I installed Windows 7 RC, everything was OK for a few days. This morning I turned it on and it can't boot up properly. WerFault.exe, runonce.exe, explorer.exe, and misexec.exe all fail to load. 0x77243892 error, says the memory could not be read. Only thing that shows up is a black screen with the Windows 7 Evaluation copy. Build 7100 on the bottom right hand corner. I went into safemode and did a system restore on its recommended restore point, but it's doing the same thing once Windows 7 tries to load. Any ideas?
