Need help with my barebone kit please!

By thomasdog199 ·
Question. I recently bought a barebone kit through tigerdirect. I bought everything else it didn't come with (hd, cd-rom, better vid card, etc..). I finished building it today and to no avail, the damn thing won't turn on!!! I know it has power coming to it though because when I flip the switch on the PSU, the LED light next to the power button on the front of the computer turns green for a brief second or two. Then nothing happens after, I hit the power button and no results. I tried switching around my cables thinking I may have done something wrong, still no results. Anyone have any idea what this could be??? I've built ones before and never had this problem. Kinda lost actually, even tried switching around my neg/pos wires, and then no light appeared so I put it back to the original settings and am at step 1 again....

Much help would be needed and much thanks in advance!!

First thing is you need to edit out your E-Mail Address

It will get flooded with Spam if you don't do this smartly.

As you didn't make any mention of what hardware you have here it's a bit hard to offer much advice other than remove any Video Card you bought separately and pull the CPU out of it's socket and reseat it this time making sure it is correctly orientated.

Those are the most common things the Video Cards Chip Set causing a conflict with the M'Board Chip Set so the system fails to turn on or the CPU is incorrectly fitted to it's socket and isn't working.

Clear CMOS

by TheChas In reply to Need help with my barebon ...

Many motherboards ship with the clear CMOS jumper set to the clear position. Start by checking all of the jumpers on the motherboard.

Even if the jumper is set to the normal position, it still may be necessary to clear the CMOS so that the system will read the CPU code on the first boot and set the correct clock speeds.

Do you have all of the motherboard power connectors connected?
Some new motherboards have 3 different power connections that are required for the system to boot.

Is the AC line switch on the power supply set to the correct voltage?

It could be as simple as a bad power switch in the case. Try connecting the reset switch to the power switch pins on the motherboard. Or, even a jumper across the power switch pins.

If all else fails, go back to the motherboard manual and check all of your connections and hardware installations 1 at a time.

The next step I would take would be to test the power supply. Either with a power supply test box, or by substitution.

You might need to try disconnecting everything except the motherboard and video. Every once in a while, someone finds a drive power connector wired wrong.

You can go to hardwarebook.net to review the standard wire colors for computer power connectors.

If none of this works, please post back with detailed specifications of your hardware.
What motherboard, CPU, video card, Power supply, RAM is installed.

System Specs

by thomasdog199 In reply to Clear CMOS

Tried what the two of you suggested and still no juice. I even switched my power supply over from my old pc, and still received the same results. So here's my specs:
WD Caviar 160GB Serial ATA HD 7200/8MB/SATA 3G
MSI K9N6PGM2-V Motherboard - NVIDIA GeForce 6100, Socket AM2, MicroATX, Audio, Video, PCI Express, 10/100 Ethernet LAN, USB 2.0, Serial ATA, RAID
AMD Athlon 64 X2 5000+ Processor ADO5000IAA5DO - 2.60GHz, 1MB Cache, 1000MHz (2000 MT/s) FSB, Windsor, Dual-Core, Retail, Socket AM2, OEM Processor
Kingston 1024MB PC5400 DDR2 667MHz Memory (x2)
Power supply was the one that came standard with the case. Took out my vid card I received from my friend, just to keep everything standard. If you need anymore info let me know.

Thanks

Nevermind

by thomasdog199 In reply to System Specs

I was able to get it running. One of the fans were in the wrong spot so I fixed that.
Different question now :-(

THe pc will turn on and run when it's laying down, but when I stand it up and start to rotate it upwards, the pc shuts down and won't turn on. I am assuming it's due to a loose wire somewhere, any suggestions will be appreciated :-)

What kind of standoffs?

by ThumbsUp2 In reply to Nevermind

What kind of standoffs did you use for the motherboard? Are they tightened down? Look to see if one is loose causing a short.

Make sure your heatsink is secured onto the mobo correctly

by wanttocancel In reply to Nevermind

I had this happen to me and it was because I didn't secure the heatsink/fan combo to the mobo correctly so it would come off the CPU a little, the temp would rise too high and the computer would shut itself off to stop any damage from happening.

In Addition to Standoffs

by TheChas In reply to Nevermind

In addition to making sure that the right stand-offs were used and the motherboard is secure, check and make sure that EVERYTHING is fully seated.

RAM,
Power connectors,
CPU socket lever,
All plug-in cards.

It also could be a loose screw stuck between the case and the motherboard.

I would be looking at the Heatsink first

by OH Smeg In reply to Nevermind

Sometimes these are not correctly positioned on the M'Board and can sort of come away from the CPU when standing up or transporting computers.

Also check the CPU in it's socket here as if it is not correctly fitted & Locked into place it could be moving slightly and causing this to happen.

Also unplug the mains and pickup & shake the case for any rattles if there are any fish out the screw that got dropped and try again. Also make sure that the Power Plugs are correctly fitted to the M'Board and locked in place with their locking clips. Sometimes these can be tight to fit and not be fully inserted into their sockets. You need to be firm but not rough when assembling these things.

Also while not the cause of this problem make sure that any HDD's and Optical Drives are tightly screwed in place as you do not want these making a poor contact with the case and not shedding as much heat as possible into the case to keep them cool.

Look for any trapped wires or bare wires that may be moving around and causing a short to occur when they get moved by standing the case up.

There isn't much else that can go wrong when assembling one of these systems so it has to be one of what has been suggested above.
