Upgrading from windows 7 to windows 10 error 0xc0000005

Ok, to start out with, im not going to lie, im slightly ashamed to be using the upgrade for disability services but at the same time I already had the free upgrade and will elaborate further in the text to come (excuse my punctuation, im dyslexic and punctuation is a sore point.)

I upgraded from windows 7 pro to windows 10 almost 2 years ago now when the upgrade was first made available free. Just day before yesterday I made some prety drastic upgrades to my computer. CPU, ram, MOBO, etc. Switched to the I7 7th gen from 5th gen, the list goes on. Windows immediately started acting up with BSODs and errors left and right. I figured maybe it was a licensing issue but that wasnt the problem. Checked my ram, CPU, Hard disk, nothing. I havent had a clean install of windows in a few years so I said F it and went ahead and attempted a reinstall of windows 10. After doing so I was BSODing on startup. I researched the problem and spent about 5 hours attempting to fix. I couldnt even get into safe mode. That said I popped the original windows 7 disk in and took it from there.

Windows 7 installed fine (but it took 3 tries before my SSD played nice with the install) it seemed everything worked. I grabbed the still available upgrade to windows 10 for disability services and attempted to upgrade after installing both before and after installing windows 7 updates but I am getting the same error each time saying could not complete upgrade, and the error code 0xc0000005.

Again I checked my new ram, my SSD, and adjusted my bios multiple times over and even reset my CMOS (some people say this has helped them) but nothing worked. I also tried going into CMD and checking the windows files and registry and everything seems in order. Ever since I made these upgrades with a 7700k and ddr4 ram ive been having problems. I dont think its the hardware tho because as I mentioned everything appears to be registering fine hardware wise.

Mostly I am trying to determine whether there is a fix in place that anyone could suggest that might help this upgrade move along or should I invest in a full win10 purchase, and if I do, do you suspect I will still run into problems. I called Microsoft support about this but it has been years since my last call and it seems now they have turned it into a paid service and I really have no desire to pay them for a problem that seems to be on their end as this seems OS related and not hardware related (though, I could be wrong.)

I truly appreciate your help and support,
Thornton Strolia

Just to address one point.. - that shouldn't be needed as you already have rights to Win 10 having had it installed.
That also means you should be able to clean install Win 10 again (no need to revert to Win 7 for that alone, or upgrade from Win 7).

I attempted this but was BSODing on startup everytime. Once I got this resolved I had a problem where I was getting an error message (cant recall which one but it resulted in a boot loop, not allowing me even into safe mode)

My main reason for attempting the version of windows 10 upgrade still available is only because I already had it and am hoping to avoid paying for it since I already had the legitimate upgrade. However, I will if necessary but am first hoping to get some advice regarding this error code. Obviously this is a problem I am having in windows 7. I would hate to purchase a (third copy for third computer) copy of windows 10 simply to run into more problems. I know nobody can insure anything but if it is a belief that with the problems I am having now, that they could persist even as problems have persisted now, rolling back to windows 7 as I have now, then I would like to move with caution before spending the money and would value the opinions given.

Have you got the W10 media on a USB, if so boot from the USB, pick clean install, delete the partition/drive you wish to install on (don't format leave unallocated) and off you go, if you have free upgrade, it remains with you, so you can activate at the end. If you have an old W10 media just down load the new media, it still works for free!

Oh ok, so similar to how you update your activation for windows after major hardware changes, I would just login after the clean install of windows 10 and it should update my licenses?

Do you believe this would have any impact on my problems? I mean, I passed the disk test, the ram test, my bios is all in order, so really theres nothing to go on hardware wise, but im still kinda curious. I mean, worst case scenario I doubt I would have any problems worse than the ones im already facing but of course, in a perfect world, which this most definitely isnt, everything is working as it should and im not having problems with errors around every turn.

Hi Thornton,

With all of the new components, have you actually got them up to date driver wise, that includes the Bios.
The exception code basically comes back as an access violation, but could easily refer to an incompatible driver.
The setupapi log should confirm .

And the really silly question are you dual booting, (grub/bcd)??

I ran the driver disk that came with the new mother board and am not dual booting on this machine. I have not checked if the bios is up to date but I can definitely try that to see if that makes a difference. I will post back when I have later tonight as I have not yet slept and it is almost 11am here but in the mean time if anyone else has any thoughts im interested in taking a listen (so to speak). Definitely curious because everything was working and even outside the case I cant pinpoint what the issue is. Initially I thought it was display drivers but even after running only the onboard dvi out and no drivers I stll had problems.

anyway, thank you all and I appreciate all the great help this forums members continue to provide!
