Asus p6t deluxe v2 + i7 920 = blank screen

hey all,

Totally gutted. Was looking forward to playing on this wicked system but I get nothing on screen.No beep(not sure if mobo has built in speaker tho).

My components:
Asus P6t deluxe v2
i7 920
OCZ 6GB DDR3 1600Mhz OCZ3G1600LV6GK
640GB Caviar Black
corsairs 750w TX psu
sapphire hd 4890 oc

When I power up, everything whirls - cpu hsf is spinning, gpu fan spins+3 red leds on the gpu are on (not sure wot it means). However, the blue led near the dimm slots are not on. When I switch the power off, the dimm led flashes for a second.
I removed the HSF to see if the cpu was getting hot, and after leaving pc on with the blank screen for a minute or so, the cpu is already pretty warm. Is that normal?

I've tried the usual troubleshoots - remove everything and only try booting with cpu+gpu+psu+1 ram dimm(tried all 3 dimms that I have). Nothing. Nada. Monitor is blank. No beep, nothing flashing on mobo. Also tried clearing cmos jumper and removed cmos battery as well.

Also went through the "READ before posting about boot problems!" http://www.tomshardware.co.uk/forum/page-261145_13_0.html sticky. No joy...

I'm really frustrated. I've done a google, and I've seen some people with similar problems and the forum veterans imply that the p6t deluxe v2 boards have been shipping DOA or with half dead cmos batteries. I don't know...the board doesnt seem doa as everything else seems to connect. I don't have spare parts to test (e.g. extra RAM) further.

What do you guys suggest I do?

  1. I don't think that MB comes with a case speaker, and if your case doesn't have one, then you should buy one.

    http://www.pcloft.com/casespeaker.html

    Sounds like maybe a dead GPU, red lights typically aren't good. Did you happen to get a GPU manual? Either there or ATI support forums would be a good place to look for what the lights mean.
  2. couldn't find much info on hd 4890, but since its nearest to hd 4870, i searched for red led 4870 and came back with these:

    D1601 - Red LED On, shows critical temperature fault
    D1602 - Red LED On, shows External power connector A was removed
    D1603 - Red LED On, shows External power connector B was removed
    D601 - Red LED On, shows critical Core power fault

    Ive got similar numbers on my LED on my 4890, and its D1601,D1602 and D1603 thats lit up. I connected the 2 PSU pci-e 6pin cables and unplugged and replugged and its all the same. Also, I dont feel any rise in temperature when I put my hand hear the gpu fan.

    Arghhhhhhhhh.
    Dead GPU (because of the 3 LEDs)
    or
    Dead Mobo (because I don't get any blue led's lit up by the DIMM slots when pc is on. Not sure if it's meant to lit up though.)
    or
    Dead PSU? (because of both above)

    And I got the components from different suppliers too. No idea how to identify the problem without extra components. sniff sniff. ........my first build. epic fail.
  3. update: i just realised that optical mouse doesn't light up as when PC is turned on. Given all the previous symptoms mentioned, it's beginning to look like a mobo fault. Do you guys agree?
  4. Not completely. Its possible, but to really diagnose it you should get a case speaker, like the one I showed you above. I think it could still be the GPU. The mouse and other peripherals aren't necessarily going to turn on until the PC actually boots and goes through its POST, if you are getting an error before it can complete it then I don't think you would get power to your other periperals. It checks the GPU as part of the POST, so if that is sending an error, you fail the POST. Can you go to best buy or something and buy a cheap GPU (and maybe a case speaker too if they have them) just to test this out, and then return it later?
  5. Unfortunately, RMA's in the UK are not the easiest thing...not to mention getting pc parts easily. Wont be easy for me to get a cheap gpu at this stage. I've looked and looked at the p6t dlx v2 mobo and I can't for the life of me figure out where the pc speaker would be able to plug into. I don't see any suitable sockets =(
  6. There are two pins on the MB that the speaker would plug into.
  7. There is the big power cable and a smaller power cable for the motherboard.
    Makesure that on the smaller cable you are using the 8 pins and not just the 4 pins (pull cover off the 4 covered pins).

    Also like other have said you must buy a speakrer.

    Now if you pushed to hard on the motherboard when inserting memory or the HSF you can crack the mother board.
    I had this problem with my board and sent it back and got a new one and it worked fine.

