Apparently this problem has been around for a while. According to this Microsoft forum thread, many times it can be the result of an older program or application sending a command to unhide the task bar so an application or program update (or some other message) can be viewed.
Taskbar does not Auto-hide all the time Windows 7 - Microsoft Community
I'd start out by looking for application conflicts. Run a clean startup (AKA clean boot) and see if the problem goes away.
Troubleshoot Application Conflicts by Performing a Clean Startup
If that doesn't help you could try looking for damaged or corrupt system files by running a system file checker scan from an elevated command prompt (option two.) If problems are found, run the scan 3 times and reboot the computer after each scan.
SFC /SCANNOW Command - System File Checker
Personally, I think the best solution is to remove all the HP bloatware from your computer. You could do a clean reinstall (my recommendation) or try to clean up just the factory bloatware which many times prevents Windows 7 from working as it should (not quite as good as the clean reinstall.)
