More about system hangs half hour
  1. By hanging you mean totally crashed?

    Download core temp

    check you cpu temperature
  2. So you have disabled all power savings settings in windows?
  3. I prefer Hardware Monitor as it gives you all the system info you could possibly need.

    power saving settings tend to crash my pc..Never knew why.I had to turn it off.
  5. Check your stand by voltage (+5SB)

    Also check the USB devices connected to your PC. You may be overloading some of the port. At sleep/power sving mode only the +5SB is used to power whatever is on the USB port(i.e. keyboard, mice).

    Its common that the USB ports are overloaded.

    Recovery or wake up is dependent on the stand-by supply.
