PC Troubles - No Signal to Screen

LibrarianLibrarian The face of liberal fascismRegistered User regular
in Help / Advice Forum
I built a newish PC for my dad with old parts and a new power supply.
The system is drawing power and starts up, all fans(CPU, GPU, Case, Power Supply) are running, the case display is on, the CD-ROM and harddrives seem to work.
The power supply is more than enough for the system, but the monitor gets no signal, no matter if I plug it into the onboard card or the extra graphics card.

So far I have:

- replugged the card and fans
- removed the reset switch because somewhere I read that this could cause trouble if not placed correctly
- made sure the RAM and everything else is in place
- unplugged the PC and pushed the power button for 1 minute(because somewhere it was suggested that this might discharge extra electric charge
- switched screens

Any ideas?

    Are there any beeps? Does the monitor power on and is just not receiving signal? What kind of motherboard?

    Test the monitor on another system. If it's a new graphics card, or monitor that is new to that set up, you may want to be aware that all DVI connections aren't created equally. Wikipedia DVI Page. You may want to try an HDMI cable. Also verify your graphics card is actually getting all of it's required juice. Many newer (and even some older) cards actually require two sets of connectors and/or adapted molex connections for PCI-E.

    It may not actually be a display issue, either.

    This is the Board. Tried different monitors already and both DVI connections on the card. We don't have a monitor with HDMI.

    Pull the video card and use the onboard. Often if a card is inserted bios will disable onboard.

    This isn't a solution as much as trying to isolate the problem. What model card is it?

    Edit: It actually says it disables onboard video if the pci-e slot is occupied on page 17-18 of the manual.

    I actually tried the onboard card already, as mentioned in the OP. Finally got it to work, had to reset the CMOS and put a new battery on the board and play with the other jumper on board for a bit, also as usual one of the connections to the board got mixed up.
    So thanks everyone, this can now be closed
