Some of my games wont launch

[thefaq]

I have some games that will launch and some games that wont launch. I've tried File Integrity and Uninstalling and Reinstalling the games. In my library, when i will try to launch the game, it will show that its running, then it says syncing. That's it. Nothing else happens. I've tried to look up some help but everywhere i go it just tells me to do the file integrity check. Any help would be great full.

Games i have that does not work:

Rise of the Tomb Raider
The Witcher 3
Dead by Daylight
Ghost Recon Wildlands

Games i have that does work:
FF14
Middle Earth Shadow of war
Black Desert Online
Resident Evil 2 biohazard

Also games from other launchers work perfectly fine as well.

Is this a prebuilt computer ? What I mean is, did someone build it as in you or did you buy it new already put together ?

If prebuilt, they can often come with software that can cause issues with games and/or Steam.

That's covered in the link I provided above, but here is the support page found from there :

https://support.steampowered.com/kb_article.php?ref=9828-SFLZ-9289

From what you described above, and since your PC should be capable of playing those games, it sounds like a software issue running that will conflict with games/Steam, to me.

Make sure also any security software such as antivirus is totally ignoring Steam and games in real time scanning. Make exceptions in your antivirus for them, if you have not already.

[thefaq]

I built the computer myself. The games have worked in the past, it was just a couple of days ago that it stopped launching.

It still sounds like a software conflict to me, although I could be wrong. Even if you have not installed anything new recently. Sometimes, programs update and change and cause new conflicts.

If you wish, you can post some screenshots of your installed programs and processes and we can look to see if any might be an issue. That's up to you, but if you do it, do it as follows, please :

1. Take screenshots of all of the programs you have installed on your computer. "apps" (Windows 10 click "Start" (Windows icon on bottom left))

2. Click Windows Start and type in msconfig and run that resulting process. Go to the services tab and check the box on bottom "Hide all Microsoft services". Take screenshots of all that is left.

3. Then go to the startup tab on top of that same window (Task Manager in W10). Expand the header on the left so we can best see the process name (small window, so do the best you can). Take screenshots of all that there also. Don't forget to scroll down if needed and get everything in the shots, please.

Post all the links to the above screenshots here, using a file hosting site such as imgur.com, which is free to use.

The only time I've had that, was after I updated my Nvidia GPU driver and the newest driver was one which somehow didn't work with some games. Rolling back and waiting with updating til again a new driver came worked for me.

I can see that the GPU driver has the date from end of September. Any chances that got updated a short while before the issues came up?

Nice

I see a very high suspect :

Norton. Anything Norton or Symantec is very notorious for being overprotective. Those background processes can possibly be causing issues with the games running.

Daemon Tools Shell Extension. Another known conflict possibly, with Steam and games, as seen in the past.

My bet is it is Norton.

You have a LOT of background processes running. I would suggest you investigate and research what they are and consider disabling ones not needed for gaming. Those are just taking up resources needlessly when you game. You don't need some of those for gaming anyway.

EDIT...

After resolving any conflicts, you need to verify the game files before trying to play the games :

There are a few other possibilities also :

Nahimic , Advanced System Care (IOBit). Honestly, there are two ways to go about this.

short - erase system disk and make clean setup, or, uninstall all the bloatware/conflicting software, and try restore default system settings and system files, then try to fine tune the system, but that's probably going to be long and painful.

There is just so much you have installed on it that can be an issue with gaming.

[Crazy Tiger]

112 background processes? WTF?

You might want to check what gets started on start-up. Often programs run services on start-up that are unnecessary, in many occassions it's enough to just start the program when you need it. For example, I don't let Steam start on start-up. Same can be done with Origin.

I'm also tempted to say something went wrong with the Nvidia updates. I find that too much Nvidia processes, any chance an old driver didn't get properly uninstalled?

I agree with TGO, Norton can be a nasty one in that regard.

[thefaq]

So i tried almost everything you guys suggested, uninstalled a whole bunch of stuff including Norton and Daemon Tools. I just haven't tried wiping the disk yet.

[thefaq]

I should also mention when i go to the local file and launch the games from there i get a dbgcore.dll not found.

[thefaq]

okay i got a fix for now. I just copied the dbgcore.dll from a game file that i know to work, and put in the game file i know to not work. So far it is working.
