Sapphire HD7850 OC 2gb
Now the problem is, after installing the hd7850, the pc wont post or boot, not even bios, it just black screen, and i can boot in windows fine with intel hd graphic or another hd7850 (non-oc) from my friend.
550w should be more than enough for a hd7850 oc and what i have tried are:
setting the bios
check the power connector
is it clear for me to declare it is a bad or faulty gpu?
