Screen not responding

[teh_mapn00b]

I just got a new 22" Acer LCD screen and I hooked it up to my also recently purchased 7600GT. It all worked fine for a few hours before I turned it off. I went on holidays for a week and get back to find that the screen and graphics card both seem to be working but the screen isnt getting a signal. I had this same problem about a month ago and I had got another graphics card (the 7600gt) just to fix it. Now its happening again! Please help!

Try moving your RAM around. It's happened to me before.

No good. I think that could be something to do with it though, as my rams always been a bit dodgy. I'll go borrow my freinds.
