I have a problem with QGIS 1.8 with OSGEO4W installer (windows 7 – 64 bit).
QGIS crash on startup, it shows the splash screen and then nothing.
I have updated from an old 1.7.4 QGIS version.
I have done the same procedure in a portable computer and it works fine.
The problem is only in the workstation.
Is there a log file to view what the problem is?

Today i stumbled on the same problem (Win 7 64-bit, QGis 1.8.0). In search of a solution i disabled all plugins (in the registry), deleted the .qgis folder, Qgis registry entries and reinstalled, but nothing helped. However, i had QGis working just fine about a week or two ago. My QGis was crashing when the splash screen displayed "Starting python" (or something similar) and i remembered that i recently upgraded from Python 2.7.2 to 2.7.4.
So, i reinstalled python 2.7.2, changed environment variables to point to python 2.7.2 and now my QGis works again. Check your python version, you might have the same problem.
