What's going wrong??? Problem with motherboard or PSU? Others?

Hey guys,

I'm building an HTPC. I put everything together and there's something wrong. Nothing is showing up on the screen (tried onboard graphics and graphics card as well). I tried different several RAM sticks. Odd thing is when I turn the power button on the back of the PSU the entire system turns on. All the fans are running, CPU / graphics etc. - I even unplugged all the front panel connectors still same thing. Is there something wrong with the motherboard or PSU or something else? There is a green light on the motherboard so I don't think it's dead. Help me!

  1. Check all the connections to the lcd.
  2. Also post your PC specs.
  3. I checked the monitor it works fine with my other PC.

    Specs:

    Phenom II X4 830
    Asus M4N68T-M Mobo
    8GB Ripjaws RAM
    AMD HD 5670
    APEVIA PSU 500W that came with Case
    APEVIA QBOII Case
  4. I just tried another PSU that I know works and it still turns it on by itself. Bad board?
  5. I currently only have 3 things plugged into the motherboard:

    RAM
    CPU
    PSU

    Graphics is integrated.

    The PSU powers on automatically when I turn it on from the back. Everything else is unplugged from the mobo.

    Looks that way, unless u have a short somewhere.

    Check the PSU wires for the damage.

    BTW, do u have some critters like cats? My 2 cats would surely like to look inside.
  7. Just replaced CPU. Still same. Auto turns on. Mobo dead?
  8. Ok I took out the mobo and placed it on anti static plastic wrap and it's still turning on automatically. WTF?!

    I would get a new mobo. I have a dell laptop with a bad mobo and it does the same thing your system is doing. Turns on automatically when I plug in the power adapter =/

    It is strange as it could be.

    I would replace the mobo, before something will short out..
  11. I would suggest replacing the PSU as well. I can't seem to find a 80+ rating for that PSU

    He have tried another PSU, so there is a small chance that 2 PSU's would gone berserk.
  13. Yeah you're probably right. Just suggested it in the event that the case PSU messed up the mobo or something
  14. i do need some opinion as well. i'm also have a little problem with my system regarding turning on the PC, although not as severe as the first post. my problem is that every time i turn on my PC, (90% of the time) it will hang within booting the windows (between the first thing on the screen(BIOS/POST screen) until few seconds after i logged in to windows). what i normally do is to let it be for 5-or so minutes and then restart the system (i just call this "warming-up" time, LOL). restarting too early will not help either. after "warming-up the PC will boot normally, though the windows repair screen will come out

    i've tried formatting windows, it doesn't help
    is there a problem with the mobo? or is it my PSU is not enough for the system?
    my PC spec is as stated below:

    CPU : AMD Phenom X4 9550
    Mobo : ASUS M2N32-SLI Deluxe Wireless Edition
    RAM : 1x 2GB Kingston 2G-UDIMM DRR2
    1x 2GB Corsair Value Select VS2GB667D2 DDR2
    GPU : ASUS ENGTX460 DirectCU TOP 1GB DDR5
    HDD : Drive #1 - WDC WD6400AACS-00G8B (596 GB)
    Drive #2 - WDC WD10EARS-00Y5B1 (931 GB)
    Optical : Lite-On DVD-RW
    PSU : Cooler Master Extreme Power Plus 500W
    OS : Windows 7 Ultimate

    quite a mixed-up eh? i guess the rating for my PSU is 70+
