i have a computer and it was working fine
originally it was hooked up to a lcd
i brough it to my house to do some work on it
it booted up fine on crt monitor
then i pulled the card out
relized i could use it in the new pc
and put it back in to the same spot
since then
the display does not work

when i try to hook it up to a lcd
it gives me that analog digital box and then goes to no signal found
when i hook it up to the crt the monitor just doesnt turn on it stays in sleep mode

i have tried different monitors and they all do the same
i have tried 3 different video cards including the onboard
i have removed all the hardware to see if that would help
even removed the ram
no differance no matter what i do
seems like since i pulled the card out the video is not sending a signal out at all
even the on board acts the same way

ive reset the bios though the jumpers
did a power cycle where i unplugged it and help the power button for a few mins
tried hooking up the crt monitor though a adaptor to the dvi port
nothing seems to work

im running out of ideas

pls help

i cannot acess any loading screen so i cant get into windows , cant do safe mode ,cant acess the bios

is that mean the mobo is fried?
if so why does it turn on and hd spins up cdrom flashes and everything else seems normal
but no display signal what so ever

As suggested, the symptom set points at a motherboard- or power-distribution problem rather than a display configuration issue. The checklist below is focused on quick, reliable isolation so that the faulty part can be identified without needless swapping.

  1. Visual check - inspect the PCB around the PCIe/DVI area and the CPU socket for bent pins, cracked solder, bulging capacitors, scorch marks or a broken slot latch; also check for loose standoffs or stray screws that could short the board.
  2. Bench test (outside the case) - place the board on a nonconductive surface, connect only CPU+cooler, one RAM stick (in the recommended slot), 24-pin and CPU 4/8-pin power, and a speaker. Boot to see if any POST/beep/LED activity appears.
  3. POST feedback - an attached speaker or onboard POST LEDs give immediate diagnostic clues; consult the motherboard manual for code meanings. No beeps + fans spinning often implies early POST failure (mobo or CPU).
  4. Power verification - swap in a known-good PSU or use a simple ATX/rail tester. Some PSUs show nominal voltages idle but fail under load. Measuring rails is acceptable only if comfortable and careful.
  5. GPU isolation - confirm each discrete card in a known-good machine and/or try a known-good GPU here (ensure any 6/8-pin PCIe power is connected).
  6. CMOS hard-clear - remove the CMOS battery for 10+ minutes (more thorough than a quick jumper reset), then retry.
  7. Connector gotcha - passive DVI->VGA adapters do not work on DVI-D (digital-only) outputs; an active converter or the native cable must be used for analog displays.
  8. Last resort diagnostics - a POST/POST-code card or professional bench testing will distinguish a failed CPU from a failed motherboard; if all above fail, board replacement or RMA is the likely outcome.

Safety: always unplug mains and discharge capacitors before probing; use ESD protection. Following these steps narrows the fault quickly and avoids wasted parts purchases.

im guessing you damaged the pci slot when removing the first graphics card. if it has onboard video, connect via that and see if it boots, if not, i hope you have a warranty on the motherboard.

damaged a pci slot?? unlikely
also hooking it up with onboard doesnt make any differance
i already suspected there was something wrong with the mobo , is there a way to test to see if they pci or onboard vid is working , like with a voltometre for example?

i dont know what the voltage output is supposed to be for a pci slot but you should be able to use a volt meter on the internal pins. it does sound like a mobo issue.

When i said damaged a pci slot i didnt mean the pci slot itself but the connection under it, some can be notoriously bad. Its happend to me.