    Good Luck

    Mark
  8. Yeah- I've kept the 24 pin EATXPWR plugged in properly, and the full 8pins for EATX12V. The CPU HSF spins, and when I remove the HSF, the CPU feels pretty warm too.

    Pushing hard on the mobo- might've been possible, but I was wary of using just about enough to push the new stubborn clips in.

    Still can't find the 2 pins to plug speaker in. MY mobo manual talks about BIOS beep coes, but doesn't meantion if a speaker is built in or not. Thank Asus for the ambiguous info.
  9. (wonder why I'm not allowed to edit my own post above..)

    Found the speaker points - it's on the asus q-connector socket, which is a detachable socket. hmm. Will see if I can get hold of a speaker at maplin. If mapling doesn't sell it, I'd have little chance of finding getting one any other place in the next few days. Might just RMA the board and GPU.

    By the way, my RAM is not on the QVL for my mobo. It should still work tho, right? That can't be the cause of all this? I should at least get it to post even if the RAM isn't on the list, right?
  10. Couple of possibilities (based on my experience with P6Tse, so yours may be different);

    1. The P6T has a speaker connection... it's just a question of whether the case has a speaker or not.

    2. The RAM needs to go in the slots AWAY from the CPU if you only have three, not the slots closest to the CPU.

    3. The Motherboard has TWO power connections; a big 20pin (or 24pin) one and a smaller 8pin one. BOTH must be connected.

    Good luck
  11. thx for the info siggy. found the speaker connection but case no speaker =(
    I've got the RAM in the slots away from the CPU - the orange slots. read the manual several times.

    i've got both 24 pin and 8 pin connected.... still no joy.

    woe is me.
  12. just so you know I am having the same exact problem, I have the ATI 4870 and I have 3 red lights and no display when I turn my PC on... if you search 3 red lights on ATI 4870 alot of people are having 3 red lights, I had an Antec case I called antec today and they are shipping me a Case speaker for free... I didn't even have to ask, I just called and said I have no case speaker, they said whats your address.. bamm 3-5 days I will have a speaker...
  13. I'm also experiencing the same issues with the ASUS P6T Deluxe V2 Motherboard.
    All my components are new and i tried everything suggested in the asus forums to fix this issue, including switching out video cards and still nothing!... So, I'm stuck in the same predicament. I heard from a mod in the asus forums that some of the ASUS P6T Deluxe V2 Motherboards are being shipped with dead or faulty CMOS 3v batteries.
    I'm thinking it's either that or it's my PSU. :sweat:
  14. gkoster, zaxis,
    I came across similar results on forums as you guys - dead gpu with 3 LEDs and asus p6t deluxe v2 with dead/faulty cmos batteries or even a dead mobo.

    I RMA-ed to my supplier and they've confirmed faulty parts - dead mobo. So far, they haven't reported a fault on the GPU, so the 3 LEDs may be attributed to dead mobo.

    I suggest you guys do the same and RMA. I tried troubleshooting a whole week and nothing came to pass.
  15. Sorry to hear your another victim of bad asus product gunsmoked.

    I tried a working PSU i borrowed from a friend and still same issue. which led me to the only real possible explination... BAD MOTHERBOARD!!

    looks like another RMA for me. :(
  16. i just experienced the same problem... no blue light by the memory sockets. my problem is a faulty PSU... of all things. the power lights came ond and everything else lit up like normal, however the blue light remained off. i switch to another PSU and the motheboard booted up like normal...
  17. Any one fixed this yet?
    I've just recieved a new replacment Asus p6T Deluxe V2 motherboard and i have the exact same problem. No post beep or display on the screen. I get beeps when i remove all the ram.

    please help

    Thank You!!!!

    I had the same problem and already did one rma...

    I guess I am a noob : ( all of my previous builds I had always placed the ram closest to the cpu.... changes it over the the other channel and it works like a charm !!!

    also is this something new with the x58 boards or just this one in particular...
  19. I have the exact same problem with a brand new computer.

    Asus P6T Deluxe V2
    i7 950
    12 Gb Patriot DDR3
    BFG GTX 280 OCX 1GB
    LG 22'' Monitor

    When I start my computer, my monitor goes to Power Savnig Mode and nothing happens. I thought it was because of my DVI connection after reading a lot of forums so since my video card only has DVI connectors, I switch to my old ATI card and eveything worked. I contacted BFG tech support and still waiting for an answer....seems that the mobo is not fully compatible with all video cards.

