go to bios and disable plug and play os
assgin irq to pci disable
This is more likely a driver conflict. Since safe mode works then this most likely means that there is a driver that is not playing nice that isnt loaded with safe mode.
In safe mode uninstall a driver then reboot see if it goes into windows normally. If not reboot in safemode, remove another driver...rinse and repeat.
May take awhile but you should be able to fix your computer and determine what the root driver problem was.
OH I forgot to add: Please do disable plug and play OS like gomerpile stated.
