Windows 10: Identify the cause of CPU Spike and crash

I am using a Dell 5490 AIO since May and I still haven't figure out the cause of CPU spike. Now, it is causing a lot of trouble because my PC hang twice in the past 4 days. I checked Event Viewer and it only shows the Event 10010 Skype timeout error after the system crashed.

TiWorker.exe spikes in CPU usage and causes crash

I have done those, but I still have freezes and crashes. Doing the SFC /scannow resulted in a freeze in my computer. I believe the high CPU usage may be causing crashes. Would it not be possible for TiWorker to trigger a crash because of the massive spike
in CPU usage caused by it? These crashes and freezes have only occurred in the last few days, and it seems weird to only crash while TiWorker spikes in CPU usage

 

TiWorker.exe spikes in CPU usage and causes crash

Recently my computer has been crashing a lot resulting in many BSOD's with mutliple different error codes. Some codes include: dpc watchdog violation, whea uncorrectable error, and system thread exception not handled. There is always a major spike in cpu
usage from Windows Modules Installer Worker before each crash. Sometimes my computer will just freeze without crash, and I cannot open or do anything, and must restart my computer. What could I do to fix this?

I run 64-bit Windows 10, and I have no updates available

 

Audiodg.exe Spikes Cpu Usage

Every 5 minutes or so audiodg.exe spikes my cpu usage to about 50% and any audio im playing cuts out and then comes back a second or 2 later. The video is completely fine and it's not a problem with
my USB Headset. audiodg.exe stays at low cpu usage when it's not spiking.

Solutions I've tried:

1. turning off audio enhancements
2. reinstalling lan, and audio drivers
3. turning off HPET
4. lowering the sound quality in control panel
5. DPC Latency checker (no change when spiking)

None of these solutions work. Please help.
