No signal on monitor?

[usmantemuri]

Anybody had this happen? When the "No Signal" appears on the monitor and the monitor goes to sleep, the computer stays on but does nothing. I looked up the causes and cures on Youtube. Thought it would be the worst case, needing new graphic card. But I went through all the simple checks first. Cables, power supply voltages, clean out the dust from the fans and circuit boards using cotton swabs and auto MAF spray. Computer still didn't work. Went back in and pulled the RAM boards out, cleaned the terminals and stuck them back in. Turned on the computer and it now works. Whew, what a relief. I would have lost a lot of apps if I had to buy a new computer. This one is only 4 years old. Just thought I would mention it here so others will know about it.

Is there any chance that the settings are changed to an external monitor? It sounds as if you have checked most other things I would recommend. I assume you have checked all cables carefully.

yes, i have had faced this issue when i had newly bought the computer. At that time it was actually issue of monitor i had bought. Its setting was messed up inside. That is why it was happening. Another reason could be your power supply. It might not be supplying the power to the computer properly, that's hy Screen goes to sleep. Hope it helps.
