New Home-Built System Will Not POST

[Epsilon203]

Hi guys,

I finally god the opportunity to build my own computer and received everything about three weeks ago. I installed the hardware and started up the computer. The LEDs and fans all power on, but after about 5 seconds, the computer shuts itself down. The keyboard and mouse never power on. Repeat attempts yielded the same result. After several days of fighting this problem, I decided to return the motherboard for a replacement. I have since received the new one and, after installation, still have the same issue. I inspected the processor and there are no bent or damaged pins. Any info/help would be greatly appreciated. I'm at my wit's end. Thanks.

My setup:
ASUS Sabertooth 990FX r2.0 Motherboard
AMD 8-Core FX-9590 CPU
Silverstone ST85F-P 850W Power Supply
MSI Radeon R9 270X Graphics Card
G.Skill Ripjaws 8Gb (x4) RAM
Windows 7 Home Premium OpSys
SanDisk 128 Gb SSHD (dedicated for OpSys)
Pioneer BDR-2209 BluRay Burner Optical Drive

Dang, that FX 9590 though

1. Try to boot the system with just CPU/ATX power connectors, no GPU, no RAM, no storage, optical. There should be beeps for missing RAM.
2. Try to boot the system with power connectors and 1 stick of RAM, see if there's anymore beeps.
3. Try to boot with the above and the GPU, plug into each video ports, see if something comes up on screen. (Make sure the screen is on)
4. Try to boot up with the above and boot drive ONLY. See if it gets to OS.

Tell me where it stops at

Not saying this is definitely the issue but, that board has a max listed TDP of 140w. The 9590 goes well over that, IIRC it was somewhere around 240w.

In the CPU support list it even says "Due to the high TDP, please be noted there are limitations while using this CPU"

On another note, do you have any other GPUs to test it with? Or another PC to test the GPU in?

I removed everything but the motherboard, CPU, and power supply. Still the same result - lights come on, but after a few seconds it shuts itself off again.

Unfortunately I don't have any extra components to test on. I have my laptop, but doubt that it's of any use.

It would be quite frustrating if the motherboard was unable to hack it with the CPU since it was the recommended platform to use the processor with by NewEgg. They even came together as part of a deal package.

 

[IDontUnderstand]

So you boot the system with only CPU, motherboard, and PSU, but there was no beeps (if you have speaker installed) and it just shuts itself off?

What happens what you try to boot it with the above and 1 stick of RAM?

i am not seeing a cooler on that list. you need some pretty hefty cooling power for that beast, i am guessing you got one too small, forgot one, or installed it not quite right.
sounds like you are trying to run it without cooling, they shut down pretty fast when you do that.

also check to make sure you have the newest bios installed.
and that the revision 2 supports that chip, i know rev 3 does.
it should show either on the mobo or the box what bios it shipped with, if not look for a manufacture date and see if the newer bios release date if before or after the board was made.

 

[Epsilon203]

I don't have a motherboard speaker, so I can't say whether or not it is issuing a beep(s), but again, same scenario with one stick of memory installed. I do have cooling set up. It's a Thermaltake CLW 0223 liquid cooling system. The fans spin up but I can't tell if the pump is working or not.

 

[IDontUnderstand]

See if there's heat coming out of the cooler or just around the CPU block during that 5 seconds. Don't touch the board without discharging yourself first.

 

[Epsilon203]

There does not seem to be heat coming from either source. I powered it on several times to see if any heat built up, but I still don't feel a change in temperature.

 

[IDontUnderstand]

See if you can grab another PSU for cheap to test it, or I guess multimeter if that's easier for you.

 

[Epsilon203]

I'll see what I can do. Thanks for your help guys. As a last resort, do any of you have a recommendation for a replacement motherboard if it turns out that this one just isn't compatible?

 

[IDontUnderstand]

I think it's better to get a replacement for the processor as it is very hard to find a compatible one and also run the processor nice and cool while being stable. It's notorious for it's high heat output and power consumption and still unable to beat it's Intel competitor.
I recommend FX-8320 or FX-8350 for their 8 cores and still powerful.

If you would like to replace the motherboard, here is a link for compatibility. (personally never used this site, but it looks alright)

Good luck.

There are a couple of indispensable tools that are not very expensive and keep you from pulling out your hair 1 - a power supply connection tester, a 9v0lt battery with solid wires connected to it to test the 12 volt DC fans, ping tester, and one you can really use right now A post Card, plug it in to any PCI slot start it up and as it goes through the POST it will display a code to let you where it stopped during the post.
