Two nights ago, shut down the comp. After breakfast tried to boot it up, reached the bios splash screen and nothing. Won't respond, Took out the GPU(which was having problems, with being undervolted on default settings) unhooked all HDD and devices, just keyboard and monitor. Screen then just goes black like my monitor power button goes blue like it's about to start then yellow like it's sleeping.
Popped out ram and tried both sticks single, same problem.
If anyone has advice I'm listening because this is frustrating as hell.
