Fuck. got new RAM got new power supply still does the same shit.
It will turn run just fine without the RAM sticks.
When i plug in one RAM stick that i made sure is compatable with the gigabyte 970A-D3 MB it fucking derps and only turns on for a few seconds.
Make sure the ram is going into the correct channel. Say you got 4 channels some computers are particular into which channel you are inserting the ram.
example 0 = inserted ram, x = open slot
0xxx = correct for 1 stick
0x0x = correct for 2 sticks (can cause issues)
000x = 3
0000 = 4 (obviously)
Make absolutely positive its inserted correctly! (IE. not backwards)
And lastly, be VERY careful in handling your mobo and other parts of your computer, after turning off (or attempting to turn it on) your PC and unplugging it is recommended to hold the power button to bleed off any residual power remaining. It is unlikely, but removing or adding hardware with juice in your system can be damaging to your parts. Also remember you can give off static electricity, you can damage parts that way. (most 'hardcore' pc users will dismiss this, but the damage that can be caused is 99% of the time so minuscule that it will never be noticed.)
Also 2 important rules when using RAM of different types.
1. Larger Ram always goes first.
2. Ram channels should be set up like this.
slot 1 - 2gigstick
slot 2 - 1gigstick
slot 3 - 2gigstick
slot 4 - 1gigstick
having them other ways can cause issues
