New custom built PC will not turn off
Hi,
I recently built a new computer for my brother, and as of yesterday, the system will only power on, and the only way to power it off is by either turning off the PSU or unplugging the power cable, neither of which I feel particularly comfortable doing.
When the computer's power is off, the power can be turned on by pressing the power button. However, when the computer is on, pressing or holding in the power button does nothing. If the shutdown option is chosen from the start menu, the computer will go through the standard shutdown sequence, and the monitor will go to sleep, but the fans in the computer will continue to run. If the power button is pressed at this point, the computer will act as if it is turning on normally and boot into Windows properly.
This problem started late last night. Prior to then, the computer would shut down and power off normally. No hardware changes were made to the system between the last successful power down and the time in which this issue started.
System hardware:
OS: Windows 7 64-bit
RAM: 4GB DDR3 (Two 2GB sticks)
Processor: AMD Phenom II X2 560 Black Edition (3.3 GHz Dual Core)
PSU: Cooler Master RS-460-PSAR-J3
Motherboard: ASUS msq-m4n68t-mv2(b)
Hard Drive: Seagate Barracuda ES.2 500GB
GPU: NVidia GT250
