Hello All
as-rock z77 extreme 4
HD 7870
i was gaming suddenly my pc crashed with a blank screen i manual restart i got a b2 error on my motherboard LED
i removed graphic card display attached to on-board video its works perfect
i attached my hd 7870 to different graphic slot same B2 error on my Mboard LED
i looked at my graphic card no damage no breakage seen. capacitors on hd 7870 didnt seem broken or puffed

my problem is how can i check if the problem is in my Mboard or graphic card {don't have a spare machine to check}

NOTE: with the b2 error fans on the graphic card seems working and gets a little worm
mow my pc is working fine on my board video output.1 year old graphic card please help

have you tried your 7870 in another pci slot on your board? you can also try it in another computer to see it still works.
