content: The details of the BSOD could be useful. (Do they indicate a HDD failure?)Considering the battery was gone the BIOS settings seem a good starting point.

content: This is the bios screen setup, not a windows BSOD does it start in this windowsAnd your drive should be primary master to help a little bit, sure you can choose it in the bios settings, a dead battery would mean failed bios setups and the clocks settings gone.It can change the boot device(s) order and other things like serial parallel usb etc ...Normaly you should have a ''default bios setting'' selection in the bios, sometimes it help settings things or correct a few things for a startup

content: If windows is blue screening at startup and coupled with a dead flat bios battery I suspect low lever hard drive drivers are at fault. If the hard drive controller settings were lost then it might be trying to use the wrong ones. ATA VS AHCI VS RAID (this needs to match what windows was INSTALLED with). Check the hard disk controller type first. The good news here is it will make windows think it is broken but it is not. Also don't let windows try and repair its self this really did not start working well until about windows vista. But the battery being totally flat will cause a BIOS reset to factory defaults.The good news here is should be totally recoverable. Bad news is you need an IT guy this time. I expect some BIOS settings are preventing the boot. I don't think anything is broken. At least not yet. hard drive faults are always a possibility.
