HP Z210 sticks on boot requires Ctrl Alt Del to release it to boot

[speckytecky]

Bit of a strange issue here with a HP Z210 computer running 64 bit Wondows 7 Pro. It lost the OS completely. I've checked the HD and that's OK and reinstalled the OS completely.

 

If I press the power on button it starts fine apart from showing the PXE screen (rather it didn't) .

 

The problem, is. If I WOL the PC it powers on gets a HP splash screen then a PXE screen but after that hangs with the cursor flashing in the top left of the screen. It then hangs there with the cursor flashing but pressing Ctrl Alt Del sets it off to boot normally.

Flash your bios and check the boot order? Sticky key on the keyboard upsetting it?
