Hi, I have read all of the sticky threads but it seems I just don't understand what to do next: I have done all of the following only: 1. Downloaded a working bios mod from this forum. It contains the following files: Code: FLASHSPI.EXE -- DELL-DD981F15.XRM-MS -- 965PDS3_SLIC.F14 -- autoexec.bat . My BIOS is Gigabyte 965P DS3 version F14. 2. I used Gigabyte's official BIOS flashing app to flash 965PDS3_SLIC.F14 to the BIOS. My BIOS has been flashed with 965PDS3_SLIC.F14. SLIC Toolkit reveals: 3. I've ran Code: slmgr.vbs -ilc C:\965PDS3_F14_DELL and Code: slmgr.vbs -ipk <SLP key> However, my Windows 7 SP1 is still showing as a trial that will expire in 3 days. I would be grateful if someone could tell me precisely which steps I need to take next in order to activate my fresh installation of Windows 7 SP1. Thank you! SOLVED: I used a default key. Instead I used a set of keys available from the website 'techdoors.wordpress.com' - That key now works. Thanks!!
