How far along into the Windows load does it go? Does it get past the BIOS then reboot immediately, do you see any "WINDOWS" loading first? Have you tried to hit F8 right after the BIOS, and attempt to boot into SAFE mode?
You say you tested you ram, how? Did you try to boot with a single stick of ram, actually, trying to boot with each stick in turn?
Did it work before, with another brand/amt of memory, and it's failing now with a ram upgrade?
Did you just install Windows, and if so, did it seem to complete the install ok? Can you boot from a Windows install disk?
You also mention you have to hit F1, that sounds like it's not set to boot from the drive Windows is installed on. So, how many drives do you have, and are any in a RAID? I would check in the BIOS, for the proper drive boot order, and to make sure on the SATA screen, that RAID is set, if your drives are in a RAID. Some of these Asus BIOSs forget their settings, mine did all the time, and I would have to go in and set it to boot from the MSATA (I have Win 7 loaded on my MSATA) as it would forget and try to boot from my RAID.
