After booting, the computer freezes at the welcome screen after logging in as any of the users. Sometimes it will restart automatically, other times it has to be "hard shut down". It freezes at the same time, consistently.
Occasionally, through an unknown set of steps, I can get the computer to boot properly. It crashes after a short while of using it, and then once again crashes at the welcome screen. Every time it has crashed so far it was while playing a game (not necessarily graphics-intensive). Again, after this crash the computer returns to just crashing at the Welcome Screen.
Booting to safe mode works every time.
Malware Scan with Malware Bytes (clean)
Memory test with Windows Memory Diagnostic (clean)
Ran Driver Detective (said I needed an update on my Video, Audio and Network Drivers)
Various System Restore and Last Known Good Configuration (occasionally works for a short while, but then computer freezes during use and problems return)
Clean Boot (does not work, still hangs at login)
Disabled network card, sound card, and display adapter through device manager (does not work, still hangs at login)
Reinstalled latest version of Video and Audio Drivers (no change in behavior)
Reinstalled Windows 7 completely (computer seemed to work fine for a while, then had same problem)

About 2 weeks ago, I had another problem where the computer would randomly freeze during use, after login. To fix it, I installed new Display Drivers for my video card. The problem disappeared and the PC has been running fine until now.
I'm at a bit of a loss now about what to do. The next step for me is to try taking out all but one stick of ram and seeing if there is still a problem. If it were a RAM problem, it just seems so unlikely that the problem would be as consistent as it is. I would also think I would occasionally get problems in Safe Mode.
I also may reinstall Windows 7 again and be more careful about which updates/drivers I install. After the reinstall I started doing Windows Updates, which might have caused me problems. I may also install Windows on my Data Drive and see if that makes a difference.
Any thoughts or suggestions are helpful. Thanks for your time!
