Vista Tutorial - Vista Home Premium 64bit Stuck at Microsoft Corp. Load bar

My computer was working last night and this morning when I went to turn it on, it got stuck at the black screen with the Microsoft Corp load bar. It goes across and across but nother ever happens. I ran registry cleaners and whatnot, and nothing. I did some more looking and it looks like I've lost some system files somehow. It will boot in safe mode. SFC.exe says that there's nothing wrong when I ran it in safe mode.

Edit: I ran the Event Viewer in Safe mode and found this:

The following boot-start or system-start driver(s) failed to load:
eeCtrl
SASDIFSV
SASKUTIL
spldr
SRTSP
SRTSPX
SYMTDI
Wanarpv6

boot to last known good config. Worked for me on alot of occasions. Hope this helps. Instuctions is at safe mode prompt choose last known good config instead..

Disconnect all peripherals. All you want connected is the main hard drive, display, mouse and keyboard. No thumb drives, external drives, nada, zilch. Then attempt a boot.
