Before I get into the details of the issue I want to point out that this computer was running Windows 7 fine without any bsod or other errors for about 6 months. 6 months ago I performed a wipe/ restore of my system drive to clean out the crud that windows/programs build up over time. windows 7 had been running fine since I first installed in back in 2010 to replace xp. So yeah it was time to do a clean up. now on to the issue at hand.
I followed the guide how to enable sata from within win 7 without reinstalling the os. I'd never really tried sata to be honest, I'd just left it set at "Native IDE" in my bios when I did the upgrade from xp to 7. So I followed the guide and everything worked as promised. But my win experience rating didn't improve and I noticed no gains from doing it. The only thing that happened was my boot time increased a bit. So I decided to go back to "native IDE". I went into reg edit and changed the value back to what it was before, then on reboot I went into the bios and changed back to native ide.
Once I did that I got hit with the BSOD " bios not fully acpi compliant. see vender for updated bios"
Now this bios is updated, I had to do it a few years ago in order to enable support for am3 cpus on my am2/am2+ board. more to the point as I pointed out everything had been running smooth up to this point. So i figured no big deal I'll just do a image restore and be back up and running in no time. Man how wrong I was.
No matter what I tried, Macrium Reflect Winpe rescue or inserting the Windows 7 cd nothing worked. Maybe because both reflect's winpe and windows 7 share the same core code base. I don't know. Now Macrium's Linux based restore works fine but once I load my windows 7 backup image I still get hit with the bsod. I was able to install XP however, no bsod no nothing just a smooth install.
Things I've done to try to resolve this:
1. load optimized defaults in bios (failed to work)
2. used jumper to clear bios settings (failed to work)
3. safe mode (failed)
4. install win 7 via cd (failed)
5. Macrium Winpe rescue (failed)
6. install win 7 via usb key (failed)
7. Macrium linux recuse (50/50, failed on win 7 but worked on xp system image)
I don't know why xp installed without hiccups, maybe cause it's older, I'm just glad I didn't delete the old image from my backup drive. I'm stumped here. Guess I learnt my lesson, don't mess with it if it ain't broke. sorry for the long post but I wanted to give as much info as I could.
