All downloads corrupted...

Got a bit of an odd issue here, was handed a friends pc that had started BSOD'ing, they'd attempted to fix it and tried (and failed) to re-install windows, machine came to me with the gfx card secured to the next slot over so it was twisted badly, ram was only half in and the wrong way around, gave it a good check over, put everything back in it's correct place, booted up and installed windows 10 happily, then the issues start.

It will happily browse the internet, youtube works fine, it'll even play games if I can get them installed, etc etc... however anything I attempt to download such as malwarebytes or windows updates tend to fail with a connection interrupted error or the download is corrupted, files transferred via LAN appear to suffer the same issues as well.

I disabled the onboard LAN adapter and put a pcie wifi adaptor in which appeared to work, swapped it out for a pcie LAN (same slot as the wifi adapter was working in) and it starts having the same issues. If I hit retry often enough it will eventually manage to download something. Power management on the LAN is turned off.

Anybody have any ideas of what could be causing the issue and any fixes to try?

Windows 10 and 7 have been tried, both fresh installs with the same results, hard drive tests good as does memory. System is:

AMD FX-4100, Gigabyte GA-78LMT-S2P, 4GB DDR3 and a 240GB Drive.

Ok, appears to be the gfx card causing the issue... odd as it seems to work fine otherwise and was quite happy to run Elite when the wifi card was in the machine.
 
To me it sounds like something is not right with your lan hardware.

I would try installing a PCI-E Ethernet card.

I did, it's in my first post. As stated above, the gfx card appears to have been at fault, having removed it and swapped to the onboard gfx output everything appears to be working just fine.
 
Never seen a GPU cause that - usually large file downloads being corrupt is due to either the storage, system memory or memory/chipset controller being unstable - even the LAN hardware is less likely to be the cause than those 3.
 
Nor have, it's exceedingly weird, my money was on memory or hard drive being at fault but the gfx card wasn't even on my list.
 
Just re-read your post - could still be a memory issue as swapping to the onboard video and removing the GPU will have changed how the system memory is being used - possibly a critical area is now no longer being mapped to a failing location, etc.

I've had systems pass quite long memtest86+ runs but still BSOD with memory controller related codes (0x9C, 0x109, 0x124, etc.) and cause corruption and crashing.
 
That is true, but it's still odd that the only thing affected appears to be downloaded or transferred files, in my experience faulty memory usually manifests in more than a single specific manner, obviously I will be giving it a thorough testing to try and ascertain if the memory is at fault.
