New build, no post, no beeps, only fans..

[ChrisDiz]

Hi there, 

 

Please can someone help me?

 

I've just put a new pc build together, but it won't post or Beep. All the fans come on but the video card fans spool up, then down, then up and down again non stop. I've noticed the pipe to the radiator is getting very hot, almost too hot too touch. I don't know if I can hear any pump noise, as I've never heard it before..

 

I've stripped it back to motherboard, psu, 1x ram stick, cpu and cooler.. Still with no joy.

 

Could the pump in the cooler be screwed?

• Windows 10 pro 64bit (with intent..)
• msi x99a sli krait edition (BIOS version unknown.. Haven't got that far yet)
• Intel i7 5820k (stock speeds)
• Cryorig a40 ultimate 
• 2x8gb 2400 Kingston hyper X Fury ddr4
• Sapphire HD7770 vapor X (also tried with sapphire nitro r9 fury, same outcome)
• Samsung 950 pro m.2 ssd 256gb
• evga supernova 850 p2 platinme
• Enthoo Evolve atx

First verify every connection in the system.  Then do it again.

 

Try removing the RAM, then try booting with just one module installed.  If it still fails try the other.

Thanks for the reply! Yup, I've done these things more than twice.. How hot should the pump exit pipe get? Unless the mobo or cpu is dead on arrival, I have a hunch the aio cooler pump is busted. I had no idea before tonight, but the outlet pipe temperature is making me suspect the Cryorig. I just hope the cpu is still ok..

The cooler might have problems, but from a cold start that should not cause a failure to POST.

You may not have enough juice going through your system. How many watts is your PSU?

Also, make sure all the connections are correctly connected, and the CPU is properly seated.

if in doubt with an AIO cooler.. then try using intel's stock cooler.. 

i can see that you are not overclocking the cpu..

Does 5820k even come with a stock cooler?

 

Edit:  To the OP:  Do you have any other type of hard drive available?  If so try removing the M.2 and connecting the other one.

 

Last month I had a rebuild giving me fits because the Gigabyte MoBo did not like having a SATA M.2 present that already had data on it.  Once I pulled it and tried a drive on an ordinary SATA connection it worked fine, and then having gotten into BIOS was able to reinstall the M.2 drive.

I do have a spare mechanical hdd so I'll give it a go, but I've tried booting it without any drive in at all and it still has the same behaviour. I just cannot get to the bios screen. I bought a boss speaker and plugged it into the correct socket, and I'm getting no sounds from this speaker at all.

 

(The psu is an 850w platinum evga supernova.)

 

At the moment I have the MB on the motherboard box with the psu, cpu, cooler, ram, and video card. I've tried different combinations to no avail. Now I've disconnected everything and plugged the Cryorig aio pump up to the sata power connector (having disconnected the fans), and the sata cable to the psu. Using the psu tester socket, the psu fan winds up, but I can hear no noise whatsoever from the pump. I even turned the psu into economic mode to stop the fan spinning, and still I couldn't hear a prep out of the pump housing.

 

I figure the pump should at least be working in this instance, even if the pwm fans don't run.. right? Is the pump screwed? 

 

I'm tempted to just take the whole lot to a specialist as I just don't have the alternative parts to troubleshoot.

You might want to stop focusing on the pump.  The pump is not causing your system to fail to POST.  There is a problem somewhere between the PSU, the Mobo, the CPU, and the RAM.

Solved!!!

 

Aaaaand the problem was....

 

A tiny speck of dust in the cpu socket?! 

 

I'd checked all the pins with a torch up close, and they were all uniform, looked from different angles.. Looked ok. But the kicker was I called someone out.. They came during the daytime, and with the motherboard near the window, he saw this speck of dust which I hadn't seen at night.. A gust of compressed air and we moved it.. Then.. Posted to bios!! 

 

A £60 speck of dust later, then it overheated because the pump doesn't work. So, RMA in progress.. Hopefully it hasn't cooked the overclocking potential of the cpu eh?

 

So, video card fans turning on and off? Check the cpu socket for invisible dust.
