I am running Windows 7 64-bit RTM and everything is working great. I am having no issues at all with it running. Reliability is at 10. Everything works (except my top gig of memory until the NVidia USB bug is fixed). I am getting the following errors in event viewer that ONLY occur on boots (not comming back from hibernate or sleep):A fatal hardware error has occurred.

HiAs I know, WHEA is intended to reduce mean-time-to-recovery for fatal hardware errors through richer error reporting and to reduce system crashes related to hardware errors through effective operating system hardware error recovery and health monitoring. It seems that it is caused by a badhardware (processor orRAM) or lack of compatible driver. If it is the case, it may cause system crash or other serious problems in the future. I recommend you to contact manuafacturer to obtain the updated driver. BTW, I found the following similar issues, it might be helpful.Event ID 18 (need help)Microsoft-Windows-WHEA-Logger; ID evento: 18Best RegardsDale
