Hi, I'm new here (new to forums in general) and I really need help with my computer.

Sometimes it freezes for a small second, like stuck on a short repeat? At first, it happened only to audio, but now it's happening to video as well.
I've updated my nvidia and dell drivers and disabled power throttling like LatencyMon suggested but the hiccups only got more frequent. LatencyMon suggested updating the BIOS but I'm scared of it getting a hiccup midway and messing something up. Any idea what could be going on?

My specs (from speccy):
CPU: Intel i5-7300HQ @ 2.50GHz
RAM: 8,00GB Single-Channel Unknown @ 1196MHz (17-17-17-39)
Motherboard: Dell Inc. 0MK77P (U3E1)
GPU: GeForce GTX 1050 Ti
SSD: 238GB SAMSUNG SSD PM871b M.2 2280 256GB

LatencyMon report below!

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.

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): 1009,60
Average measured interrupt to process latency (µs): 6,336278

Highest measured interrupt to DPC latency (µs): 1006,20

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: mbamservice.exe

Total number of hard pagefaults 97083

Given that UEFI/BIOS is the foundation on which all else rests, if there are updates available from your computer's OEM those should be applied, promptly.

Your hiccups won't prevent that from completing successfully.
 
I update the BIOS and it still freezes.

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.
