My Laptop lost 2 cores

post #1 of 14
Thread Starter 
Screenshot attached, as you can see task manager shows two cores with two hyperthreads, and hwmonitor only shows temps for 2 cores. Where did my other cores?? The laptop is set to high performance mode. Laptop specs in sig. Untitled.jpg 393k .jpg file

Check your BIOS to see if you enable all four cores.

Will try reinstalling the chipset drivers, the bios has limited functionality, no way to enable disable cores.

Reinstalled chipset drivers, made no difference.

Just incase it matters, its a Asus N73JQ-A1

What do you mean by my cpu being a joke, Im hardly laughing about it. Didnt know if there were any power options to try, even though Ive exhausted most. Thanks for the non constructive post.
