  1. Hey i'm new here and i've had A computer for like 2 years and it used to work but once I left it alone for a month I went to turn it on and it didnt work.... the monitor just stayed black....i checked every cord and there all in and I think it has something to do with the motherboard(i barely know anything about computers at all).. the mother board is a KM4M-V/KM4AM-V/KM3M-V series micro ATX mainboard and thats all I could think of putting in but I have every bit of info on it so if u need more info on the machine I can tell u it. Any suggestions PLEASE HELP! Just remember I dont know a lot but I do know more than an average chuck

    is it onboard video? or do u have a video card, perhaps try pulling everything out of the system and cleaning it, it might be dirty inside since u havent used it in awhile

    jsut get all the dust out DO NOT use a vaccum cleaner, just blow it out with ur own mouth if u dont have something like canned air around, make sure that the video card is pushed all they way into its slot as well

    I'll try cleaning it in a second but I just found out that nothing on the motherboard works cause it wouldnt read my keyboard or mouse either so i think that the plugs are the problem. Were is the video card? Here is a website of what the motherboard looks like and the insturctional booklet.

    the video card is the card that ur monitor plugs into...

    if ur monitor doesnt work, how would u know if it recognizes ur keyboard and/or mouse or not?

    When you turn your computer on does anything wirr to life at all?

    If not then I think your Power Supply mau have died, try using a different Power Supply from a friend or another pc you may have.

    As far as I know there is a word like wirr in the dictionary, maybe with a different spelling, but anyways. My english aint the best so I guess I may just have made up the word.

    I do however mean just like TOAD suggested any sounds or signs of life coming from your pc. Like you hard drive wirring/spinning to life and other lights flashing. That's what I meant.

    got it

    ok so i was having the same problem and i did everything you all mentioned BUT then i figured it out if you happen to have a video card which i see you do.
    you may just have been as dumb as me and plugged your screen into the "normal" spot there is a completely different space to plug it in lower yup its still blue try that out hope its fixed

    First of all, I sure hope problemman1225 come back and update us all.

    Secondly, every PC has a video card, some are built in/integrated with the motherboard and people still call it video "card". But I know what you are trying to say...if the PC has a built in video card and another video card installed then maybe he's plugging in at the wrong video card.

    Anyways, I don't think thats the problem because he said he didn't use the PC for awhile and when he came back its just won't start.

    The question is the PC even started at all hasn't been answered so we don't know the real problem.
