question about why mouse arrow sometimes doesn't move

[jimdagys]

I have Windows xp and sometimes (about 10%) of the time, after computer startup, the mouse doesn't respond. If I unplug the mouse and then plug back in, it will always solve the problem, so it is not a serious problem. I am just curious why this happens.

Could be a loose connection. Might be time to change the mouse.

also check in bios to see if its set for allow USB mouse and keyboard. thats assuming you have a usb mouse. if its PS/2 mouse then make sure the settings are correct in bios for that too. it will be very obvious in the bios if you look around what im talking about.

I have same problem in Win2k with PS2 mouse except unplug and replug doesn't fix it but reboot does.

@bevills1
Your ps2 connector has to support plug and play for it to work without a reboot. Probably most do but some don't.

@jimdagys
If it is a usb, you could try another port. If by chance you are using a ps2 I'd switch to a usb I've never had a mouse problem since going with an optical usb.
