Will it load properly to that point? Once the desktop appears there are still some services and maybe startup programs loading. We start with safe mode and then add the additional items until we find a culprit. It can be a laborious process. There is also the possibility of a hardware or driver failure. I presume you've already tried system restore and last known good. I did just take in an old Fujitsu laptop with a similar issue but it never made it to the desktop. The final diagnosis turned up a failed hard drive. Replacing the drive and restoring a saved image to it fixed the problem.
Hey experts out there.
