There are many things that can slow down a startup.
- Disk Issues
- Corrupted System files
- Antivirus.
Open a CMD window as administrator and type:
chkdsk c:
If it find any problems, type:
chkdsk C: /f
It will say the disk is in use and if you want to schedule to next start = Yes
Restart
Then do a system file check:
Open a CMD window as administrator and type:
sfc /scannow

Could be a disk issue.
Use the Disk Diagnostic Tool from the HDD manufacturer's web site. Test the disk on another computer if necessary.
I wasn't able to locate Toshiba's Disk Diag Tool. Hopefully Acer's Western Digital Disk Diag Tool is helpful enough :/
