Frustration with new system build

Last response: in Systems
Share

Well I put together a nice new system on Black Friday from NewEgg, but I tried to get it setup today and was met with some serious frustration. Here's the rundown:

Antec Nine Hundred Case
Antec EA380 Power Supply
EVGA 01G-P3-N959-TR 9500GT 1G RAM Video Card
GIGABYTE GA-EP45-UD3R P45 775 Motherboard
INTEL C2Q Q6600 2.40G 775 8M Processor
SAMSUNG SH-S223F DVD Burner
Western Digital VelociRaptor WD3000GLFS Velociraptor HD
CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit

I got everything installed and the system would not POST. To make a long story short, I unplugged all of the drives and every single cable from the mobo with the exception of the one that went to the front-panel power switch and still no dice.

The power supply seemed to be working fine. When I hit the power switch on the Antec case, the system would power up, but just not post. I also could not use the power button to turn it back off, or use the reset button to reset it. Both were unresponsive.

Another interesting thing is that when I plugged the CPU fan cord into the fan header on the mobo which has a lead for speed control, the fan would not turn, but if I plugged it into one of the other (non-CPU) fan headers on the mobo it would spin just fine.

I made sure that the memory was in the correct slots and I also tried swapping with a different video card. Unfortunately I don't have another LGA775 processor handy to test with.

My guess is that the mobo is bad, but I wanted to check in with folks here before I went ahead and RMA'ed it. I'd hate to get a new mobo and still be in the same boat. Any advice would be greatly appreciated. Thanks!

Did you connect the 4-pin or 8-pin CPU power to the motherboard? I'm asking because the CPU fan doesn't spin when connected to the motherboard.


I'm using the stock Intel cooler. It has a 4-pin power cord and connector that comes off of it. I connected this to the CPU fan header on the GA-EP45-UD3R. Is this what you meant?

+1^

Also, I think the 4 pin cpu fan header should have a fan plugged into it, even if you only have a 3 pin fan.

Try using only one ram stick. One could be bad.

No, he meant that the psu will have a 8 pin power lead which must also be plugged into the mobo. The socket is white, and is located in the corner near the rear panel.
The 4 pin fan header on an intel stock cooler is a PWM(pulse width modulation) header and must be plugged into the 4 pin cpu header on the edge of the board.

Yes, I do see the 8-pin connector on the mobo, but these are the only connectors that my power supply provides:

Did I just not get the correct power supply for this mobo?

When in doubt, reread the motherboard manual. The 8 pin socket is compatible with the 4 pin psu power connector. The 8 pins are needed for high powered extreme cpu's. There should have been a cover on 4 of the pins. Plug your 4 pin psu cable in to the open half of the 8 pin receptacle. It should fit only one way. It is no doubt the reason you can't post.

First, rtfm. That's longtime techspeak for "read the freakin' manual".

Assuming that both power cables (the 24 pin and the 4/8 pin) are plugged in, the minimum configuration that you need to POST is the PSU, CPU and HSF, motherboard, a system speaker (which the Antec 900 does not have), and a way to turn on the PSU.

If this is working, you should hear a series of long single beeps indicating a memory failure. This means that the system completed a failed POST. If you do not hear anything, that mmeans that, in order of likelyhood, the PSU, motherboard, or CPU is bad.

You need a system speaker.

Me neither, roadrunner.
