Please Help! First time building went wrong!!!!!!!!

post #1 of 60
Thread Starter 
Here are my specs of a new pc i was ATTEMPTING to build.

460gtx windforce 2x 1gb
phenom II x4 955
M4A87T ASUS motherboard
G.SKILL DDR3 4G PC3-10600 HK (2Gx2) RAM
samsung f3 500gb HDD
some crap cd/dvd
[GIGABYTE] PoweRock 500W 80Plus
antec 200 case

Can i ask first of all, are all these parts compatible with each other? I just need a second opinion but when i checked, everything seemed to be compatible, most notably the RAM and CPU for the MOBO.

So i put together everything correctly (except for the cd/dvd because my case is weird and idk how to put it correctly so its basically kinda loose) and when i go to turn it on, it powers on for only 3 seconds literally and shuts its self off. Hopefully its not the PSU because i know its a crap one but still it should be more than enough for my specs right?

I tried everything from using on 1 piece of 2gb ram and booting but same thing and also tried without a gpu and same thing. Every single fan works for 3 seconds but turns off right after immediately. I really hope its not the psu but im really leaning towards that. When it shuts off, the power of the mobo still lights however so i dont think its my motherboard.

The only thing i can think of thats wrong is either i put the sata cables of the HDD and dvd/cd wrong or maybe because the cd/dvd is loose or the psu is dead or faulty or not enough power? or maybe its the motherboard. But these parts are all brand new but i know they can still be doa but im not 100% sure and i hope not.

Can someone provide me some help!!! i've been going crazy trying to fix it to the best of my knowledge but i cannot do this and also its my 1st time trying to build from scratch so its definitely harder than i thought.

Are the specs of my computer all compatible with each other?

Please ill accept any help ! or solution!

1) NEVER cheap out on the PSU. A bad one can fry your whole system faster than you can say "Crap, I shouldn't have cheaped out on the PSU."

2) Stupid (possibly insulting) question: Do you have the CPU cooler mounted and plugged in?

3) All that being said, 500W is really pushing it for that setup. Should have gone with a 750 to be safe.

Another possible simple error: make sure you have the 8pin CPU power connector plugged in.

Great point, but I don't think the 8pin not plugged in would shut down the CPU in 3 minutes...

OP it sounds like your PSU is undersized for the setup. Are you SURE that you seated the CPU and RAM properly?? If either of those are loose they can also cause some messed up issues.

What about the 24pin connector? is it all the way in? I say take it all out, relax yourself and put it all back in (boot the computer with just the mobo, RAM, CPU, and PSU hooked up). CHECK ALL CONNECTIONS!!

As for your question on compatibility yes the CPU, Mobo, & RAM are compatible. I still think you should try just the basics and forget the HD, GPU, and DVD/CD Drive for now. Get it into the BIOS first to make sure it all posts then plug in each of the components one at a time.

3 seconds. (as he stated in the OP)

4pin/8pin not being plugged in can cause that, however I'm thinking that maybe (with 460's in SLI) he's drawing more current than his PSU can supply.

Or, there's a short (did you install the motherboard stand-offs in your case?)

edit: saw that mobo/ram/cpu only will not power up...thinking it's a PSU issue.

hey my motherboard has 2 standoffs that are stuck to the mobo but the rest (4) is stuck on the case

is that weird or what?


i dont wanna sound stupid but does it maybe have to do with my cd/dvd reader not positioned correctly or the wires of the cd/dvd reader and the HDD are messed up? Probably not right?

Ahh sorry Reading > Me

You are right a 4pin setup can and will probably do that. But yes the PSU is undersized for an SLI setup.

*EDIT* OP I don't know of any motherboard that has the standoffs already attached?!?! maybe I am just out of the Mobo mix now-a-days. Usually they come with the cases...

Do you have access to another PSU? something in the 750w range if you want to SLI should be able to do it.

i only have 1 gpu though but my 460 gtx has 2 6pin connectors at the end of the card
do i need to plug in both to make it work as well? or can i just plug only 1 6pin connecter to it?
