New pc build wont send signal to monitor. haven't seen the answer to help me on any other thread

[LiVingDeAdGurl9x]

Ok. I built a pc the other day and still have not been able to get the system to send a signal to any of the 2 monitors I have tried and a tv. The monitors I tried using both DVI and VGA cables and HDMI and VGA cables to connect to the TV. Still no luck. I have double and triple checked 5 hat everything is plugged in including the power to the GPU. I know that all the monitors and tv work because I use them for other things. I also have plugged into both GPU and mobo. I finally gave up and sent back the motherboard and cpu and got new ones. Still didn't help. I tried unplugging the GPU and just running through the mobo incase the GPU was DOA and it still didn't work. I then thought maybe if I take out the HDD and put it in my computer then install the OS and GPU drivers maybe that would work. I did that, put it back in the new PC and it still won't send a signal to monitors or tv. *sigh* So today I am back to trying to get it to work and I read a thread that said to test the ram. I thought well the system starts up and stays running but maybe it's the ram. I unplugged one ram and tried just the one ram. Then, just the other ram. Neither helped my situation, so I guess it could be both are bad or its something else. When I get home I will try taking the ram out of my computer and substituting. But in the mean time I hope some one has an idea to help me. I will also borrow the case speaker for my pc to use so I can actually hear if there are bios beeps. Final note. This is a pc for my friend I am building. I have already successfully built my pc and my boyfriends pcs so I am not super experienced but I do have a little bit of exprrience. PLEASE HELP!

It's got me stumped too, but I can tell you that bad ram (even no ram at all) wouldn't stop video signal being sent to the monitor.
Very puzzling that on-board video doesn't work either, despite changing the motherboard.

You've checked BIOS Setup for video output settings being correct?

I can't see BIOS setup because I can't get a video signal.

System specs?

Is there a bios speaker hooked up? If so, what beeps are you getting and/or debug code (if board has Dr. Debug)?

Could possibly be bent pins... won't know until you give specifics.

CPU
Board
RAM
GPU
HDD/SSD
PSU

just went through this the past two days.

use the vga cord from the GPU. turn the monitor onto the pc channel.

take out and put back in the ram, making sure it clicks down on both sides. also take out and put back in the GPU.

disconnect usb 3.0 cord from motherboard. turn on computer. I did this a few times and thought I had stuffed something in construction. . if that doesn't work try it all again and disconnect one of your memories also.

good luck
