Mame doesn't start

Hello there, new in this sub, read the rules and faq, checked some posts but didn't find anything similar to my problem (unless i missed it).

I was using older versions, 0.255 i think etc and roms always worked fine. But suddenly stopped working. I mean, screen goes blank like the old tv's when they lost signal and shows us that kind of "rain". After that nothing works, pc doesn't respond to keyboard, mouse or whatever! I have to shutdown in the case button. I didn't do any changes to my pc in terms of hardware of software. Updated to latest mame version, same problem. All drivers pc are updated. I put an image so you can see. Any idea of what's happening?
