Hard to diagnose since it's my wifes machine... The machines power led was blinking like it was in sleep mode. I could not get the keyboard or mouse to wake it. I went ahead and unplugged the power cord and now I can't get the machine to power on at all. I tried removing all but 1 stick of ram etc. Doesn't seem to make a difference. When I plug the power cord in a red light towards the front of the case by the hard drive bay comes on for a split second and then goes away. I don't see any other power light indicators as if the motherboard is getting power... Machine was working fine previously. 1ssd, 1tb spindle disk, r9280x video card and 48gb ram is the setup. Any ideas? Any other way to boot the machine if the front panel button is the issue?
