I went into my bios and I couldn't find anything to do with graphics? Would uninstalling the drivers then putting the card back in be a good idea or not? Thanks for all the help everyone!

getting no signal pre post is not software related. your display drivers are only loaded when windows does, everything before that is bios related. so no uninstalling drivers will not work. the fact it has worked and now doesnt means theres something missing/wrong.

the fact its got a direct relation to your optical drive would have me think your using a standard molex/sata lead to your optical and then an adapter on the same cable to your gpu? if this is the case run a seperate cable straight to the gpu. that is assuming you have actually got a 4/6 pin power cable connected to your gpu? sorry dont mean to sound condescending lol ive missed it off before!!

Was this AFTER a reboot?
I don't believe it is the psu, but I think it could have been something to do with the drivers, I can still get signal with my old card in. Thank you for reading and please help !

Pc specs: AMD a10 processor, 600watt psu, x2 3gb ddr3 ram, 500gb hard drive, nvidia GeForce gt 640 FFA card.
The first sentence doesn't sound logical to me, while I love AMD, I stayed away from the integrated gpu series for the very reason that I'm an nVidia fan-boy. I wonder if Windows is defaulting to the old drivers
for the previous card. PSU wouldn't be related to this. Ya got Radeon in one case, nVidia in another.
I confess I'm a hardware guy, not a software guy. Win7 has built-in drivers, a base, from which to upgrade to the most recent.
I'd have to go into your device manager to see what is going on.
Was the old card Radeon?
Try using the on-board choice in BIOS, in two steps, see if the device manager shows the old card
first, power down/off, swap, then see if windows acknowledges the presence of the new card.
Ya see, when I do a new build, I check to see if the BIOS lists all installed hardware first. Yet even on a fresh machine you should get the DOS/UEFI bios on screen, even on motherboards that do not have built-in VGA, you should see BIOS, on this build the mobo itself detected that the PCIe was in use and set it automatically. Only when everything is OK and set properly there do I go on to the OS.
You didn't mention what the old PCI card was but without further thought I think you might have a driver conflict. I'm going to need to think on this, for now I'm going back to watching my TV shows.
May I suggest a utility?
Get CPUID's HWMonitor @ majorgeeks.com it would at least let you see the voltage levels your PSU is putting out, though I don't think the problem is PSU or Optical drive related.
Is the card one of those gamer models that require an additional power plug?
Let me know.
The old card was a GeForce gt 620, and it is in currently. I cant find anything to do with graphics in the bios, What is a driver conflict? Thank you for your help

I would try HDMI if DVI is not working

The Igpu setting should be in the CPU section not the Graphics it 's a CPU resource you need to check all CPU settings
