I have problems that "Cache Hierarchy error" floods event viewer every 2min. Everything seems to work ok, no bsods or crashes but alot warnings on event viewer. I have tested system memories and used several Diagnostic Tools outside windows to test like PC-CHECK. All of them says my hardware works. I have tried also download latest drivers, intel chipset, realtek hd.
