Steam crashes on startup and only will start in safe mode

[Satori]

Hi, so about two weeks ago when I tried to start up steam like I normally do it just crashed on startup, it would say connecting to account and then immediately crash. I looked in task manager and it would start up but then after a few seconds would disappear and then steam error reporter would show up and then quickly disappear as well leaving me with nothing.

I tried following all the fixes from this post (https://steamcommunity.com/discussions/forum/1/2217311444331264495/) because it seems pretty similar to my issue but even after doing everything suggested in that post along with a bunch of other things the only way I can get steam to start is if I'm in safe mode with networking, then it works fine. What I think is happening is that a specific program is blocking steam from opening but even after running multiple cleaner programs like adwcleaner and ccleaner it still refuses to work.

If anybody knows any fixes I would be glad to try them out!

(Here is also a list of all my programs [Link Removed] )

(Hopefully those two links work)

Msconfig , start debug what cause this.

ps.
besure steam.exe is on exception rule in firewall and antivirus app. might need reboot after added them, well aient that depend on what Brand name securiy you have or how they made it.

and check your own links , nothing works.

I've tried disabling antivirus and I think you mean reinstalling windows? which I would hope to be a last resort

First of, there're some apps on your computer that raise the question: Are you sure you downloaded them from trusted sites, and not from spoofs or other mallicious sources?

Various connectivity apps: they are all needed for MP-games right?
Except perhaps JDownloader, needed for work, school or semi-professional design?
- And what about qBittorrent?

What do you need Java for? If not for specific purpose, we don't need that on our computers anymore. Browsers take care for that.

Permissions should also be set in your firewall (Windows Defender i presume?) and in SpyHunter. These permissions should be automaticly added when re-installing Steam anew, which can also help resolve other types of Steam crashes.

Now keep in mind that re-installing can be done more simple then "advised in most cases". However the "advice in most cases" is mostly incomplete. For simple and more elaborate methodes it's important to first remove old launcher (steam.exe) and shortcuts there-of (desktop taskbar and start menu icons), then download a new installation file from the Steam website and run that. Do NOT use the old steam.exe as per the "advice in most cases".
When largely already installed, the latest installer version will re-add missing or damaged files and permissions, including what's mentioned below (where the old launcher or shortcuts there-of can not always do that).

Files can be missing or damaged by impropper use of the cleaning software like CCleaner you ran, if you included a registry cleaning with that. Antimalware and Antivirus may also have such a registry cleaner. Iobit has one too. Just don't use the registry cleaners. That's a job for professionals who actually either have more sophisticated software for such tasks or don't need such scanners at all. Impropper use of registry cleaners can be harmfull to the registry.

I dont think I have any viruses but I could be wrong ive ran multiple different virus scanning softwares and with avast I did an entire scan of my computer. JDownloader I use sometimes for specific files and then qBittorent I really only used to download this game called Enlisted because I couldn't get the regular install to work

Also steam wasn't working even before I used ccleaner

Then finally do you want me to try downloading a entirely different steam.exe and then replacing the old one? cus I haven't tried that

[Satori]

Hmm, steam support finally got back to me and said it was this file "nvd3dum.dll" that was causing the crash any idea what it is or how to fix it?

[Satori]

Ok, so I ran a 'sfc /scannow' command to fix the dll and after a reboot steam finally works! thanks everyone for your help!

[Iceira]

thats Nvidia issue with "nvd3dum.dll"

re-inatll GPU DRIVER with custom install , and make clean install, then checkbox is there.

and to be sure its not a nvidia issue with core driver from nvidia. and that why you re do this.
