Replaced PSU, beeping once, no video
So I previously posted about my iMac not booting up, thanks to some help I replaced the power supply and I have power and 3 LEDs. But now I'm trying to turn the thing on and get the fan noise and all that but the screen stays black and it continues to beep once every 4 seconds or so. I read that it's possibly a RAM issue, any suggestions or recommendations?
Thanks!
Is this a good question?

The 4th LED indicates that the LCD panel is connected and communicating. The Mac "should" boot with it disconnected but just for the sake of trying maybe disconnect/reconnect the LCD panel and attempt to power on again? The single beep is also a RAM error, you might try isolating the RAM by installing one DIMM at a time and trying to boot.

Well I'm guessing its the monitor if the last LED isn't on. I think I reconnected everything properly though..when I unplug the LCD temp thing the fan kicks on a lot faster, it might not be anything but I feel like something simple is wrong and idk what it is. Also don't know what a DIMM is. It boots up fine just no 4th LED and no display and it beeps once every few seconds..
