I recently turned on my laptop(MEDION) to find that the monitor was displaying 2 rows with 3-4 mini screens of what the computer should be showing, i turned it off left it for a little while then turned it back on and it was fine, i have now got the same problem but i cannot find any way to resolve it. I would prefer not to reformat as i am a student and don't want to loose all my work, especially if it doesn't work any ideas would be great.
I just fixed this same problem on my HP dv6700. It turned out to be overheated ram. I ran the computer on just one dimm and it booted and ran fine. I then just switched the two dimm sticks in their slots and the laptop was back to working fine. Sometimes you get lucky.
