Windows does not detect mouse.

From a cold startup, Windows does not detect mouse(MS wheelmouse optica PS/2). With a reboot, all is working fine. Happens every time...tried update driver(mainboard, mouse), registry edit from MSKB, stumped! Any suggestions would be welcome...T

Try deleting mouse & driver from the devmgr (winkey+break key). Try it while booting into safe mode (F5 during boot). Try putting it on the other ps/2 port (ie swap with keybd).

Nothing has resolved as yet...I have tried your above suggestions, latest 4 in 1 drivers from VIA, all MS updates(Win98SE), safe mode, swap, Searched Microsoft Knowledge Base...tried various fixes from similar problems. I have tried other PS/2 mouse(s), same result. Remain stumped...otherwise system runs errors in Device resource conflicts, etc., no BIOS problems I can find...thanx...T

Went back over things, tried using "optimized defaults" in the BIOS, which reset everything, after re-disableing the onboard sound(activated with the defaults) the PS/2 mouse is detected with a cold start...thankyou...drcspy...T
:-) ........yep I've found the 'defaults' option can often help...........

Yes, it seemed to help reset the BIOS, as I have put my settings specific to my hardware back in and the problem remains resolved...thanks again...T
