raster - DEM and vector data won't match using QGIS


I have just started using QGIS for my research at university. I have a DEM comprising Italian regions of Lazio, Tuscany and Umbria. I then have a set of vector data from surveys carried out in these territories. When I upload the DEM and survey data, I expect them to be on top of one another, but they are not. I tried everything but they just won't match! If I put a base map from Google Earth or Maps, the survey data matches the Italian regions they refer to, while the dem data ends up corresponding to Spain for some reason. I changed the coordinate references, to Monte Mario Italy 1, but nothing really changes: actually, the survey data just disappears from the map! It's probably something really stupid that I am messing up, but I tried every possible combination and I am getting quite frustrated!


Does anyone know what I can do to fix this?
