ASUS laptop turns on with 6 images

Hello,

My laptop an ASUS F3S worked fine till this morning. Tried to turn it on and it showed 6 equal images with bad definition. They're the normal seen when a computer starts but divided and with blue stripes...then it all gets dark for a few seconds before restarting with the same 6 images. The fan continues working and the green lights are on as usual...Already tried with/without battery, with the main, the 45 second button thing more than 3 times, cleaned the dust...

Can someone help?
Thanks
Rita
