Hey Guys, I just finished my first build recently. (Thanks for the help on that, by the way.) Everything is running stably, sans one what I hope to be minor, issue. The problem I'm having is once Windows starts my screen will pulse sporadically for 1-2 minutes, then the pulsing will slowly die down and eventually go away. It only happens right when my PC is started, and it never persists longer than a few minutes.
Some things I've tried: Updating the drivers (it happened before and after). Re-seating the card. Switching the cord from my PSU.
I'm not really sure what else to try, or if I should worry at all considering the issue doesn't last.
Anyways, here is my setup.
Windows 7 Home Premium 64-bit AMD Athlon II X3 435 2.9GHz MSI 760GM-E51 4.0 GB RAM SAPPHIRE Radeon HD 5770 500 Watt OCZ ModXStream PSU

This may be LCD display related. Can you check this by using a different display? It appears like a warm-up issue.
Try the video card in another computer to eliminate the video card.
