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 Ive logged in (unless I dont 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 dont 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 its in .AVI, which isnt 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! d.png
