[請益] 進入遊戲沒多久就黑屏
今天打開BF3，玩完退出遊戲上BBS，突然畫面無預警黑屏，螢幕顯示DVI NO SIGNAL
主機沒有斷電，但按任何按鍵主機都沒反應，只能長壓電源重開
之後不管進入D3，BF3，大約過一兩分鐘後螢幕就黑屏，伴隨喇叭的刺耳剝剝聲
一樣只能強制關掉重開
驅動程式是nvidia最新301.42版，上個月灌完到昨天為止都正常
監控當機時cpu和gpu溫度大約只有50度上下
小弟配備大略如下
cpu: i7-870
vga: gtx 680
ram: 金士頓4g*4
psu: 650w
爬文看到黑屏的原因有顯卡，ram，psu等
請問以上述的症狀，最有可能發生問題的部分是哪裡呢
感激不盡!
