Does this freezing / slowing issue occur with or without the power adapter connected? Are you using an original Dell OEM power adapter?
For any slow boot issue = * Disconnect EVERY peripheral device from the laptop except the AC power cable. Then power on and retest * Turn on Fast startup in Windows Power options
Restart the system and press F12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. Also run the extended tests on the HDD and memory. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
If the system is still slow or tends to freeze then, restart the system and press F2 to enter BIOS - leave the system in BIOS with the power adapter plugged in for as long as possible and check if the system freezes while in BIOS - you would notice there is a system clock ticking in BIOS - if the system freezes, then the clock would have frozen as well.
