    Hi people. I have a problem with my pc and I dont really know what can be wrong. Here we go: I turn my pc on and nothing appears in the screen. Although, the computers turn on normally, ie. all the fans start, cd drives etc. What can be wrong? Can it be the cpu? or the video card?

    Can you do like Highland3r says and post your system specs, also have you attempted overclocking, has this happened before, did it come on after leaving it a while, have you tried reseting the BIOS.

    Give as much info as possible, we might be able to help.

    I have removed the pc speaker so I dont really know. Although, the whole pc powers up normally and the drives/cds start spinning. I cant see why it can be a psu problem

    Specs:

    Athlon Tbred 1700+ DLT3C
    DFI INFINITY rev A+
    512 Corsair XMS3500 v1.1
    Enermax 550watt
    Western Digital 120gb SATA
    Pioneer 106s DVD
    Plextor CDR

    Try resetting the BIOS :thumb: Sounds like something just got borked somewhere allong the line. Did you install a new cpu perchance?

    I installed a new motherboard. I am thinking that it might be a video card problem after all

    We have the answer, windows will need to be reinstalled I'm afraid, unless you an get away with doing a repair install from the Windows CD


    When you change the motherboard windows needs a whole set of new drivers to function with that motherboard, very rarely will you get away without a fresh install, and even then its unlikely that it will be error free.

    Again, reset your BIOS. Reffer to your mother board manual for instructions on how to do this. It sounds like the BIOS doesn't want to work with something. Also, check all your IDE connections, I know if you hook an IDE ribbon up backwards, it will stall out a mobo :blush: Personal experience n all.... Anyway, does the board have onboard video, or is it a card?

    Sounds like the video card to me! Something similar happened to me recently- I took the graphics card out of the AGP slot, and then reinserted it again- and it worked fine- I think I had nudged the card slightly out of the slot!

    Does your pc make any beeps when it powers on? I know my mobo does a single "beep" to let me know that things are ok?

    As for the reinstall windows thing, you might be able to get away with the "repair windows" option- I did that and it worked for me!

    ;) John, try hooking the speaker back up, and see if there is a beep when you turn on the computer. If there is, then it's proably the vid card, if theres a series of beeps, then it's who knows what.


    [EDIT]Though, technicaly, if there is a single beep, it means the vid card is seen by the mobo, allong with the monitor, so umm :eyebrow: If you get a single beep, be scared. Anyway, take out the vid card and reinsert it, see if that helps anything.[/EDIT]

    I remember the first computer I built I hadn't put the video card in the whole way. Everything else came on but there was nothing on the screen.

    IIRC the GF2 MX doesn't work in AGP 3.0, due to voltage limitations provided by the AGP 3.0 slot. So I guess it's a video card problem.

    I'm sure they reduced the voltage in AGP 3.0

    edit: turns out they didn't after reading some .pdf's

    Update:
    Ok guys. For the last 3 days I am trying to get my rig up but still no success. Look:

    1700+ DLT3C @ DFI Infinity Rev A+
    512 Corsair XMS3500
    dvd cd-r hdds

    When I power up the pc. It starts but I dont get anything on the screen. In the beggining I suspected the video card but it works properly after all. I testd the ram and the psu (enermax 550w) in another pc and they work ok. So its either the cpu or the mobo. Is there any way to find out whats wrong? please let me know

    It's already been suggested, but I can't stress this enough, reinstall your PC speaker and see what the beeps are doing. Every motherboard has a list of system beeps and what they mean, it makes debugging SO much easier.

    However, if I had to guess, I would say vid card isn't pushed in all the way. Some mobos have a release switch on the AGP, others have it so the vid card has to "click twice" when pushing it down... most, you have to press down far harder than you'd expect.

    If that's not it, try reseeding Memory, try taking out all memory except a single stick, and if it still doesn't work, try another stick (like, it could be bad memory), try reseeding all your cards, or take them out (and just leave in vid card, memory, proc).

    But the system speaker (even if your dog ate the original one and you have to drag another case near your box to use it's PC speaker) would make your debugging 1098243481230 times easier, and that number is estimated and rounded down ;)

    Regards

    Ok guys. Update: I tried changing to aircooling in case there was something wrong with w/c. I only tried the board, gfx card, cpu, psu, memory. The system power up and after some seconds it power itself down (tried a couple of times with the same result). This reminds of some kind of overheating protection implementation but I cant see why the cpu would overheat itself with an Aero 7+ screaming above it and a high-end watercooling system cooling it to case temps.

    Tried just the board, the gfx card, mem, psu. The system didnt turn itself off this time, so I suspect its the cpu's prob.
    Btw, I dont know what "trimmed" means but I had to cut two of the washers to half their size in order to put them in the screws properly. Although, I cant see why this is bad and I am almost sure I didnt cause any physical damage to the board.

    P.S. I tried a second battery even though the voltmeter showed that the first one was ok. Still nothing.
    P.S2 Even I havent solved my problem yet you are really helping me to narrow down the fault. Thanks
    P.S3 I dont have a pc speaker available and there is no way I can find one.

    Btw, a pc speaker works by basicly faulting the ground wire. Use your multimeter ;) One side is 5v, the other will act like a ground. Watch the spikes, that'll tell you when it would beep normaly.

    Good suggestion from Mal

    Why did you unhook your speaker originally? Just wondering. See, a few years ago when I ran an Athlon 800, the board I bought was an Asus K7M (at the time, one of the best out there). About a month later they came out with the K7V and I was kicking myself b/c it was so much better than mine, but that's off subject. For some reason, and I never figured out why, after a while (and sometimes even immediately after boot) the PC Speaker would start constantly beeping (pulsing beep, not one big long beep) but the computer would still run fine. Finally I got pissed and unhooked the PC Speaker and would only hook it back up if I made a change and needed to hear the boot beeps to debug it.

    Was just wondering if you ahd the same problem ;)
