I have this problem with my Acer laptop. couple of days ago i was installing several IM sniffing porgrams for the LAN network, and after I rebooted the machine, neither the mousepad nor the keyboard would work, when i reach the logon screen. However, if I plug an external USB mouse, it wokrs just fine. I would assume same will hapen if I use
USB keyboard, just dont have one handy. Anyways, in Safe mode both the Mousepad and the keyboard work perfectly. Now I know for sure that it was the IM sniffing thing that messed the whole thing up, i reinstalled it, cleaned the registry, run scandisk, run virus check, did every basic thing. I also checked the device manager, because I assume that there is a device conflict, but there are no yellow ? marks there. I disabled the network cards and rebooted, no luck. anybody knows how to help me pls, because I can only work in safe mode, like now, and this is really annoying and its been like this for a week already. i checked similar threads, but neither solved my problem…
