Cannot update or download anything (Windows 8.1)

My Acer laptop running Windows 8.1 will not download any files, will not update using windows update, majority of flash does not work online either.


When trying to download files:
On IE - they will download most of the way through, then say download interrupted, then I can resume the download but it either ends up failing, or when the download is complete the program will not run or open or anything.
On Firefox- Files will not finish downloading or will download and be 0MB in size therefor will not run.


When trying to update:
Using Windows Update - Updates seem to download then they fail with error message 80072EE2.
Java - error message stating installation failed or interrupted


Some flash works, but I get a green screen or glitchy video sometimes. For example I can watch some hulu videos online but not the ads?


Please I have been scrounging the internet for 3 days trying to fix this problem but most answers I find involve me downloading some sort of program or file which I am unable to do, it is driving me insane!!!


I just sold my xbox thinking I could use my computer for TV/Video but now I can't do hardly anything! I CANT EVEN WATCH DVD's ON THIS DAMN THING!

Please try following:

• Open an admin command prompt
• Copy/paste "sfc/scannow" (without quotes) and press enter
• When it finished reboot your system
• Open again an admin command prompt
• Enter sfc/scannow again

If sfc/scannow does NOT say "Windows Resource Protection did not find any integrity violation", please upload the cbs.log file located at {windows partition}\Windows\Logs\CBS\, if the file is too large try a 3rd party uploader like dropbox, onedrive, google drive, mediafire etc.
System File Check(SFC a.k.a. Windows Resource Protection) needs to have your system rebooted in order for sfc to try to fix the problems that it finds.
