I am running windows xp /sp 2, athalonxp 2000+ cpu, 512meg ram, My mouse just stopped working. It dosnt even show up in device manager. I tried reinstalling chipset drivers, the os , everything I could think of and nothing will bring back my mouse. I checked my bios and there are no options to turn off serial devices. I tried a ps2 mouse. Nothing works..............HELP!!!

Practical, ordered checklist for a mouse that “disappeared” (hardware first, then OS). and correctly steered you toward BIOS and alternative mouse types; since has already exhausted basic reinstall/BIOS checks, the steps below isolate hardware, driver, and Windows-loading problems so the root cause can be found quickly.

Start with these quick checks from an elevated command prompt (run as Administrator). the first two lines force Device Manager to show ghosted/removed devices so you can see anything Windows still thinks exists:

SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
start devmgmt.msc

Then check that the core mouse/port drivers exist and whether the PS/2 and serial port services are present:

dir %windir%\system32\drivers\mouclass.sys
dir %windir%\system32\drivers\mouhid.sys
dir %windir%\system32\drivers\i8042prt.sys
dir %windir%\system32\drivers\sermouse.sys

sc query i8042prt
sc query sermouse

If mouclass/mouhid or i8042prt (PS/2 port) are missing or failing, Windows won’t present a local mouse; those are the standard class/port drivers for mice. (learn.microsoft.com)

Windows can also misidentify serial devices (GPS, etc.) as a serial mouse; that behavior and registry/workarounds are documented by Microsoft (see KB 283063). If the serial-mouse filter/driver is interfering, you can temporarily change its start type or disable it while testing—do this only as a diagnostic step and keep backups. (ftp.zx.net.nz)

Safe Mode only loads drivers listed under the SafeBoot keys; that makes Safe Mode a useful test but also means you may need to add a service name there to test a serial mouse in Safe Mode. Use SFC or expand from your XP install media to restore any missing system driver files. (learn.microsoft.com)

If all software checks fail, isolate hardware: try a known-good USB mouse (or a different machine), reseat/retry PS/2 only with the system powered off (PS/2 is not hotswappable), try a Linux live CD/USB to test outside Windows, or use a PCI/USB serial card if the onboard controller is dead. Start with the Device Manager visibility trick above and post the results (which drivers show and any Event Log errors) for the next diagnostic steps. (learn.microsoft.com)

Im pretty sure its system bio's. Boot up and hold DEL, then go in to mouse config (or what ever yours is labled) and looka round, for read etc etc, Its pretty simple to desipher it, just need to take the time to look over everything in there, also MS, and Nix can run fully with out a mouse, just a bit more work to it!

Hey man, it seems both types of mice (the only ones that have ever been created) do not work on your pc. Try getting a very standard older mouse anmd trying that), for the else part im very unsure.

I count three types of mice...
9 pin serial...
Round PS2
Flat USB

Did you try using a USB mouse...

I dont know of any system that does NOT allow you to turn the serial ports on and off...

I was talking more literal though. I dont know of many who use 9 pin. And yes the usb should work. If not you need to either look to a reformat, or calling the company.
