Read the sticky already. None of those solutions are applicable. it is getting into windows boot screen. The memory is from another computer that was running very well for a long time, so it's not likely the problem. I cleared the BIOS already and also re-installed the OS several times. No help thus far.
Got the OS installed. Setup complete. Starts to boot like normal, then when windows gets to the splash screen (first screen with windows logo, says 'windows starting' or whatever), then restarts before getting to the desktop.
I shut down for the night after installing what I could in safe mode. Will continue tomorrow evening.
