Okay, the board that you are trying to use is an HP motherboard so it's more than likely used.. Do you know if it worked before you got your hands on it?.. There is one bios update for the board but unless you can get a CPU that'll let it boot up you are pretty stuck.. Per the specs for your board you should be able to use the selected CPU here is the link to your specs and downloads.. hope this helps. http://h10025.www1.hp.com/ewfr...&docname=c01742903#N94
How are you so certain that this HP mtherboard supports a Phenom II 840 CPU?
The 840 is a relatively new CPU, so it's highly unlikely that it will ever support it.
Heck, I own three ASUS boards (including my Crosshair IV) that have yet to release a bios update that supports the 840.
You can clear the CMOS but I seiously doubt that it will do any good.
You may want to E-mail HP support requesting a bios update that would include the CPU code for the 840.
