2, Alienware
CPU: GenuineIntel Intel(R) Core(TM) i7-6820HK CPU @ 2.70GHz
Logical processors: 8
Processor groups: 1
RAM: 16250 MB total
_
CPU SPEED
_
Reported CPU speed: 2712 MHz
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): 2225.80
Average measured interrupt to process latency (µs): 7.297040
Highest measured interrupt to DPC latency (µs): 719.0
Average measured interrupt to DPC latency (µs): 1.940636

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.

Driver with highest DPC routine execution time: ndis.sys - Especificación de interfaz de controlador de red (NDIS), Microsoft Corporation

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: msmpeng.exe
Total number of hard pagefaults 38685
Hard pagefault count of hardest hit process: 9195
Number of processes hit: 248
