I was working with my computer and was idle for about 1 & half hours. Then when I turned on monitor nothing appeared. Thinking that the system might have gone to sleep mode, I shake and clicked the mouse, pressed the enter button & then finally pressed the power button of cpu (my CPU has no restart button). Nothing happened. So I switched off the Mains & switched it on again. Now cpu produced 4 beeps & powerlight glows. But nothing appears in the screen. Monitor is ok . Data & power cables to monitor are ok... I switched off & on 4 to 5 times, after removing all other peripherals like mouse,.keyboard, speaker etc.. I even removed & put back the battery, also I pulled out ram modules and cleaned it and put them back.... Still those 4 beeps & nothing in the screen
