That particular service is not in W10. It is a service from an earlier version of Windows but the others still apply.
As you proceed with these attempts to fix, have you removed all peripheral devices from laptop? There shouldn't be any headsets, USB connections, etc.. connected to the laptop.
Nice to read you got the Nvidia software working. I may be absent for the next two days but I will keep researching for you and post when I can.
Let's try this.
Access Services again, find Windows Audio, Right click on Properties, and select the Dependencies Tab.
On the Dependencies Tab make note of those Services that must be ON (Automatic) and insure those Services are set to Automatic. When checking those Dependent Services check their dependencies as well.
If this doesn't work you may want to access Control Panel, select Programs and Features, and uninstall Realtek drivers. Run the CCleaner, and restart computer. Windows will download drivers. Try this first and then check for any updates.
You may also decide instead to download the Realtek drivers onto the Desktop from Dell, disable automatic Windows updates, and then after uninstalling Realtek drivers in Programs and Features, run CCleaner, restart computer, and install Realtek drivers from Desktop.
Also on your Desktop referencing your Apps. The third icon to the right from the trashcan... is that and another similar icon Registry saves? Have you made any Registry changes to your system?
< 2) Using administrator privileges, at the command prompt type in sfc /scannow.
This was good to try, but you reported ... it said no problems found.
If you are not going to do a Windows clean-Install, then I suggest you at least try a Repair Install.
The reason I previously said to jump right to a "clean Windows install" (Nuke-and-Pave) is because you will likely have to do it anyway ... as one last attempt to fix it before you proceed to getting the motherboard replaced with a working one. But who knows, you might get lucky so the easier Repair Install is worth a try.
Yeah.. I really want the clean install to be the last final no other choice option... cause I'm pretty sure I will screw up the delicate process of selecting drivers and etc... (me being fresh meat for windows).
But I'll try the repair install
Checked services are all automatic (before and now) -complete
The registry saves are from cleaning the registry from Cleaner, it was recommended so I just left the option for it to do so... unless it was the wrong thing to do?
Oh. Yes I've reinstalled that realtek drive multiple times from dell and that doesn't really solve anything
Btw, I think you're on to something about windows for my system being possibly glitchy or corruputed. Ever since I brought my alienware, it's been having all these problems:
1) Couldn't connect to any internet via browser for a few weeks because some program in windows decided to malfunction and permanently crass like windows audio (fixed after I restarted couple of times.. werid.)
2) (ISSUE, Don't know how to solve.. nothing on internet, planning to post this after I fix sound) I am currently still plagued by this lag freeze ranging from 3 min periods to 2-3 hour period where my screen and mouse suddenly freeze for 1-3 seconds then it lags a bit and continues... x.x (sound continues though- definitely not crap internet). Btw, the cpu and gpu aren't overloaded or anything that sort.. it;s just me casually browsing the web and the freezing happens.
3) (sometimes.. often enough.. Windows keeps on over riding my settings of no windows update or allow 'steam to make changes' : have to relaunch steam game multiple times for example hoping for prompt to accept my command for it to work. AND yes I am admin.
Yeah... that's all the problems i'm aware of so far if you aren't counting the:
All videos now insta crash on me when I try to play them... with no sound or not
If they don't crash.. windows will hold the space bar for me gently without letting go (video stops and plays in 1 second intervals) till I close the tab. ( My space bar isn't broken btw).
Generally.. right now I have to say my 4 year old 2011 mac book does a better job at accessing the internet and etc. than my disabled fresh brought alienware
Just a hunch.. I use webroot anti-virus.. is this anti-virus part of the reason for my system error cause I had a dozen of windows system files in the quarantine + some steam files labelled as virus :/
