Question Beep code on a dell optiplex 755

[leo.kerr300]

I recently tried to start my optiplex 755 sf after my power supply finally decided to die on my good computer and i got a beep code. The only thing out of the ordinary on it is theres a gigabyte gv-nx86t256h in the pci-e x16 slot(only put it in so i get opengl and shader model 4) and the cover for it is off(so the gpu fits in it). Also changed the ram to 8g. Nothing else has changed. I tried with out the gpu but still got the same beeps. I have no clue whatsoever this means so i hope someone else can understand it. Here's the link to recording(Might need vlc, google it if you don't have it).

Hard to tell if its 3 or 4 beeps in a sequence, but these are the most common beep codes.

1-3-1 through 2-4-4​	Memory not being properly identified or used​
4-3-1​	Memory failure above address 0FFFFh​

If you experience any of the following beep code errors, see Contacting Dell for instructions on obtaining technical assistance.

1-2-1​	Programmable interval timer failure​
1-2-2​	DMA initialization failure​
1-2-3​	DMA page register read/write failure​
1-3​	Video Memory Test failure​
1-3-1 through 2-4-4​	Memory not being properly identified or used​
3-1-1​	Slave DMA register failure​

Also tried clearing the bios settings. Still the same thing

And swapping the ram doesn't do anything either so its not ram related. Got out all of the 2G sticks and put a 1G stick in dimm_1.

Think i got a 'clearer' version of the recording here
