[Intel HD Graphics 620]-"Device not started (igfx)" - that's what it said on the driver's events properties

Indeed the tutorial could have caused a problem as things are complicated today and people making tutorials don't always see all the consequences. However, if the driver is for the 620 and you have a 620 then it should have been fine that way. You shouldn't have to uninstall the current driver and you can install a driver from Intel's website if they offer a directly compatible one - these two things shouldn't cause a failure in of themselves though a clean or "clean" install is always recommended. If the tutorial had you do something weird or strange like edit the registry or copy other files or something then things could be messed up.

I see DDU has Intel listed but don't know the extent it can clean the Intel driver so it might be another way. With Nvidia there's zero reason to use DDU as the Nvidia driver has a clean install option during updates and I've used that setting to 100% no driver issues (been using that setting for most of Windows 10's existence). So if Intel has one somewhere in the update installer then it should be all you need.

I don't think you have a hardware failure unless the driver is a coincidence and it was failing before it without you noticing. Possible but less likely.

Hi Sean,
My name is Igor, I have 12 Microsoft MVP awards. It's a pleasure for me to help others and I'll do all my best to help you. I'm sorry you have a problems.

Please reinstall graphic drivers from PC/motherboard support site.
Repair system files by
DISM.exe /Online /Cleanup-Image /RestoreHealth
command from Windows PowerShell (administrator) environment.

And unfortunately this may mean hardware problems too. Did you re-insert CPU or changed thermo interface recently?

No, I did not do any changes or re-inserting, anything CPU or thermo related.

Speaking of reinstalling graphic drivers, I just recently installed a graphics driver installer (exe) that was from my laptop's site (Dell). But it's not the same as the Intel Graphics driver I currently have. It's Intel, but not intel 620 like I previously mentioned ....it doesn't have numbers in it. I did not yet install this to my device, I just installed the graphics driver installer. Look at this:

Questions:

If I install this driver(that driver shown in the picture), assuming that this will fix the problem, will it be a downgrade?? And WILL IT FIX the problem?

And by the way, can I ask if what do you mean by DISM.exe? Is that an application/software that I need to install or do I just type that on my Windows PowerShell(Administrator)???

Thank you! I appreciate your response.

But no, I did not do anything weird or strange like edit the registry or copy other files or something. The tutorial I chose to watch was a 2-option fix, the first one was too hassle and it involved editing registry or something, copying texts, so I skipped the first and I did the second fix which was installing a similar graphics driver in the intel download center, believing it will work.

Buuutt..... it did not fix the "intel graphics settings missing" issue on the context menu at all. It only made my PC worse :((. So I performed a system restore but it did not work. It was still laggy when I'm playing. It was never lag before.

I did the Dism.exe thing......it didn't work:(((

PLEASE I NEED A SOLUTION FOR THIS

Should I try the graphics driver from my manufacturer's website instead?

OK so I tried the manufacturer's graphics driver. So it turns out its the same driver....Intel HD Graphics 620. I restarted my PC, then I went back to Device Manager>Display Adapters>Intel HD Graphics 620>Properties>Events....to see if it worked. Well it didn't say "Device not started(igfx)". It said something else...look at this:

Information:

Driver Management has concluded the process to add Service igfxCUIService2.0.0.0 for Device Instance ID PCI\VEN_8086&DEV_5921&SUBSYS_078B1028&REV_06\3&11583659&0&10 with the following status: 0.

So I checked to see if I can play my game smoothly now. Well, it turned out to be still laggy, but not laggy as before though. So then I tried to find any updates for this new driver, in attempt to fully fix my gameplay, and when I did and when I installed the update, the problem/error went back....It said "Device not started(igfx)" again. It turns out that when I update the driver, the device won't start. Remember this was the driver in my manufacturer's website.

Oh and by the way, here's a command window with DISM command and its results:

OK so I run Dxdiag and I copied the information about my display devices and found this:
