Help needed

When I right click on something on my computer, the screen goes black for a second. What gives? I changed the video card with the same results. This is a P4 with a gig of ram, but I do have 4 hard drives and a DVD-RW and DVD-rom.

That's strange. Is it when you right-click on anything? It's nothing that changes the resolution, like a game, is it? Is it just the act of right-clicking that does it?
