Windows 7 boot crash - even in safe command prompt mode - even after repair

My Windows 7 (x64) installation keeps crashing on me and I need to figure out why.


Here's what I've done so far:
- Problem occured after setting an (obviously) too big step in the CPU base frequency (BCLK) to a lower setting. At that point my Windows BSOD'd and did never boot again so far.



  • Crash occurs always at the same point: After the first red dot of the Windows-Logo appears on the screen. BSOD flashes for an instant, the computer then immediately goes into the reboot sequence.


  • Safe Mode looks exactly the same


  • Safe Mode with command prompt shows a list of drivers scrolling by then BSOD's in the same way.


  • Last known good didn't help


  • I had recently set up a windows repair disk for my system, but although the "repair" option seemed to do something, it didn't help.


  • chkdsk shows OK, no errors found.


  • At this point I had to rule out a hardware problem, so I installed Win 7 again on an empty partition (same disk). Starting that installation, everything works fine. I can run any hardware test I want, play games, etc. - no problems.


  • I tried startup log on the bad installation but there is no nt*.log/txt file in the bad installations \windows folder.



Does anyone know where I can find the sequence of drivers Win 7 loads at boot? I can get a glimpse on the last driver loaded at the safe mode cmd-line startup but I need to know what's next.


Any other ideas?
