My computer just goes straight to a black screen immediately on startup.

At first, it was as if just the display stopped. If I was in the middle of a call on skype with someone, I could still talk to them just fine, and I could hear other programs I had running in the background at the time too.

Now, I can't even get to the desktop.

And the computer beeps at me when I try to start it up.

Stuff:
AMD Radeon R7 200 series
Intel Quad Core 8400
@ 2.67 GHZ
Processor LG 775
Asus PSQL/EPU
4 gb DDR2

How many memory modules do you have installed?

Remove the memory modules noting their locations. Clean the gold teeth lightly with a clean eraser. Make sure there is no corrosion or build up in the DIMM slots and reinstall the memory making sure to fully seat the modules until the locks completely engage. Re-test.

If the result is the same as before, and if you have more than one module, try using only one module at a time, making sure to use the correct slot for single module operation which should be the slot closest to the CPU or as marked on the board, DIMM slot A1. If that fails, try the module in DIMM slot B1.

If that fails, try the other module using the same procedure. If both modules fail or if you only have one module and...
How, exactly, does it beep. Number of beeps? Short? Long? Combination? I'd pretty much guarantee it's either the PSU or the GPU, but more information is needed to make a definite confirmation along with some further testing.

What is the brand and model number of the power supply. This is important.

One long beep, and three short beeps.
The power supply is a [strike]N500 LEPA.[/strike] LEPA N Series N500-SA 500W ATX12V.

If that fails, try the other module using the same procedure. If both modules fail or if you only have one module and neither slot results in the computer being able to POST, it's probable you have a memory issue.

There is however a chance that the beep code, which indicates a failure of the memory to initialize, could be a failed memory controller or a PSU that is not delivering sufficient voltage to the memory modules in order for them to be initialized.

That PSU model does not have great reviews and has a high rate of failure so it wouldn't surprise me if that was the issue. If you have or can borrow another decent quality known good PSU to test with that would be advised. Same for the memory.

You can test the PSU with a multi-meter if you have access to one by using the following methods:
