Ok so this is a long story so sorry for writing too much if it is.
So, 2 days ago i moved my pc to a different room only to find that my HDMI cable ad broken (literally the end had come off). i had no time to go out and buy a new HDMI cable and i didn't have another one, so stupidly i thought you know what i will unplug my graphics card and try to use integrated graphics, well after unplugging my current graphics card i plugged my VGA cable into mobo and booted up i got the 1 long 3 short beeps meaning something to do with graphics i think so now i think that this was a bad idea

So the next day i plug my graphics card back in and to my horror when i booted up the pc i heard no beeps and my pc was just in some weird sleep mode where it would instantly turn off at the press of the power button without the need of the power button being held down and of course there was no signal from my monitor.

After rummaging around a little bit i stumbled across one of my old graphics cards, i try this in my pc and hear one beep and my pc starts up however there is no signal from my monitor if my old graphics card is in HDMI but there is if its in VGA.

I just want to be able to use my newest graphics card, please help...

Newer Graphics Card: AMD 7950
Older : i'm not really sure but i'm confident its nvidia

sorry if my problem isn't clear just ask me to explain, any help is appreaciated.

Can you get into your Motherboard's BIOS? If so, ensure your Integrated Graphics Chipset is Enabled and then boot with that (while the Graphics Card is removed from the PC).

Uninstall all your old Graphics Card drivers, do a full reboot, download the latest (non-Beta) drivers from the manufacturer's website, install, power off, install the Graphics Card.

Hopefully that works, if not set your desktop resolution to 800 x 600 while Graphics Card is not installed, then install it and power on.

You could try disabling your Integrated Graphics via your BIOS' 'Peripherals' Menu.

However, if that doesn't result in your Graphics Card displaying correctly you'll need to reset your BIOS via the included CMOS reset switch or by removing the MoBo battery for 2 minutes then replacing it.

You could also check your BIOS for any PCI-E x16 or AGP related settings and make sure they aren't conflicting with each other or your Integrated Graphics settings.

Lastly, ensure your PCI-E x16 3.0 slot is free of dust and debris and that the Graphics Card is sat firmly and securely in its place with all the relevant PSU power-connectors attached securely.

Ok, I don't think anyone paid attention, he or she stated NO VIDEO at POST, thus uninstalling drivers would be a neat magic trick! (no video means you cant see the desktop) Also there is no way to get into the bios as well (Cant see with no video)
The Post error beep codes are telling the user there is a fault when the system is checking the following, Memory - Video - Keyboard. I recommend that you unplug all cables to every device such as hard drives, cd-rom drives, and unplug all boards from the mainboard. RE-SEAT the memory by taking them out, and pressing them back in, and run the system with only the power to the mainboard. All you need is Memory, Video, and a keyboard for a normal POST (Power on self test). Check your fan connections to the processor cooler as well, this must be plugged in.
If you can past the post in this method, then add one device at a time, test, and continue. If you plug a faulty device in it will fail the post so troubleshoot one device at a time. (Example, POST passes, until I plug in the PCI Modem card, then you have found your fault)

Pay attention to the way the cards are sitting in the slots. Cheap cases will cause cards to sit at an angle when they bend over time. Nice flush pins work better than a card that is flushed on one end and sticking in the air at the other.
