Please help me.
I bought a graphics 6870 hd from a friend.
my configuration is
intel e 6750
4 gb ram
asus p5k pro mainboard
lc power 500 watt
The card doesnt even allow my windows to start,not even a bios.I tried with chieftech 650 watt and nothing.Gave a card to my friend,and it works perfectly.Tried 3870 it works.Tried gf 8800 gts it works.Bios is the latest version.Tried on older mainboard msi 7502,the same problem happens.I have no idea what to do.Please help me.

Yes,I just tried it again.Took all his pc to my place.Put 6870 in his pc,working perfectly with crysis 3.
Put his power supply in my pc,nothing.And as i said bios version is the latest one
