Ctrl-alt-delete combination and taskmgr.exe not working

[BigDaddy101]

It's been more than a month and my ctrl alt delete is still not working. I tried to run it from "run" but it still didn't work.

Ctrl alt del is not the only "ctrl alt" combination that doesn't work.
But the weird part is that both ctrl and alt only work separately. (ctrl+s ; ctrl+f + alt combinations)
