You "checked" the drivers, but did you follow directions that said, "even if you do have the latest, try reinstalling them"?  If not, do that now.  If your machine is using Intel Series 2000 drivers, however, don't bother.  There is no Intel 2000 upgrade that will make Windows 10 support the 3D graphics that SL requires. You will have to revert to your previous OS (Windows 7 or 8.1).

Since you are using the firestorm viewer, post in the Firestorm support group. They may a solution. See Firestorm Viewer.

Also, try installing the Linden Viewer and see if it will allow you to run.

Also, you didn't give us any informaion to work with. If you are using an older Firestorm, it may be one of the blocked versions. Make sure you have the latest Firestorm version.

You didn't tell us what vide card and driver you are  using, so we can't help there. Try looking at the SL System Requirements.

Whenever asking a tech question, include information about your computer and viewer. Generally we get that from the viewer's HELP->ABOUT... If the viewer will run at all that is the place to get it. You don't have to login to get it. But, the viewer does have to run. There are other programs that will collect all that info. Without it we can't help much. We are left guessing.
