Ok I decided to do a factory reset as i was a bit on edge on actually re-installing windows from somewhere else and not from the brand. It shuts down/sleeps/hibernate like a baby with the itus, perfect. :P
I gradually moved in with the windows updates and things seem to be fine. i left the atheros driver for last. and i dun see any of those problems yet after updating it.
but, my laptop had a bit of a overheating problem. I have a CPU temperature gadget running. and i notice its getting even hotter quicker while im not even doing anything really. i could have just 1 tab on chrome and its 90c when before i could have had like 20 tabs(dontask :P) and it would below 80c. i dont know if any of the updates could have this effect on it.
