Windows 7 won't boot, repair and restore won't work.

[Wyld36]

Hi, last night my power chord was halfway out and made my computer flick on and off a few times before I plugged it in completely to restart my computer. It ran fine, I turned it off. The problem started when I started it up again.

As the windows logo was flying together as it boots up it pauses for a second then flashes into the blue screen and then straight into a windows repair screen.

I tried to auto repair and system restore and it won't do either.

I have tried to unplugged my HHD
removed all RAM one by one
Removed battery from motherboard and reinserted

Nothing has worked

If you need any more info please let me know
Any help would be great! Thanks

Wyld

It can take 3 full cycles from the Windows install / repair disk to restore a bootable OS. Try that first.

Did "system restore" run succesfully? But actually didn't fix the problem?

Boot to http://www.sevenforums.com/tutorials/666-advanced-boot-options.html and select "Disable Automatic Restart on System Failure". The next crash won't restart the system automagically. What's on the BSOD?

Hi guys, thanks for quick response!

I tried disabling the auto restart and it just took me to the screen with the option to try and do an auto repair or start in normal mode.

I managed to find a solution here BSOD after during windows logo on boot [Solved] - Asus - Motherboards

Except I changed my SATA config from IDE to AHCI not the other way around. I have no idea what this means and whether I might need to change it back. never the less I quickly made a bootable cd of my windows and backed up all my drivers! I am considering doing a clean boot of Windows. I haven't formatted once in over 3 years.

Everything seems to be working ok for now. I restarted my computer a few times and keeps restarting alright.

I don't understand why I would need to change this setting after over 3 years of having my computer though? Would the power cable being half way connected someone how changed a BIOS setting?

Cheers.

Did you change BIOS SATA config from IDE to AHCI. After that the BSOD problems began? Please explain.

I didn't do anything, it just would not boot all of the sudden and I got this error. The only thing I can recall which was out of it's normal use was that I nudged the power cord with my foot and it spasmed on and off a few times until I plugged the chord in properly.

It rebooted fine and then the next day is when I got the error. I went into my BIOS settings and changed the SATA config from IDE to AHCI which fixed the startup problem.

Like I said I have no idea what this means I just found it on a forum and it worked.

I would like to prevent this from happening again or just understanding why this could happen.

There is a tutorial on changing to AHCI from a windows install - its requires some registry entries. Typically you need to install windows after switching the mobo to AHCI (and this is likely the cause of your BSOD) but it can be fixed from the OS. Don't have time to find it for you but its here and you can Google for it.
