Is the motherboard chipset revision earlier than 'B3' ?
It is Rev 3.0 i crossed checked in speccy. this board is platform 1155 and it comes with SATA 2 only and USB2.0 only. It is running with Ivy Bridge Processor i3 3210 and 4 gb ddr3 @1333 mhz. Everything is at stock speed.
Worst is that if i use dedicated graphics, that is plugging my GT 240 and not using on-board graphics, when the system is idle, i can see the HDD LED (Red) always on with no blinks and after sometime it restarts itself giving me the error:
Windows has encountered a problem communicating with a device connected to your computer.
This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM that is failing. Make sure any removable storage is properly connected and then restart your computer. If you continue to recieve this message, contact the hardware manufacturer.
Info: An unexpected I/O error has occurred
That's how this board has ruined my old hard drive and now i know that it is going to eat my new 4 month old hard drive too.
