Shutdown after a few second

[TheGreyAngel]

ok so my pc was working just fine until i change my case AND my cpu cooler. Right now, when i click the power button, my computer start for a few second, then immediately shut down, then start again etc... i first thought it was the cpu cooler (went from 212 eve to h110) so i put the old one back, put it didn't work. What's going one? did my chip burn when i put the second cooler? did my motherboard is the problem? (fan are running btw). Thanks in advance for your answers. (sorry for bad english) 

 

Specs :

cpu: i5 4690k (not overclock)

mb : MSI Z97 Gaming 5 ATX LGA1150

psu: EVGA SUPERNOVA 750 G1 80 PLUS GOLD

Ram : Corsair Vengeance  8GB 2X4GB DDR3-1600

 

Plz help me

I would start with easy things. Did you try reseating the RAM or any expansion slot cards? Did you check to make sure the 20+4 pin and CPU 8 pin power are fully inserted? Other thoughts would be front I/O cables. Did you make sure you didn't plug a LED indicator onto the wrong pins for the front I/O? Other thoughts are remove the motherboard and check to make sure there aren't any extra standoffs installed under the motherboard that shouldn't be. You could check the I/O cover for the back ports. Make sure none of the metal tabs of the insert are jammed inside a USB port by mistake. Check every other power connector.

 

Those are my immediate ideas.

 I did try to change the ram, and i also changed the place of my graphic card, nothing. both the 8 pin and the 20+4pin are fully inserted. i'm pretty sure my I/O cable are correct, gonna double check that, my I/O shield is ok tho... guess i'm gonna to start all over again to check if the motherboard doesn't have any extra standoffs, but i highly doubt that

I doubt the standoffs too which is why I said start with easy things but it's still possible. A short under the board could cause the system to power cycle, /you could also try reseating the CPU but that's another thing to try as a last resort. You can try unplugging ALL peripherals (mouse/keyboard/monitors/speakers/etc) and starting the system to see if it changes anything. If all else fails you can try resetting CMOS. I know from my overclocking adventures failed overclocks can make the system go into a never-ending power cycling loop. Even if you don't overclock it could be a bug that resetting CMOS might help.

how can i reset my cpu and my CMOS?

re-seat not reset. Remove the CPU from its socket and put it back in. Resetting CMOS means resetting your BIOS. Sometimes motherboards have a button to reset the BIOS/CMOS, sometimes people just pull the battery which is on the motherboard. For you it's located just right of the MSI logo above the bottom-most PCI_ex16 slot. You can also go through the motherboard manual which will show you where a 3-pin jumper is on the board which you can use to reset the BIOS as well.

did everything you said, still not working

Now we try dumb things that might not change anything. See what happens if you put the old cooler back on.

just did it, nothing again... -,- guess i'm gonna be obligated to go to a computer shop to test all the pieces

Lets try these:

 

Remove all memory but one stick of RAM. Swamp sticks if that doesn't work.

Check under the CPU and inside the socket. Make sure no thermal compound or anything else is in between the CPU and the pins

So you reset the BIOS? Try it again. Move the jumper over one pin for 10 seconds then put it back.

Unplug all fans from the motherboard if there are any and see what happens.

Unplug all SATA cables from the motherboard.

 

If all of those fail...you might just have bricked your motherboard during the transfer process.

i did everything you said (thanks btw) except the BIOS, can't manage to find the jumper, i did a test with only 24pins and 8pins with everything deplug and same result

If you can't find the jumper you can remove the nickel shaped battery next to the MSI logo for about 30 seconds and put it back in. It will yield the same result.

will the computer is on?

No, turn it off. Unplug it from the wall. Remove the battery. Wait 30 seconds. Put it back in. See what happens.

I'm starting to suspect something died. Most likely the motherboard or the CPU.

same, but what about the psu?

I have reason to doubt that because the hardware configuration hasn't changed and a PSU isn't easily damaged unless you drop it from a hight however if there's nothing else to try you can try replacing the PSU.

ok, well lets hope the motherboard is eligible to RMA
