I bought new MSI GTX 770 and I installed it into main PCI-e slot in M5A97 r2.0 motherboard from asus, but my PC won't boot (it starts, but I cant access bios and it doesnt load windows) , but I put it in second PCI-e slot and it goes fine, but it is too close to PSU (PSU is mounter down and fan is taking air from inside of PC ) , PSU is 1,5 inch from Graphics card fan, I am afraid of air starvation, any help how can I put that Graphics card into main slot ? thanks
