Try downclocking the GPU a little bit, and see what happens.
I'll try this, but I've no experience with overclocking/downclocking -- will read up on it before doing it, though. Thanks for the suggestion.
Are you motherboard bios up to date? Which input method are you using hdmi or dvi? I would try using a different connection type first I have had problems with hdmi ports in the pass. And if that fails try seating the gpu in another Pci-e x16 slot and see if the problem still persist.
Going to go update my BIOS now.
Worried I'll do something wrong.
I'm assuming I should look at the BIOS Version/Date? The webpage for my mobo is http://www.asrock.com/mb/Intel/Z87%20Extreme4/?cat=Download&os=BIOS
and lists version 2.30 -- do I just download that one and use it? The scary "We don’t recommend users to update the BIOS if their system is already running normally. ASRock® assumes no responsibility for any damages caused by improper operations of downloading or updating the BIOS. Before you download or update the BIOS, please read " (How to Update)" below carefully." sure is intimidating.
I was originally using HDMI, but switched to DVI in hopes that it would help, but they both result in the same problem. I'll try reseating the GPU to the second/third PCI-E slot after I get my hands on that darned screwdriver. Thanks.
