    So i have a custom gaming pc and the specs are as follows.

    Ripjaws 16 gig DDr3 (4x4)
    ZOTAC Amp edition 550 ti
    Intel i7 2600k processor
    ASUS P6T SE motheboard
    Raid max 500w powersupply

    I recently had my motherboard power input wires sucked into my processor fan and all of the positive connections were cut. Of course the computer shut itself down immediately, and a red light that i had not seen before went on on my motherboard. Nothing will start up now, no fans, no processor, nothing. Tried resetting cmos and i took out the ups to try and reset the motherboard incase it was in sleep mode. After 2 days f fussing with it and doing everything i could think of (even replaced the power supply), nothing has come to fruition. I am getting no voltage from the psu and i dont know if i am supposed to when i measure it with a digital multimeter. Anyone know any possible fixes, willing to hear anything to save myself $250 at this point, thank you all in advance.

    Hi Nakri. Welcome to Computer Help Forums.

    I think it is best to take your computer to a repair shop and let them test the Mobo and all hardware components.
    There may be a small charge involved.

    By motherboard power input wires your referring to the 24 pin connector from the PSU?

    What text is under/around that red light?
    It should have something written on the motherboard to indicate what that error/red light means roughly, usually CPU/Processor, Memory etc

    You should also try (if you haven't already) removing all unneeded components/parts, so leave one RAM stick in, remove any HDD other than the HDD the OS is installed on, DVD Drives, USB Devices etc
    Just to see if you get any life from the PC, plus if possible try using another graphics card (maybe borrow one off a friend if you can) to rule out your graphics card being faulty.

    I'll assume the cable was plugged into the motherboard at the time when the CPU fan got hold of it, I don't know too much on the electrical side (I should know more with my Dad being an Electrician :blink:) but if as you say the positive wires were cut, maybe we're looking at some sort of electrical charge to the motherboard that may have fried it, as your hoping it isn't.
    See if anything comes of the above suggestions, otherwise I would then say the same has DSTM said with regards to getting it checked at a local PC repair shop.

    It was all of the positive wires on the 4 pin in the top right hand corner... There is no text on the light, just a red power button. Already tried the bare minimum and the gfx card didn't go bad, friend put it in his computer.

    Hi, first thing is to check the wires that were cut, I assume you rejoined them, if so make sure the connections are good and not just wire insulation trapped without connecting to the conductor inside the wires.

    If they are all correct, have you removed the motherboard from the case yet?
    I would be looking at the underside of the board for burn marks, just in case one of the thinner tracks got blown.

    How are you testing this ?

    Take a look here:

    You will - of course- need the PSU plugged in and switched on ( :) )

    If you are getting nothing or low voltages on the 12v / 5v rails then the problem lies with the PSU.
    The voltages should be within about 5% or so of what they should be.
    12v should be no less than 11.4 v ( approx )
