For those who have problems with VAC (PC blocks VAC) (1 Viewer)

[Wasman]

An issue with your computer is blocking the VAC system. You cannot play on secure servers.

How do I fix this?

Enable DEP

Data Execution Prevention (DEP) must be enabled to play on VAC secured servers. To restore DEP settings to default please follow the steps below:

• Exit Steam.
• Click the Start button, then 'All Programs', and 'Accessories'
• Right-click on Command Prompt and click "Run as administrator..."
  - Please note if you are running Windows 8 you will need to press Windows Key + X and select Command Prompt (Admin)
• In the command prompt, type the following command and press Enter:
  bcdedit.exe /deletevalue nx
• Restart your computer.
• Launch Steam and test the issue again.

Restart your computer

If this is a problem for you on all servers then you can try fixing this problem by exiting Steam and restarting your computer.

Repair the Steam Service

This may also indicate a Steam Service failure. Please try repairing the Steam Service:

• Exit Steam.
• Click Start > Run (Windows Key + R)
• Type the following command:
  
  "C:\Program Files (x86)\Steam\bin\SteamService.exe" /repair
  
  (If you have installed Steam to another path, please replace C:\Program Files (x86)\Steam with the correct path.)
  
  This command requires administrator privileges and may take a few minutes.
• Launch Steam and test the issue again.

Conflicting Software

This issue can be caused by third party software interfering with your game or Steam. Please restart your computer, then launch Steam and the game without running any other third party software.

how hard is it to read this? Everything you wrote here is stated in this help article.

 

[Wasman]

Yeah but sometimes ppl don't know for what they search.. So i wrote it down here..
And maybe some people are lazy to type i don't know ..

 

[Da Random]

So you are telling me, that the game doesn't send you to the page when this happens? okay then.

 

[Wasman]

Mhm they don't.. Well not for me..

 

[Da Random]

In CS:GO they do, otherwise it just prints a link you can click on and you will be re-directed to the page on the steam browser AFAIK.
Otherwise, if one knows how to use google then it should not be difficult.

I understand that you want to try and help, but I don't think it's a problem that will not be left unsolved because people use common sense.

Yeh ok but still iam not playing CS:GO in tf2 they don't give you this..
And btw why you commenting this
(don't understand me wrong) ...
This thread is just here to look and find some answers ..

I've done many of the things listed in that article and it still hasn't stopped. I can access Jailbreak but not FF2 for some reason, if it restricts any further then I'll just get pissed off even more... I've also re-installed TF2 which was a pain in my arse.

Sorry this are the only things that "can" help they must not...
