Hi !

I bought this and it worked (start the OS too), but sometimes would not start (screen not tuned on). I decided to clean the motherboard using alcohol and cotton. When I finish this, I turned it on and now always the screen show this stripes (but always turn it on).

Should I wash better motherboard? (soap, water, toothbrush, hair dryer, ...)

Is there a solution for this problem?

Thanks in advance
