Windows 7: Windows 7 reboots during startup - even in safe mode

Windows 7 reboots during startup - even in safe mode

Hi all,

I have a Windows 7 installation that I seem to be in an 'endless loop' on. First off, if I just let the system reboot, it comes to the windows 7 splash screen and then reboots again. This will happen endlessly if I let it.

If I hit F8 during boot up, I do get the Windows 7 menu. I have tried using the 'repair' options, but they don't succeed in solving the problem. I have tried going into Safe Mode and that also reboots after getting to the 'CLASSPNP.sys' driver (at least that's what it displays on the screen).

So I thought I would just 're-install' Win 7. I boot from my Win 7 DVD, and my options are 'upgrade' or 'clean install'. If I do 'upgrade', the DVD tells me that I need to start Windows first and then run Upgrade. Of course, I CANNOT do that since Windows 7 won't start! I'm afraid to do CLEAN INSTALL as I don't want to lose all the files on my system.

Please does anyone have some advice? This shouldn't be so difficult.

Oh, also, when I try to do System Restore from the repair menu it says I don't have any restore points (although I'm pretty sure I did).
