Video Pulsing

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.
