pc stuck in boot loop

post #1 of 15
Thread Starter 
hi guys mad.gif

finally put together my new build, and i cant get it to boot.

firstly, the specs;

i7 5960x
X99 SOC Champion
G.SKILL 4x8GB 3200cl14
SLI 980Ti
Cooler Master SIlent Pro 1200w
950 pro 512gb NVME + Raid 0 MX300 750gb SSDs.

custom watercooled, loop is filled, using the paperclip trick the fans turn on, pump works etc etc. put 24 pin into mobo, power buttons light up. try turning it on, nothing happens. nothing turns on, doesnt even start the POST process and the onboard debug LED doesnt even light up. im at a loss, have tried every cable again but im lost.

ps, cpu and psu are known working.

thanks for your help!


pc is now stuck in a boot loop, debug LED lights up but pc wont get to post before it restarts. have tried both bios's and clr_cmos switch. have to turn on with just cpu, board and psu, no beeps or anything, same issue. ***

Been there recently. I do not see a power button on your motherboard so have you tried to jump the 2 pins and see if it starts by bypassing the power button?

If not try that first

Next I would try removing all but 1 stick of ram and trying it in all slots. Try that with each stick of ram.

My guess would be a short when installing motherboard into case. Take it out and remount if you have tried everything else already. Make sure there is no loose motherboard standoffs or screws loose or missing

Sorry to say that disassembly is in order then. Take it apart and put a regular heatsink on it and see if it boots out of the case. I had the same thing happen recently on a z170 board and it was a bent pin in the cpu socket. But Skylake was known for that. Your problem is probably simpler. Look at socket pins if it will not boot out of case. Keep the test to the bare minimum. Board,psu,ram,cpu,heatsink,gpu if necessary.

If no boot and no bad pin detected look for someone to let you test your ram. or they let you test theirs in your rig.

did you look for a bent pin in the cpu socket?

you really need to find out if the ram is any good. Find someone that can help test it. A friend or local computer shop (which is what I did) or maybe someine on here lives close to you that can help
