can't install anything/nsis error/corrupted files

[Deleted]

I started to get this error out of no where, I've did some research and it could have been the ethernet cable but I switched to wireless and the problem still persists. I don't have this error on my laptop so I know it can't be my net. I bought this desktop which was entirely built by scratch, and after I got it - I seem not be able to get any downloads done. I was able to download flash and chrome that came with it luckily installed, I tried to install firefox/chrome alone but no success (corrupt files). I have BSOD with 5-6 different things but I flashed the BIOS in order to reset the settings. (somehow my CPU was overclocked which probably caused the instability, not sure but I remember I had BSOD's of USB/Memory/SERVER etc. I then began to uninstall everything which surprisingly somehow fixed the issue?

Please help.

Thanks!

I didn't find the right solution from the Internet.
