Hi! I was having this problem with my G60, before it crashes several times then this blue screen appears then in the start up only sound can be heard but there is no display on the screen...then there is a time that i was able to operate it normally but crashes again..then i asked an IT and told me to check the RAM, this could be the problem..then i tried to checked it then i replace one of the ram... but after sometimes new problem arises...during idle time the screen turn black even if i already move the mouse or type in the keyboard still there is no display. My question is what could be the problem this time...could someone tell me what to do...

Thanks.
