Thank you for your reply.
I tried...
windows update = up-to-date
Graphics Driver = up-to-date
Sound Driver = up-to-date
Windows safe mode (no non-microsoft service, no startup app, no graphics driver(ms driver)) = Not OK
no sound driver = Not OK
try various directory settings and registry settings = Not OK
Re-install Rapture & Z3ta+2 & CCC = Not OK
32bit VST, 64bit VST, VST2, VST3 = Not OK
All VST HOSTs (VSTHost(freeware),Ableton Live, Cubase Pro8.5, Cubase Pro8, Cubase7.5...etc) = Not OK
Rapture Pro2.0.3, Rapture Pro 2.0.2, Z3ta+2 v2.2.1 = Not OK
Z3ta+2 2.1 = OK
Run as system administrator = Not OK
Change security settings of folders = Not OK
Windows compatibility mode (Win8, Win7, Vista) = Not OK
No windows GUI scaling = Not OK
No ClearType = Not OK
Change display resolution = Not OK
Change sound device = Not OK
Install to SSD, HDD = Not OK
Rapture Pro log file = no problem
windows system log = no problem
I'm worried about one month to this problem...
I have more than 50 plug-ins, all plug-ins are OK.
I think this problem is due to compatibility with specific hardware or chipset...
