Today all of a sudden GIMP started crashing while creating and saving a file with error: "Runtime Error! Program: c:\...gimp-2.8.exe this application has requested the runtime to terminate it in an unusual way ... etc..." This never happened before!
Yet I can open up a recent file - but I cannot save a file! I re-installed GIMP with a fresh download from original site - but it didn't make a difference. How can I fix this?

I'm running a win10 x64. I've been using GIMP for over a year and it's always worked fine.

And it also happens when you try to save a file?

Does it also happen on exporting to an image file format other than XCF?

Yes to both.
It happens after the "export image" dialogue window opens when I select "export as" from the menu. Even before I hit save or choose a file type. Just after the window opens it crashes.

And it really crashes, i.e. GIMP either vanishes completely and/or you get an error dialog?

If it hangs and doesn't do anything, then this could be that:

a none existing floppy drive? I'm working on a laptop - it never had a floppy drive. are you saying its BIOS definitions? I'll check into that.
there is an error message appearing, with all the gimp windows as they were, with an OK button on it. i press "ok" and then it shows a dialogue saying: "GNU Image manipulating program has stopped working a problem caused the program to stop working correctly. windows will close the program and notify you if a solution is available." with a "close program" button.
I press the button and that's all. Gimp is closed.

another detail: when it crashes because I chose to create a new file (open menu "file">choose "new") - it crashes not when I select a file from presets or choose size and hit ok - but after i choose "new". so it goes like this: I choose "file" in menu>I click on "new">a "create new image" dialogue pops up>some time passes (about half a minute)>it crashes with a message.

i did find an unknown device in the windows device manager and disabled it. then i restarted and got into bios. there was nothing suspicious there: no floppy no other thing. boot devices were ok (1st was usb; 2nd was hdd; 3rd was network i think; 4th floppy and 5th was something else. So i put floppy last. but I don't think it matters).

Then after it loaded it made the same error just like before so nothing's changed.

TOPIC SOLVED
what I did:
I uninstalled GIMP. then i removed its file in user folder, in program files and basically everywhere else i could find gimp related folders (found here: http://un-install.info/181288/uninstall-gimp.html. then restart and fresh installation. that's it.
