Hi,
I own a 2008 Dell XPS 420 running Win 7 64 bit. I live in India, so there are frequent power cuts - the computer is connected to a APC backup so the computer hibernates automatically as soon as there is an outage. So there are no hard shutdowns.
Yesterday, the PC went to hibernate after an outage, and it won't boot after that.
Scanned the forums here for an answer for hours, but nothing has worked so far:
1) Tried to run in safe mode (tried all modes) - gets stuck at classpnp.sys and 'please wait.'
2) Tried 'Start-up' repair - after 'loading files', it goes to a black screen and nothing happens.
3) Tried 'Last known configuration', 'Debugging mode' and other listed options. Still nothing.
4) Saw some threads discussing switching SATA operation to IDE, but the Dells Bios does not have this option. Only Raid or Autodetect Raid/ATA, both of which I tried.
5) Reset Bios to factory settings.
6) Disconnected the power, removed the motherboard battery and put it back again. Did the same thing with HDD connector data and power pins.
7) Tried to Boot with original Windows installation DVD (after changing boot order in BIOS) and tried most of the options. When trying the Safe mode, the DVD gets stuck on disk.sys instead of classpnp.sys
8) Trying to boot with the DVD shows all the same symptoms as booting normally. I even tried to boot with a system repair disc I created during one of my back-ups. Nothing.
9) Removed all USB connections while doing this.
The funny thing is that I have a very recent back-up/disc image on the second HDD in the same computer - but the hard part is getting into the recovery options screen - which I can't.
Thanks for reading the long rant, and would appreciate any help!
