No video on boot-up

[clamum]

I just got a replacement motherboard because my old one had leaking capacitors. I took the old one out and put the new one in, connected up everything, and turned the computer on. It powers up normally, with no beeps, but the screen is blank. The monitor just says "No signal", and I know it works because I used it earlier today.

I've tried reseating the RAM, tried a different video card (AGP and PCI ones), unhooked everything except the essentials, took the motherboard out of the case in case it was shorting, and reseated the CPU. Nothing has worked so far. Right now I'm gonna try swapping the CPU with my brother's.

Anyone have any ideas? Thanks a ton.

i had the same problem with a new build. it was my power supply. the 5 volt rail died. if u have a power supply tester or a voltage meter to test it.

Oh I did try resetting the CMOS earlier XRdirtHead, I forgot the mention that.

Well my brother's CPU in that motherboard gave the same result, so I put my CPU, RAM, and video card into HIS motherboard and connected it up to my power supply. That booted up fine.

So I guess it's the motherboard. It was brand new too, sealed in the box. I actually got it from someone in the FS/FT forum... looks like it's going back.
