New PC build but fans only spin for one second and mobo has CPU error

My new PC is not booting. The light near the fan on the back of the case flashes blue for one second and spins for .5 seconds but then stops. The cpu fan also spins for .5 seconds. The mobo flashes red at the EZ Debug LED area for CPU. What do I do?

    I took it all apart and put it back together to no avail. The same thing happens. The CPU light flashes red for a second while the case fan flashes blue and everything shuts off. When I try to turn it back on again nothing happens. It flashes again only if I've unplugged and replugged the power supply.
  3. Can you list all of the specs please?

    Case – Thermaltake Commander G42 ATX Mid Tower Case

    CPU / Processor – Intel Skylake Core i5-6500 3.2GHz Quad-Core Processor

    Motherboard – MSI Computer Motherboard Micro ATX DDR4 LGA 1151 B150M MORTAR

    RAM – Kingston HyperX Fury Black 8GB (1 x 8GB) DDR4-2133 Memory

    Graphics Card – Gigabyte AMD R9 380 256 Bit GDDR5 4GB

    Hard Drive – Seagate Barracuda 1TB 3.5″ 7200RPM Internal Hard Drive

    Power Supply – EVGA 500W 80+ Certified ATX Power Supply
  5. Have you tried taking it out of the case and assembling it on the motherboard box? If it's shorting against the case, this should fix it. Try this without the GPU, too.

    Make 100% sure you've got the 8-pin CPU power connector plugged in.

    How would I test it after assembling in on the motherboard box? Sorry I'm a bit new to this and this is my first time building a new computer.
  7. Find the power button pins, and short them out with e.g. a screwdriver. This is basically what the power button does.
  8. 1. Take everything but the hard drives out of the case.
    2. Place only the motherboard, already installed CPU, and already installed ram on the motherboard. (make sure the CPU heatsink is on)
    3. Then, Take your power supply and plug everything in. (24-pin MB connector and 8-pin CPU connector). (Ensure tightness on the CPU connector)
    4. For this step you can either short the two power button pins with a screw driver or key or you can plug your case's power button onto the two pins.
    5. The system should start. Oh and make sure your monitor is plugged into the back of your motherboard and that your GPU is not plugged in right now..

    Which two power button pins would I short with the screwdriver? The ones connected to the case?

    EDIT: I've figured out which pins to short. Nothing happens when I short the pins, so what does this mean?
  10. If you did it correctly and it didn't turned on. That mean you got a dead PSU. If you bought recently, you still might be able to return it and get a new one. Btw, it was plug in and the switch was on right?

    Ah my mistake. It turns on for a split second like it originally did inside the case. A spot near the intel fan flashes blue and the EZ Debug LED flashes red next to CPU. When I try to short the pins again, nothing happens. It only happens again when I unplug and replug the power supply
  12. Something sketchy that you can try just be careful with it: https://www.youtube.com/watch?v=ixcWCrYpw3Y


    Do this with nothing plugged in but the PSU. Make sure the switch is off in the back when you are putting the paper clip in. Once it's in, turn the unit on. If the fan only spins a second you have a dead PSU.

    I tried this and the PSU fan did spin. I guess this means that the PSU is not the problem. What should I do now? Thank you all for your help so far!

    Take the CPU out of the motherboard if you have some thermal compound for when you put it back in. Check the motherboard for bent pins. Look very carefully.

    If that does nothing I suggest moving your Ram stick from slot 1 to 2 or from slot 2 to 1. Whichever way you didn't have before.

    Make sure your CPU Fan is in the CPU Fan header.
