for those decided not to do a fresh format, but want to improve the boot speed, consider optimizing boot up. here is how i do it (i have Acer 3820tg), some may not make sense for u:
1. remove Ms Office starter (i install Ms Office 2007)
2. remove antivirus (i install ThreatFire)
3. remove acrobat reader, acrobat.com, etc (i install acrobat 9 extended without LifeCycle)
4. remove Intel Raid
5. in device manager, disable Webcam (i dont use this - not sure help to speed up or not)
6. Download
Autoruns run as Administrator, disable the following:
- AmIcoSinglun64
- AthBtTray
- AtherosBtStack
- Acrobat Assistant 8.0
- Adobe Acrobat Speed Launcher
- Adobe ARM
- ArcadeMovieService
- BackupManager Tray
- MDS_Menu
- GREGService
- LMS
- Updater Service
7. Open Device Manager, go to Services, make the following "Automatic (Delayed start)"
- AtherosSvc
- Cyberlink RichVideo Service
- Inter ® Management & Security App
- NTI IScheduleSvc
- Acer ePower service
- Diagnostic Policy service
- Program compatibility assistant service
- Raw socket service (Acer VCM) (if u dont use webcam chat, can remove this)
- Threatfire
8. i also ran the
tool post by Eugine91
i now got in 23 seconds boot time! i probably can get a maximum a few more seconds if i start disabling card reader, devices etc and uninstall non-sense software like Acer Arcade, etc, which i dont use often. it's fast enough for me, and i prefer to have those software there, just in case if i want to use them
