Hi guys! Need help! So after I cleaned my PC it will turn on but no display on my monitor, no keyboard and mouse. Fans are working and lighting. I did try to plug the ram in another slot after cleaning it with a clean eraser but still not working. I also unplugged my videocard and use the cpu only and still not working. I also tried to take out the cmos batt unplug the pc and drain the electricity from my unit and plug it all again tried to turn it on but still doesn't work.
