When submitting a ticket, there are a couple things that can be included that will help our developers in identifying and fixing an issue. Also, this may save some time in waiting for messages back and forth between you and the support staff.
1. Open the Warframe Launcher,
2. Click the little gear in the upper right corner
3. Click the Get Logs button
4. Let the process complete and look for a Warframe Logs folder on your desktop
5. Drag the "Warframe Logs" folder onto the 'attach file' field of your support ticket
Once uploaded you should see 3 files listed: 
Screenshots: If you see a crazy visual issue, a screenshot can really help us understand what you're seeing.
You can capture a screenshot by pressing F6 in game. The screenshots will then appear in your Pictures folder in your User account folder.
Default directory is: C:\Users\YourWindowsAccountNameHere\Pictures\Warframe or simply %USERPROFILE%\Pictures\Warframe
Win XP users can find them at the following location: C:\Documents and Settings\YourWindowsAccountName\My Documents\My Pictures\Warframe or %USERPROFILE%\My Documents\My Pictures\Warframe
Or if you are using Steam, you can use Steam's screenshot functionality by pressing F12 in the game. The screenshots will then appear in the screenshots section of the Warframe entry in the game library.
WAR-# number: If or when you experience your crash of Warframe, you should see an error window popped up mentioning the Evolution Engine crashing. Please complete the process and enter any details about what you were doing at the time of the crash. Once completed the crash reporting tool will give you an error number that will look like WAR-123456 With that we can start to narrow down your problem.
