Windows 7 BSOD after HDD move.

Ok, I'll make this as detailed as possible.
Background
I had an HP laptop that I upgraded to Windows 7 as soon as I got my discs in the mail. The laptop is as of now 14 months old (and was purchased refurbished) and last week I went to restart after it froze when I was trying to bridge two network connections and it wouldn't get past the HP screen (can't even access the bios) I'm figuring it eventually just over-heated and I probably fried somethin.
Issue
So a friend of mine gave me a Gateway he has that has a broken screen. Naturally the first thing I tried was swapping the HDDs. Of course, said actions did not work and I was given a Blue Screen (0x0000007B, 0x80786b58, 0x00000034, 0x00000000, 0x00000000) so I hit up google, it seems to be a motherboard controller issue. I have tried the startup repair, it will not fix it. System Restore obviously will not work as the old laptop was 14 months old (and yes I had tried). I have tried a Windows 7 Live Disc also, that just gave me a 0x000000c7 error, no big deal I didn't think it would boot anyway, just thought I'd try... So now I am at a stand still and have signed up on these forums because I am desperate for help! I really need to not lose my documents from that HDD; I'd lose almost a year of school work (including some projects that are due very soon!) I can't think of a way to do an upgrade/repair install thanks to the blue screen... A thought crossed my mind, if I boot into a linux distro via a thumdrive (in particularly Backtrack 3) is there some way I can delete the old motherboard drivers manually? (as in delete specific .ini files or even .dll files) I am open to any suggestions...
Afterthoughts
This is the biggest HDD in the house (and the files I have to keep from losing are bigger than the other HDDs in the house) so even if I got my hands on an external casing I don't exactly have anywhere to move em to, but if I could move em somehow within the HDD so that I can just move em back after the reinstall of Windows 7...

Welcome!

When I think about it, I believe you are going down the wrong trail. The hard drive seems fine, demonstrated by the fact that the other HD did not work, and supported by the error messages pointing to a bad motherboard.

Even if you can backup the data, what will you do next? Choose what makes sense for you, but you could take the machine into the shop and get the motherboard replaced, buy a new laptop, or find an identical machine and replace the MB yourself.

Either way, you can hang onto the hard drive, and not worry about the data on it.

Hope this helps,

P.S. Can I recommend a high-capacity external hard drive for backup space? It is a scary position to be in when you have more data than you can backup.

It seems you misunderstand, I am trying to recover the one from the HP by either deleting the drivers by hand somehow (incredibly lost on how to pull it off without being able to boot into it) or moving the data to a location on that same hardrive that won't be affected by me reinstalling 7. I am aware the hard drive is fine, it's the windows 7 installation that needs repair because I must put that hard drive into this gateway. (causing the motherboard conflict)
So I need to reinstall (or somehow repair) windows 7 without losing the documents.

If you can boot into the Installation Disc, go ahead and install right on top of your current installation. Be very careful not to format the drive, because if you do, you will lose all your data.

Your files will be backed up to a folder called Windows.old, and placed in C:.

If we have the Dump we can nail the issue more specific https://www.sevenforums.com/crash-loc...d-problem.html

You could perform a Repair install I'm not not wrong

Sorry forgot about that
