Black Screen Boot

[DntMrchOnMoscow]

My Pc hard froze so i turned it off. On boot up again nothing nothing on screen, fans power up and graphics cards also. Im running crossfire 5870 setup on a msi p67a-gd65 2600k @ 4.6ghz (been running at that clock for about 6 months with no problems) 8gb of1600mhz ram. I have already removed the crossfire bridge and connected each graphics card to a different monitor in an attempt to see if one was fried. Still nothing. Also should be mentioned that the motherboard leds go on for everything meaning i think that everything was running. What is my next step. Ps. It should be mentioned that the freeze was weird, the mouse lagged for about a minute then froze. Thanks for any help people can give

Sounds as though the board has died.

Try clearing the CMOS via the battery or the jumper. May have some effect.

Are their any beeps when you boot up?

But more of likely a dead board.
