When I turn my PC on and off, the mouse pointer remains frozen.
Unfortunately, I do not have a Windows XP CD; the PC was delivered to me like this.
I am indeed afraid that some system files may be corrupted.

Hello
often such a problem is a problem of damaged files,
and you need to reinstall the system!
if you tried with another mouse and it doesn’t work!!!

but if you turn off your PC and then turn it back on, what is the reaction?
does your mouse remain frozen!
because without the mouse you can't do anything!
