Hello everyone...
Whenever I switch on my computer, monitor light is just blinking & no display.. I thought it might be because of RAM.. But when I changed my computer's RAM , same problem arises.. And whenever i remove VGA cable from the CPU my monitor just blinks & displays "Cable not connected."
Please someone tell me what to do now...

If you did not get a different indication, then the motherboard is bad. When the motherboard POSTs, it should alarm that there is no RAM. The fact that you are not alarmed by the pcbthat there is no RAM, means it is is not POSTing. PoST means Power On Self Test. Take it to a technician to confirm.

The blinking light tells you there isn't any video input. Check video cable connections and make sure video card is seated in it's slot. If that's all right, it's probably a bad video card.

Press the menu button on the monitorx does a menu pop up? No? Monitor is bad. There, I have given two seperate methods to isolate the issue. Between checking the ram, connections, and pressing the menu button you should be able to determine where the issue is!
