Have been using Adobe CC for some time - no problems at all. Then suddenly I'm getting BSOD every time I open Photoshop CC. Indesign & Illustrator run perfectly fine. All other applications & software on PC run perfectly. Just happening with Photoshop CC. All drivers are up to date. Checked for virus. Made no changes to PC at all prior to this starting 2 days ago. Restored back to last Windows updates (Dell thought it might be a corrupted windows update file) = not resolved. Uninstalled & reinstalled Photoshop = not resolved. Assigned my NVidia driver to Photoshop CC = not resolved. Uninstalled & reinstalled Nortons 360 = not resolved. Have run every internal test I can on my laptop = all hardware passed. Don't know what else to try! Message at dump is: KERNEL SECURITY CHECK FAILURE. Laptop is Alienware 17 R2, Windows 8.1, NVidia GTX 970. HELP!