    Did someone resolve the problem yet?
  20. I also have the black screen of death problem ver similar to gunsmoked. My spec:
    Asus P6T Deluxe MoBo
    i7 920
    Sapphire HD4870 512MB
    3GB Crucial DDR3
    1TB Caviar Green
    be quiet Dark Power psu 650W

    I get 3 leds on the graphics card. Case fans all spin up as does CPU fan. The MoBo has onboard reset and power on/off buttons. Both these light up.
    The system was working ok for about 6 months. Then started to get no video output whatsoever on occasions. Rebooting solved this for a while. Now nothing at all. Have tried a different graphics card. This worked once, now same problem. Have cleared CMOS by jumper but no joy. Still can not get into BIOS even and machine wlll not POST. CPU was running at about 50c but believe that to be within tolerance. What is gong on? Any ideas/suggestions gratefully received, right now have very expensive paper-weight.
  21. I have the same problem. Everything seems fine. I have a blue light at the ram. I get a single beep but no Monitor signal. I have tried everything I can think of and read. HelPPPPPPPP

    Interesting to hear that your system ran for 6 months before these problems started. Mine has been running for about 2 months with a fairly similar spec and has just started to experience the same problem:
    http://www.tomshardware.com/forum/forum2.php?config=tomshardwareus.inc&cat=31&post=274584&page=1&p=1&sondage=0&owntopic=1&trash=0&trash_post=0&print=0&numreponse=0&quote_only=0&new=0&nojs=0

    I'm wondering if the CMOS battery is causing this problem? You have very similar symptoms to my machine with a different PSU, which was my other main candidate cause. Another suggestion I've picked up is the possibility of a short caused by a leak of thermal grease between heatsink and CPU hitting the MOBO or the back plate of the HS shorting. Unlikely I think, but worth checking. I've found that a CMOS reset brings mine back to life and it POSTs normally. It was running fine for 2 months with no problems at all, which suggests that the P6T may be the problem.
  23. Similar spec's P6T Deluxe V2, Core i7 920, but with an MSI GeForce 295 GTX. No POST, no beeps. Turns out it was a dead CMOS battery. Thanks for the help!

    It was definitely the CMOS battery on my machine too - once I'd changed it (and got it the RIGHT WAY ROUND :fou: it was fine...
  25. Hi,

    I bought new PC parts a couple days ago and get the same problem as said above. No POST, no display, no beep and no optical mouse/keyboard lights. The power button on the motherboard stays red when it's on or off. No lights by the RAM if that is meant to happen?


    Specs:
    ASUS P6T SE
    ATI Radeon HD 5770 VTX 1gb
    Intel i7 920 @ 2.66 ghz
    3x2gb Corsair TR3X6G1600C9
    600W ModXstream-Pro OCZ600MXSP

    The old compoenents are Seagate 400gb SATA HD and Lightscribe DVD-RW both which I know are working as I just took them out the old machine. I wish to fomat the HDD but as said, haven't even reached the BIOS or seen anything on screen!


    Attempted:
    Switching CMOS batteries (unless it has to be a specific type? I took it out my old HP)
    Motherboard CMOS jumper reset (I don't find this clear enough but I have attempted, maybe I did it wrong?)
    Putting in my old ATI Radeon x1300/x1600 series 512mb graphics card
    Removing all RAM, leaving only 1 in red slot A1, putting in B2, replacing that stick with one of the others


    A friend of mine said to get the latest BIOS and use a USB key to update.. but firstly theres no display to even do that unless it's automatic when I put the key in (please let me know), and secondly the light on the USB key, like the mouse, does not light up.

    I have yet to remove everything from the case and run it as such... just going to do that now.
  26. Well I was just being stupid, my problem was there are 2 power connections for the motherboard. The long one and a 4 pin one which is next to PSU... my bad!!!
  27. i had almost the same rig asus p6t and saphire 4890 2gb and 6gb ocz ram with the same issue.

    the reason for that was that the gpu required more power.

    At first , i connected only the pci-e from my power supply to the slot on the ati. The system started up, but nothing happened-just fans running at full speed.

    Then i connected the cable that was included with the gpu, to the 2 X 4pin connectors at the one end (for more power supply) and connected the other end to my second 6pin slot on the gpu that was still empty.

    It solved the problem.

    1pcie power supply ----> 1st 6pin slot on the gpu

    2 X 4pin -----> cable that was included with the gpu ------> 2nd 6pin slot on the gpu
