Mouse freezes at startup for like 10 mins everytime i start my pc.Also my date and time keeps going back to 2005 because of the CMOS battery failure.Is the battery problem related to the mouse problem?

Also my C drive free space is down to 1.5 gb.Is that the reason?n my windows is working too slow

I'd replace the battery and see if that fixes the issue, then if it doesn't I'd boot up in safe mode to see if the mouse continues to freeze. From there we can reinstall drivers and test.

Also my C drive free space is down to 1.5 gb.Is that the reason?n my windows is working too slow

Try to reinstall the driver or a different mouse.
C is also a way to move the empty disk or a different disk.

may I know your PC model? the reason why I asked is regarding CMOS issue, normally PC that more than 3years will have this kind of issue

Please follow this TS regarding Hang freeze issue

Regarding time and date, please check in your BIOS whether date and time is correct or not, if date time in BIOS is correct, I suspected its virus issue. If date and time in BIOS is incorrect its time to change the battery

based on my experienced, PC slow will also caused by bad HDD, virus or small free space

I suggest you free up some space to check the differences (my opinion free space = 20% HDD capacity or partition capacity)

then make sure your HDD working fine by defrag or check HDD health using built in app or any reliable 3rd partyapp.

last will be scan your PC, use reliable antivirus to detect virus or malware on your PC

I also find sometimes this issue will caused by 3rd party browser add-on. try to reset the browser to test, run browser without add-on or try at safe mode with networking
