Hold down the Ctrl key and the Shift key at the same time for a coupke seconds.
This... is the solution assuming the person is getting the aceent E instead of "?"

My first thought was language settings, but sounds like that's been eliminated.
Does Device Manager show any fault conditions?
Suggest the following:
1) Try an external USB keyboard. Use a Microsoft one as the drivers are native. Another make may require a download and a virus may block that.
2) Boot into Safe mode and see if you can correctly type.
3) Boot from the Windows install disk. This will bypass the OS (including any potential viruses) on your PC. Find a screen that lets you type and see if the ? mark appears. You can also boot from a Linux distro disk if you have one.
4) Uninstall the keyboard driver (in Device Manager) then reinstall (you may have to "discover new hardware").
I googled and apparently there are viruses that can mess with keyboards. TheDr's suggestions sound good.
If you suspect virus or malware it could have compromised your installed Norton. Go to http://housecall.trendmicro.com and run their free online scanner. the download Malwarebytes from https://www.malwarebytes.org/mwb-download/ free version is fine and run a full scan.
Checking your international settings and keyboard settings are correct in control panel also highly recommended along with a good blast under the keys with the canned air.
Please let us know when your problem goes away or if it's still an issue. I have come across this before and fixed it but I don't recall what I did. I don't want to go through all of the trouble of remembering what I did and posting print screens if it's fixed already.
Not fixed
that all the keys went at same time means it s not dust
I have no external keyboard so I must go to a pro for that test
