when it freezes at MUP.sys unplug the usb mouse. I googled around about MUP.sys in case it has to do something with it and tried these advices so far: Actually the same day I left it there, when they first looked at it everything was black and not responding, so they rebooted it which resulted in failure. This was the last time I see it working.Īfter 3 days they phoned me that the laptop is broken. I left the laptop there doing the defrag.

Next thing was running an ordinary defragmentation pass with perfect disk as the HDD was quite fragmented. Up to this point everything was working fine, in fact it was faster then ever (with the quantity of crap on it before the cleanup this is not suprising). After this running an offline defrag pass with perfect disk (the newest version).

What I did was running Ccleaner and reboot. I don’ know if I was the one who broke it, but according to her, I was the last one seeing it working. If I try to boot in safe mode it will freeze while loading MUP.sys (or after it, I dont know. Right now if I boot it normally, it will freeze at the loading screen (the one with the windows xp logo and black background) and after few minutes it will reboot. My friend has a Toshiba laptop, specifically a ‘p105-s9722’ and recently it has stoped working.
