I have Asus Laptop, running Windows 7 x64. Laptop work just fine, no malware, no other problems, except that battery is dead (battery still inside, laptop always plugged in AC).
Everywhere I go, to my clients, vacation, my living room ... laptop works normal, absolutely never had any issues, except when I work from my office room (which is in my house).
When I work in my office, the laptop freezes (hangs) for a couple of seconds once in a while. Freezing occurrence is random, sometimes freezes every couple of minutes, sometimes occurs every few hours, sometimes works just fine.
I have tried everything that crossed my mind. Temperature is OK, tried to adjust power management for some devices, tried to adjust various options for graphics acceleration switching, tried with LAN cable network with WIFI off, but nothing helps.
I need more hints, what to examine next, what can cause this freezes to happen? Note again - living room NO PROBLEMS, Office room PROBLEMS - Same house, same network same everything except the room.
