Win 7 Error Loading OS after swapping cases

[Imp]

I just swapped my entire system from an Antec SLK1650 to a P183, and got an 'Error Loading Operating System' prompt, and it went into a safe/repair mode, but said it couldn't repair the problem. It loaded properly and everything is working fine so far.

Now, every piece of hardware, aside from the case is the same as I had since the last time I booted Windows 7. Possibly with the exception of the hard drive SATA connector being moved to a different port on the mobo. Otherwise, I damaged something in the move, but the fact that I'm typing this from the system in question suggests otherwise.

Is this something I should be worried about? Namely, did I damage something, and this is causing Windows to act up?

Also, we're renovating the house right now, so I had the system unplugged since last Sunday, and the PSU was disconnected for a few hours (CMOS battery is fine).


Thanks.

If you moved the connector to another port then you changed the hardware address for where the system expected the boot info to be . If it is fine now then windows corrected the error.

That makes sense. I think I moved it from the SATA-1 to SATA-0, which would explain it. Didn't think it would be a problem since I did it all the time with my old motherboard on XP, and the OS never complained. Then again, the SATA controllers on that board turned out to be defective.


I'll be upgrading the video card from an Nvidia to an ATI either today or next weekend, so should I reinstall everything just to be safe? Otherwise, I was just going to run a drive-cleaner in safe mode.

No need to re-install for a video card. If you want to be extra careful, remove the drivers for your current video card, power down, install new card and go from there.

I was only going to consider reinstalling Windows due to the aforementioned error and the video card together.

After scanning all the drives for errors, and Windows running perfectly fine, looks like it's fine. Worst case scenario, it starts crashing a lot and I reformat.

Thanks for everyone's help.
