Q: My LCD monitor blacks out after about 20mins of being on and i need to turn it off for about 5min before it will come back on, then it only lasts for about 10min before it does it again. The screen goes really bright for a second before it blacks out. Could it be overheating?
A: Well, it maybe the your LCD might be over heating. If not, then I suggest that your graphics card might be having a problem. (most probably your graphics card is dying)
