The partition labeled "System" is where the System boot files which boot Win7 reside.
It is enabled by being the "Active" labeled partition.
The "Boot" label only means that is the OS which is booted at the time.
Remove the drive letter from System Reserved so nothing can write to it.
Remove the Active label from H so it cannot intefere: Partition - Mark as Inactive - Windows 7 Forums
Turn off the paging file for a reboot then set it to System Managed to see if performance improves.
If not work through these troubleshooting steps.
