I have been experiencing a strange issue on my modern rig since yesterday - It powers on, the fans start, but there is no display and there doesn't seem to be any boot activity as the HDD led doesn't blink. Keyboard is unresponsive with inability to turn on the leds for num lock or caps lock. I unplugged all peripherals, cleared the CMOS, and since I own another LGA 1150 PC, I swapped video cards, ram, and cpu and still got the same problem. Loss of display signal happens with onboard graphic or with PCIE video card.
I initally blamed the mainboard (ASUS Z97-A) but decided to swap PSUs just in case, and managed to get the system to work. Moreover, when I used the "faulty" PSU to power on the other system (MSI H81M-E34), I got the same problem - system turns on but there is no video and no boot. The PSU is a less than 2 year old Corsair CX 600M.
I guess I always assumed that a PSU failure meant a complete inability to power on, but not something like the loss of video. Have any of you ever experienced a similar problem? Any info would be appreciated.
