Dec 4, 2013, 3:31 PM
Brand new computer.
i5 4670 CPU
Corsair 750 W power supply
Gigabyte ga z87x d3h motherboard
I turn the computer on, and it starts to boot and immediately shuts down. THen it repeats that cycle unless I unplug the PSU.
Things I have tried
Switching memory sticks
Unplugging everything except motherboard and PSU
Resetting CMOS by taking out the battery.
THe PSU was working 30 minutes ago when i took it from my old computer.
