Windows 10: {Resolved} New downloads disappear after about a half hour post-download

I've been trying to download a large about 4.6 Gigabyte ZIP file. I was able to find it in the downloads folder when it was done, but after at least 30 minutes, the file goes missing and I have to re-download it. I can make a copy within that time and the copy is unaffected. Hidden files are shown and it doesn't affect past downloads.

Downloaded files disappear


When you download a file through any browser, there's an option somewhere to 'Open Containing Folder.'

In Windows, to find a file you have downloaded...

1. Open your personal folder by clicking the Start button and then clicking your user name at the top of the Start menu's right pane.
   
2. Double-click one of the following folders:
   
   • Downloads
     
   • Documents
     
   • Pictures
     
   • Videos
     
   • Music

If you do not see the file you are looking for, but know its file name, you can search for it by following these steps:
To search for a file you have downloaded...

1. Click the Start button
   
2. Type all or part of the file name into the Search box.
   The file you are looking for will appear in the list of results.

New here and seeking for help: problems with graphic card

Thanks very much lilhasselhoffer. I'll start doing what you suggested step by step.

One question thou: you suggested me to Download the latest driver package from Nvidea. However, the link you posted is for the newly released GeForce GTX 760? Am I supposed to download the drivers for that card?

Sorry for my questions. As I said, I'm not an expert at all.
