My laptop freezes only when plugged to ac and the nvidia driver installed, if plugged but no driver it works ,also if driver installed and on battery it works.
I have to mention that at first it was not working at all not even start the post and there was a whistle but now no whistle ans this happened.
When I plug it to ac nothing happen until I try to open any application so ever it freezes again. I tried a lot of different drivers and different windows even tried Linux.
It seems whenever the card try to do any graphics acceleration it does not communicate well with the system.
I suppose it could be - you can simply check the voltage of the adapter using a multimeter.
If you've reinstalled Windows and even installed Linux, it really should be a hardware problem, but I'm at a loss for what. The only other thing I could think of is that the power circuitry on your motherboard has gone bad, somehow, which generally never happens.
Well, if I were you at this point, I would probably strip down the notebook to a board, a stick of memory, the heatsink and fan, and your CPU. Using an external monitor and keyboard, I'd see if it froze on AC power. If that doesn't work, I would try another AC adapter. If that doesn't work, I'd probably replace the motherboard, if the saving of this notebook is worth it to you.
It is something either in the motherboard or the gpu.
I tried disabling powermizer all the time thinking it it is a problem of throttling but it froze even on battery when I enable it all the time it worked fine for sometime on ac but then froze again so it is just hardware and must be repaired or just use it with no graphics capablities.
