New Computer Build

Hello everyone, I think it's my first time here. haha. Well, anyways, I have a question to ask if yall don't mind listening.

I am trying the basic power supply, motherboard, cpu test, but all I'm getting is it to turn on for a few seconds, then off, then same thing. I was wondering what I should do next.

EDIT: I tested the power supply by jumping it, and that seems to be fine.

Thanks for your time,

Robert

What is the system, power supply and so on? Did you put all the standoffs under the board in the right places?
 
right now I'm doing an out of the case test.

system build:

intel i5 750
coolmaster 212+ cpu cooler
P55-USB3
4GB DDR3 1600 ADATA memory
wd caviar black hard drive
lite-on dvd drive
Geforce9500 GT graphics card

Power Supply: Thermaltake purepower 500w

And the power supply seems to be okay as I jumped it and it worked fine.

Try reseating your heatsink, you'll need to replace the thermal interface material if you do though,as your heatsink may not be contacting properly and it may be overheating. Also, ensure that you have the CPU power connector (EPS12v 4 or 8pin) and motherboard power connector (24pin atx power connector) securely seated.

I've just applied it today, should I re-apply it, or see if it is making contact?

Remove the heatsink, clean it off, and reapply it. The best method to use when applying thermal interface material is a small dot(roughly the size of two copper BB's) in the center of the heatsink, do not spread it, let the pressure from the heatsink spread it for you.

While you have your heatsink off, reseat your processor aswell.
 
Alright, will do. I did spread some thermal compound also in the gaps on the coolmaster 212+ as so many have said to do. Should this be okay?
 
I'm only doing a basic check. motherboard, power, cpu... and it wasn't working then, I'll try again.
 
Alright, I'll try the cpu pea technique thing tomorrow, getting late now. I'll update this once I test it. I might even try it with the stock cooler to see if that works, if so, then I'll switch back I guess.

If you reseated the cpu and its still occuring, then your problem is not with heatsink contact.

Next, if you have a multimeter i'd suggest checking the power supply voltages, it may be your power supply..(jumping it is essentially a no load situation).
 
Only thing I did was take-off and put back on the cooler, and the cpu. Seemed to go on easier, but still the same thing, I'll check the voltages then soon.
 
And what should each one have a volage of? Sorry for the dumb question, never have done it this way before.

About all of the connectors are at around 5.11 or so, except 1 or a few. And then of-course the no pin one. lol

Measure the voltage between the yellow(+12v) and black (Ground).
 
Nothing. I do get something though if I do the green one(with red) and use the black on a different one.

If you are not reading any +12v rail voltage when the power supply is running, the power supply is probably the culprit. (Ensure whatever multimeter you are using is set to a range high enough though, i've seen people accidentally use a 10vdc range and measuring nothing).
 
It's an auto ranging one. So the power supply must just not be getting enough volage to run the motherboard and CPU then, since it can run on it's own?

And I am pretty sure I am doing it right: Red to yellow, black to black?

I'll try using another power supply either tonight or tomorrow, I'll post back.

Might have found the problem...

Alright, I think I have found the problem, didn't have something connected, no clue how, but I didn't.

I'll post back if something occurs again. Thanks all for the help, and new techniques I have learned.

Thanks again,

Robert

Was it the EPS12v connector that you didnt have connected? Thats somewhat of a common mistake i've seen if so.(EPS12v is the Small 4pin or 8pin for the CPU).
