boot problem

[marin]

Hello,
I built this system about a month ago for my wife from parts I had after I upgraded my system.Its as follows:Abit BE6 II,PIII 550 Katmai(not overclocked),Maxtor5.7gig HDD,SB-16,SupraMax 56k modem,LinkSys NIC,STB Velocity 4400,128meg pc133.When I first assembled the system I couldn't get it to boot at all.The power supply would run and the cpu fan and the HDD would spin up but all I would get is a "No Video signal" on the monitor.I tried another videocard and swapped HDD cables.I tried new ram,I tried removing all the cards except the videocard.I was stumped and scratching my head.In frustration I walked away for awhile.I went back later and swapped back the cables for some brand new ones and tried it and it booted up.The system has ran fine until today.I fired it up
this morning and its back to the same way it was the day I built it."No video signal"I am out of ideas,any help
would be greatly appreciated.Thanx

If you arent getting any beeps try reseating the processor

Thanks for the response,I have tried that a few times.I get no beeps.I even tried another cpu,still
nothing.I'm wondering if the motherboard is toast?

I would imagine the video card would send at least a blank signal to the monitor if it was getting any power at all to the card. Sounds like the video card is not getting any power. Bad video card, or bad AGP/PCI bus.
That is just a hunch, not gospel.

I don't know if the STB is AGP or PCI, I'd assume AGP ...
Try a different AGP card if you can... Then try a good PCI video card if you can ... go from there.

Yeah the STB is AGP.I tried another AGP videocard,still nothing.I may go buy
a cheap PCI videocard and try it just to make sure.Thanks for responding.

Same thing happened to me last weekend when I try install my new videocard-radeon 64meg-
I ended up this way.
I took everything but c drive and 1 memory stick.
NO harddisk controller no,scsi controler, no sound card,nothing.
Put your C drive to Ide primary slot.
Leave 1 memory stick and put your videocard on agp slot.
then restart.
that's what i did and it worked.
after that I installed all my devices one by one.
It looks ok.
Be carefull when you put your videocard to agp slot.-I assume its an agp videocard-
One more tip:
When you want to add a hardware to your pc lay your tower horizontal.that way you can push your hardware to the slot that its belong to correctly.
Now I have another problem.
To help me please check my last post on technical help forums.

Try using a pencil eraser on contacts of video card to remove any dirt, etc. then re-seat the card. Make sure when you screw it down that the card don't pull up. This happened to me once and I did the above and also had to bend the screw mount somewhat.

Make sure the motherboard is mounted properly. Make sure no standoffs are touching motherboard where there isnt a hole.

Thanks for your help guys.The motherboard is fried.I removed the motherboard from the case and found a stand-off where there was no hole,it must have shorted out the traces and fried the board.I guess
I learned a $130.00 lesson.
