595997 2007-09-28 07:31:00 So I bought all of the parts to build a new pc, consists of:

Intel Core 2 Duo E4300 Allendale 1.8GHz LGA 775 Processor.
OCZ GameXStream OCZ700GXSSLI ATX12V 700W Power Supply.
EVGA 122-CK-NF63-TR LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard.
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory (four sticks totaling 4g ram).
EVGA 256-P2-N625-AR GeForce 7900GS 256MB 256-bit GDDR3 PCI Express x16
HDCP Ready SLI Supported Video Card.

This is the first computer I've put together.

I've a fair amount of knowledge, enough to set up this pc, at least so I thought.

I've it all in my case, power to the processor, power to motherboard, hardrive connected, cd rom drive connected, graphics card connected. Power and data cables to everything.

Came down to the headers, I've power switch connected, I've reset switch connected. The HDD Led is connected, but the Pwr Led is not connected because it is three pronged or so. I didn't think that mattered to start the computer up anyway.

So I'm confused here, and asking for some help please, as to why my system won't boot up, it starts up for one second then shuts down.

I found out my problem was the risers, I had way too many put on and it was touching the motherboard, which explains why it came on and shut off like a second later.

Now I have the right risers connected correctly and only using which ones I need, it comes on, fans all spinning and on the led error it just says -- which means no error I do believe, but I've connected a video card and seem to be getting no connection through my monitor the screen remains blank/black.

So have I fried my motherboard? 		Norseguy (12873)
595998 2007-09-28 07:58:00 Possibly.

Only run one stick of RAM at a time until you sort it out. Try it with one, then try it with a different one. This will eliminate dodgy RAM as the problem.

Double check all connections. The power LED won't affect everything, but make sure the 4-pin or 8-pin ATX12V connector (near the CPU) is plugged in.

Check that your video card is in the right slot - only one will work. See the manual to find out which one, but it should be the one closest to the PSU. 		george12 (7)
595999 2007-09-28 08:05:00 Yes I've tried the card in all three slots and placed it back in the origional slot nearest the cpu, everything is pluged in and the cpu does have power. I've tried one stick of ram in two different slots of the four and have had the same results when trying for connection with the monitor. I tried it in Dimm slot 0 and Dimm slot 1(both blue colored slots). Norseguy (12873)

596001 2007-09-28 08:31:00 But I'm getting the same results.

Try this test -(it wont hurt anything) remove all RAM and turn it on - it should go beep beep beeep etc saying /Meaning no RAM. - then turn it off- Place 1 stick of RAM back in the Board.

Do the same with NO graphic Card - turn it on - it should go Nuts with Beeps.

If it doesn't theres a very good chance the boards fried - or its not getting power some where.

1 step at a time.


Techie stuff to test if all else failes ---- If you dont feal comfortable doing this then get someone who is.

One other thing you can do is remove the board assembly / cpu attached RAM Graphic Card Power Supply from the case. CAREFULLY put it back together on a bench on the antistatic bag the Board came in. Attach the Monitor to the graphic card.
No need to have a HD / Optical Drive attached, just the basic's turn on the main power, locate the pins that the case Power plug attaches to and short the two pins with a small screw driver - just touch them and the fans / board should fire up into life,- see if the board boots out of the case.
No need to get it running completely, just enough to see if something shows on the monitor. This will tell if there is something still shorting on the case. To turn off simply switch off the power.

Let us know what happens please. 		wainuitech (129)
596002 2007-09-28 08:34:00 Possibly your cpu may be overheating (heatsink not correctly fitted and/or no or not enough thermal paste on it) :horrified
This may help

Quite possibly.

You match the risers to the board BEFORE installing them. 		pctek (84)
596004 2007-09-28 11:24:00 Check the Video card. Most have a socket to plug in a lead from the power supply. Has the same symptoms .. all go but no picture. pheonix (36)
596005 2007-09-28 11:44:00 CAREFULLY put it back together on a bench on the antistatic bag the Board came in.

Ummm - don't anti-static bags work by keeping any electrostatic charge on the outside of the bag....? 		Deane F (8204)
596006 2007-09-28 11:46:00 From Wikipedia:

"To create the anti-static effect, the bags are slightly conductive, forming a Faraday cage around the item to be protected and preventing any localized charges from being deposited onto the protected devices as the bags are handled. It is important that the bags only be opened at static-free workstations."
