Media Browser dies and needs to be restarted by logging off

Sometimes Media Browser won't load at all from WMC.

1. Sometimes it just refreshes and that's it.
2. Sometimes it will start to load but the screen will stay blank for a few minutes before displaying an error message that Media Browser won't load.

Sometimes = every few days.

I'm running Windows 7 with external RAID. Not much else on the box.

Has anyone else had similar issues?

Thanks for responding.

My boot drive is a dedicated 2.5" drive with nothing but software and the MB image files.

I'm running RAID 5 and it looks like a single 6T volume mapped as a drive letter. When it stops working I don't see the R/W LEDs working so it doesn't appear to be accessing the RAID.

The boot is a regular hard drive.

The RAID is attached to the HTPC. It's just external. However, I could change the path from the drive letter to the fully qualified name.
