If IMVU is crashing every 10 minutes due to running out of memory, even with only one website open, you can follow these steps to troubleshoot and potentially resolve the issue.

1. Check System Requirements
Ensure your computer meets the minimum system requirements for running IMVU. An insufficient RAM capacity can lead to performance issues.

2. Clear Cache and Temporary Files
Accumulated cache and temporary files can consume significant memory.

- Press Windows + R to open the Run dialog.
- Type cleanmgr and press Enter.
- Select the drive where Windows is installed (usually C:).
- Check the boxes for "Temporary files" and "Thumbnails," then click OK to delete.

3. Uninstall and Reinstall IMVU
Sometimes, a fresh installation can resolve persistent crashing issues. Make sure you back up any important data before proceeding.

- Uninstall IMVU through Control Panel.
- After uninstalling, manually delete any remaining folders in C:\Users\[YourUsername]\AppData\Roaming\IMVU and C:\Users\[YourUsername]\AppData\Roaming\IMVUClient.
- Reinstall IMVU from the official website.

4. Limit RAM Usage
IMVU has a strict 3.5GB RAM limit for its Classic Client. If your usage exceeds this, it may crash. Monitor your RAM usage using Task Manager.

- Open Task Manager by pressing Ctrl + Shift + Esc.
- Click on the "Performance" tab and inspect the Memory section for usage.
- Consider closing other applications if RAM usage is high.

5. Use Low Memory Bypass Tool
A Low Memory Bypass Tool may help if you're consistently hitting memory limits within IMVU.

6. Adjust Graphics Settings
Simplifying graphics settings in IMVU can reduce memory usage.

- Launch IMVU and go to Settings.
- Under Graphics settings, lower the quality settings to see if it stabilizes performance.

7. Operating System Updates
Ensure your Windows operating system is up-to-date, as updates can include performance enhancements and bug fixes.

- Go to Settings > Update & Security > Windows Update.
- Click on "Check for updates" and install any available updates.

8. Check for Background Processes
Some background applications may consume excessive system resources.

- In Task Manager, review the list under the "Processes" tab.
- End any unnecessary processes that are consuming high resources.

9. Analyze Compatibility Settings
Ensure that IMVU is compatible with your operating system.

- Right-click on the IMVU desktop shortcut, select "Properties," then go to the "Compatibility" tab.
- Run the compatibility troubleshooter or adjust settings to compatibility mode for an earlier version of Windows.

10. Seek Support
If none of the above steps work, consider seeking help from IMVU support or community forums. You can check out the discussions about crashing on Reddit and other IMVU community sites for additional advice logged by other users who faced similar issues here - [learn more].
