Not posting and no power led on Asus mobo

RenegadeTigger · Jul 6, 2013

Hey guys ive just finished my first build. and put everything together
specs are:

Asus P8Z77-v LX Motherboard
Intel 3570K
x2 8GB DDR3 Crucial Ram
GTX 660 Ti AMP GFX card
Corsair TX850M PCU
Corsair 600T case
180GB Sumsung SSD
Pinoneer BR RW

when i power up it all seams to run fine, fans runs there is a red led flashes once for the ram, and thats it. it wont post but seams to power my keybord and mouse??

after turing it on and having no luck i went back to square one and had a rebuild to make sure wires are where they should be and all is conected up.

im at a bit of a loss as to what to do now though and would love it if some one could shed some light on the problem and more importantly the salution!!
thanks guys

Try one stick of ram at a time. You might have a faulty stick. Also try resseting the cmos. Dont forget to turn off the power at the wall first.

Asus sets the ipgpu as main video output.try your monitor on the mb video ports. If there video go in and switch it to peg as first video device.
If there no fault led on and no output. Try one dimm and look at your mb bios rev. If it to low the mb won't have video output. If your mb has the USB flashback port you can update your bios using that port.

thanks guys ye i tryed with just one stick and i tryed it in the difrent suggested slots by asus but havent knotised any diffrents in the results yet

Pull Your gpu and see if the bios was to old to post with the gpu in. Try using onboard video. Also check that the eight pin pci power plug on the edge of the mb is plugged in.

cool i will try that now, oh how do you reset the cmos?? i havent tryed that yet. oh i tryed running the display through hdim on both the motherbord and gfx and now im trying through a vga cable on the mobo but it comes up no signle

hummmm, ive started it up with out the 660ti inside and no change so far. ive also found there is no sounds when starting up the pc... im very confused :S

Quick rundown.....check tat you used all the mb standoffs. Check that the io shield not shorting out the bottom or back of the mb ports. Check that the reset button on case not smashed in and the cables are on right on the mb header and USB ports. Check to see if case fan or Sata power ports are shorting out. Check that both the 24 and eight pin power plug is connected.
On the eight pin power make sure you dd not uses the power supply's six plus two cable.

Look at the mb bios rev sticker on the mb. If it an old bios and your mb has the asus USB flashback port download and update your bios.

RenegadeTigger · Jul 6, 2013

cool ive reinstalled the mobo, and its on all the standoffs and i think its not shorting out and its pretty snug in position the edge of the mobo comes close to the back of the case like under a mil close. im not too sure how to check my bios version without any monitor any sugestions?

Are you SURE 8 gig sticks are compatible? It sounds a lot on a four slot board. Yes, i am old.

RenegadeTigger · Jul 6, 2013

it say you can use 1, 2, 4 or 8GB non ECC DDR3 DIMMs into the sockets so i think im ok, but thanks anyway.

RenegadeTigger :

If the cpu fan is spinning up and everything seems to be working, then the ram is probably ok for the board. If the cpu fan doesnt spin up, maybe not.
There are different layouts of chips on the memory sticks, and you might possibly have a set of ram that wont work with 8gig sticks on that board. Its not common but its possible.
Borrow a smaller stick off a friend and you will be able to cross that problem off the list.

RenegadeTigger · Jul 6, 2013

when i start up it takes a moment for the cpu fan to start but then it runs just like all the case fans. thanks though. im a bit worryed it might be a fault in the mobo, there is no beeps or any thing when i turn it on.

RenegadeTigger :

If you cannot get a picture out of either the graphics card, or the onboard, I would try smaller ram and if it doesnt work send it back. Thats all i got.

RenegadeTigger · Jul 6, 2013

hey thanks dude i will try that just now, i realy apreshieate the help!! i got the mobo from ebay (a risky move) and it was sold as working but i dont think i will risk it again!! thanks again guys

chriss000 · Jul 6, 2013

RenegadeTigger :

Let us know how it turns out.
Good luck!
P.s. always buy new boards. .
2nd hand intel chips are good but not boards.

RenegadeTigger · Jul 6, 2013
