So I bought a GTX 770 to replace my GTX 650, on my PCI-express 2.0 Asrock H61M-HVS motherboard, Installed it and it powered on fans, green lights on the card, but no screen image at all.
So put my old card back in and window's wouldn't boot, it would freeze while loading. So I went into Bios and booted up in uefi mode and it worked but it made me delete my HD except for windows. And windows wont detect my speakers anymore, says theres nothing plugged in the 3.5mm jack... but it never moved. Replaced the drivers and nothing.
I RMA'd the card back to newegg thinking it was toast. But now I'm reading that it my be a bios update problem on my motherboard that needs to be done to make the 770 work. Any insight ?!
Here's the rest of the build.
i5-3350p @ 3.10Ghz
16gig of Gskill RAM
HX850w Corsiar PSU
