Win XP & h/d lite flashing

[cccapt]

OK, I tried FileMonitor and there is a lot of activity going on, but I don't really know what it all is.
Maybe someone can tell me if they know what this all means.

While my system is sitting idle, here is what I see..........

10:42:47 AM explorer.exe:1692 IRP_MJ_CREATE C:\ SUCCESS Attributes: Any Options: Open Directory
10:42:47 AM explorer.exe:1692 IRP_MJ_QUERY_VOLUME_INFORMATION C:\ SUCCESS FileFsQuotaSetInformation
10:42:47 AM explorer.exe:1692 IRP_MJ_CLEANUP C:\ SUCCESS
