    I bought a brand new Samsung 330 Series 3 LCD HDTV and a 6' Dynex DVI to HDMI converter to use my TV as a monitor. I get home, my box is running fine, so I shut it down and set up the TV. I connect the DVI and HDMI ends and turn my computer on. No signal. After ruling out the TV as the problem I take out the DVI cable and plug my old 17'' LCD monitor back into my box using a DVI to VGA converter. No signal from either DVI port. I even bring in a 3rd 22''LCD monitor to test that on both DVI ports and nothing. I open the box and remove my Nvidia 8800 GTS graphics card and try the dedicated VGA graphics on the motherboard. No signal. I put everything back in its place and now I'm here. Does anyone have any ideas what could have happened between my box running fine all day to outputting no signal? When I turn it on with the 2 monitors and the 1 tv is recognizes that it is connected to something, but receiving no signal. I see no BIOS bootup screen or anything. When I boot up with the box open its clear that everything is at least "running" with some power going through it, hard drives, graphics cards, fans, are all going. I'm at a lost for ideas as to what happened to my box. Did I blow something inside by simply plugging in the converter cable!?

    Edit: Also, when I hit the power button it shuts right down, as if it hasn't booted anything at all. I hit the power and it turns right off.

    Hmm sounds like your computer isn't booting into windows to be honest, but that's only judging by the fact that it turns off immediately at the press of the power button, have you checked all cables and plugs? I would suggest if worst comes to worst you try taking out components and putting them back in.

    Also have you tested the graphics card on another computer?

    Does the machine give you a POST beep?

    the everything is running but nothing is happening scenario is usually Mobo, PSU or CPU.

    Before going down that road however, try, in no particular order, re-setting the BIOS, re-seating the RAM, re-seating the CPU, Reconnecting the PSU.

    You can also try booting the system with minimal things attached - eg mobo, cpu, ram, onboard vga, keyboard monitor mouse..

    Thanks for the replies, I found a site that suggested starting with only power adaptor and monitor plugged in like you said Golygus. It booted up fine, I plugged everything back in and was able to get to the Fedora 9 desktop just fine. Plugged everything in and it all worked like a charm, pretty wierd. Thanks a lot for the help :clap:

    sometimes computers throw hissy fits like that and nobody can explain why. my last computer wouldn't post for about 5 power-ups after having the ATX power connector disconnected (and reconnected, duh). after that, it booted fine and never gave any problems never crashing once or throwing weirdness. but disconnect the ATX connector and you had to do the 5 POST-less boots like clockwork. it was strange to say the least.

    my PC would doo this immediately following any kind of activity in the case (re-seating RAM, replacing PCI cards etc). Leaving it plugged in but turned off for twenty minutes fixed it. Madly enough, once i upgraded my PSU (was a cheapy cheapy 600W unit from ebuyer) to the OCZ one i have now, i can do whatever i like in the case and this never happens.

    funny that eh? cheap components, meh.
