Need Help! Can't boot up!!

I just started putting together my first system, but things are not going well. This is what I have hooked up in my case so far. Abit KT7 Raid, Kingston Value RAM, an old nVidia sound card (don?t know which) and Duron 700, and a monitor. When I hit the power button, the fans spin up, but that?s it. No beep sound or anything else. The video just shows ?no video signal detected, cable connected ok?. I tried all the DIMM slots. I tried my Ram in my roomates computer, and it was ok. I tried putting his Ram in my computer, I even tried both an AGP and a PCI video card. I have reseated the CPU several times.

I don?t know if this has anyting to do with it, it?s an InWin case, I don?t know the number off the top of my head. It came with a brass ?grounding? screw that is supposed to be screwed into the case. There are no other instructions for this. Is there anything in particular that is supposed to be grounded to this screw?

Another anomaly, is that the power button will turn on the computer, but won?t power it off. I have to turn off the power supply to turn off the computer. I rechecked the motherboard connections, and they look ok

Any suggestions anyone?

 
Remove everything but a Vid card/ram/cpu. See if it boots.

If not, remove the ram or the vid card and see if you get 2-3 short beeps and a long beep when you boot. That should tell you if your motherboard is good or bad.

If you don't get the beeps. Try completely removing everything, including the motherboard, from the case and carefully put the motherboard/ram/vid card/cpu back in and reconnect the header cables. I've had similar problems like this. Completely tore the computer down. Rebuilt it and it worked. No explaination as to why.. 🙂

is it a compaq case?, i recently had an expirierience with a compaq case and a new mobo, and i hate fixing compaq's, new ones are great, but compaq designs em to be a pain
 
One other thing you may want to try...btw thats what i always do when i get a new mobo...

sit it on a flat insulated surface... my latest was a tabletop... wood of course... plug in the video/cpu/ram and PSU... and just the pwr/pcspkr connectors and keyboard, and fire it up... eliminated all other variables this way, bad grounding, bad connections in the rset/hdled/pwrled..etc connectors.. no hd's no floppies, sound cards.. etc.. you get the idea..

If the mobo dont work then.. thats trouble...

You could also be grounding out the motherboard. If you pull the ram and get no beeps, try re-seating the processor then fire it up again to see if it beeps at you w/o ram. If that doenst work, re-mount the motherboard and see if you have any success.
 
I had a problem like this-ish where the case switch seems to be at fault. One mobo would supply power to fans but not show other life. Another wouldn't do anything at all. I do think your case is probably at fault. Calculated guess.
 
just what my problem was:
same mobo, with a thunderbird 1ghz... wouldnt get a signal at all to the monitor.
fans spun and everything

1) try a different monitor, sometimes its picky.

2) did you put the HSF on yourself? if so, take it off and examine the core closely, if there are any chips in it, you killed your processor... go get a new one.

that powerbutton problem isnt a problem, hold the button down for 4 seconds and it'll shut off.

and nVidia dosent make soundcards... 😀
