Hey as title says my lcd on the motherboard started blinking and i cant turn on the comp. Was working fine, turned it off normally and now this. Have anyone tryed or heard about this? Cant find anything about it. Maybe the power supply is broken?
First, i'm pretty sure you mean LED not LCD? Also, which LED is this? Refer to your MoBo manual if you don't know.
What hardware do you have, in terms of RAM, PSU, GPU, processor, peripherals?
Try completely unplugging then replugging the PSU, then unplug everything but the MoBo, RAM, HDD, and GPU. Only use 1 stick of RAM. See if you can boot like that.
