lg monitor black screen

Users questions: You master: my computer screen recently with the two-day boot is always a black screen when starting out. Computer can start normally, when I switch off the display can show after the opening, but there is a blank screen for five seconds or so. Would like to ask how do you do?
Experts answer: may be graphics related? If it is independent of significant Cards, may be the graphics card fan does not work (stopped) caused by high temperatures caused a black screen? You open the case lid, turn to see whether the graphics card fan turning? If you do not turn, buy a put to the same size fan. If it is not video card problem, maybe the memory problem?
