Windows 7: Computer screen flashes at startup (not monitor prob)

Windows 7
Computer screen flashes at startup (not monitor prob)

My computer monitor flickers during the first 1-2 min of start-up. It will start at the Windows user-select screen and lasts into after Iíve logged in (unless I donít log in for enough time), lasting 1-2 min total. The flickers are quick, white, horizontal bars that stretch the width of my screen. Their height varies, but never covers the whole screen. When I restart, I donít have this problem, only booting up.
This is definitely not a monitor problem, as I have tested on multiple monitors and have the same problem.
I have a video of this, but itís in .AVI, which isnít supported on this forum. If anyone could tell me how to convert it into an acceptable format, I could do so.
Thanks in advance for any help you can provide!

As you have On-board Video you could also try that to rule out the Graphics issue ...
