ok so this is my first post but i knoww you peeps will help me.

i purchased some new parts the other day and installed them and it wont work.

the parts i bought are:

4gb corsair dominator ddr2 1066mhz ram (2x2gb)
intel pentium dual core cpu @ 2.6ghz
500gb wd 5000rpm hdd
nvidia g210 512mb gpu
Asus P5G41C-M LX
coolermasters v8 cpu cooler
550w antec modular psu

i have put everything into the case, and turn it on and it boots for about a second and turns off.

so i thought this would be a faulty psu... ive tried it with my 750w corsair psu from my gaming rig and it still doesnt work, so i reinstalled the antec psu and connected the cooler hd optical drive direct to psu and used a jumper cable and all compenents run fine

so it is the motherbored that faulty ? right ?

if it helps when i installed the mother bored, the led on it was flashing for some unknown reason and i turned the psu on and off and it stayed on

thanks in advance for your help

Hi, welcome to Geeks

You May have a short on the Mobo..

Is the case old? Do the stand offs match you board?

Is the case new? Have you screwed the stand offs to the case to match the holes in your Mobo? Usually 6.

Have you connected the 12v AUX to the 4 pin header? Usually top left on the Mobo.

everything from the psu is connected properly... ive double and triple checked that

the case is brand new bought it with the parts... it supports micro atx (which the mother bored is) and is inserted correctly

i am considering taking it to peices and rebuilding it on the mother bored box to eliminate the chance of itt being a short.

i looked online and found some places suggesting it could be a faulty cpu which is over heating ??? i dont see how it would be possible due to it being on for a second, but thought id bring it up

[skitzodancer]

ive just tested the mother bored out of the case and the problem is still there.... now what, im considering taking this back to the supplier to exchange as it appears to have a case of deadsies

Did you do the bench test properly?
====================================================

Hook up the very basics, a "bench test":

* Remove the motherboard from the case and place it on a piece of cardboard
* Install only the CPU with heatsink and fan (remember to use thermal paste and plug in the fan)
* Install only 1 stick of ram in dimm 1 (consult your motherboard manual for which slot is to be used)
* Hook up the Power Supply (there should be a 20 or 24pin connector, and a 4 or 8pin connector)
* Use onboard video, (if not available, use a video card)
* Use any momentary case switch, or have your case close enough to install it's case switch
* Make sure there is a case speaker connected, many modern motherboards have a onboard speaker
* Connect a ps2 mouse and keyboard along with the monitor
* Power the system on


DO NOT hook up the hard drive, CD/DVD, case fans, lights, or anything else not mentioned above.

If the system does not power on, replace the 1 stick of RAM with the other stick. Are you getting any kind of beep codes? Do you get any video? Can you get to the BIOS? (Consult motherboard manual on how to enter the BIOS for your motherboard) Do the fans remain on, but no video?
======================================================

Did you apply thermopaste to the CPU and heatsink?

[skitzodancer]

i did apply thermal paste with the cpu cooler...

i didnt have my hdd connected or disc drive, however i didnt have the speaker connected so i will try that later and see if there are any beeps and tell post that later.

if there is no beeps what then ? and what if there are beeps ?

[Alzeimer]

Beeps if any will help you to know what might be the problem why your motherboard is not starting up.

Possible reasons for a mobo not to start at all:

Faulty motherboard, short motherboard, not connected properly MOBO
Faulty CPU, not compatible CPU
Faulty RAM, not compatible RAM
Faulty PSU

thanks for your help so far people... im in the process of taking the system to peices to make sure there are no wrong/loose connections

i seem to have localized the problem

i plug in the 24pin connector and plug this into my motherbored, then wire up the switch and it will turn on..... i then turn the system off and connect the 4 pin connector and then try to boot and this is when the problem starts... ive tried this with two psu's and the problem persists.

is this unsolvable or could the cpu be shorting out ?

Been to the Asus site, to check PSU and ram compatibility, but the link for your board appears not to work. found this site with some information, http://www.auspcmark...put[category_id]= also read some reviews with problems. some say the board needs an EATX PSU, don't know if that has something to do with the AUX 12v 4 pin? Also board is very picky about the ram.

Have you tried startup WITHOUT the video card and just the onboard VGA?

You did not say if you got any beeps when your system did start.

iv tried without the video card and still no luck

when i try to boot the system it is on for a second or less so there is no time to beep... but i can boot fine without the four pin connector.

im considering taking it back to the supplier.... its clearly faulty right ?

Some more info.

Use DDR3 memory modules on the black slots and DDR2 memory modules on the blue slots." Are you using the blue slots.
When you put the CPU in did you bend any pins? It is easy to do. You might want to check that.

This is what I found on the QVL (qualified vendor list)
