So I took off my towers panel so I could take out one of the RAM cards to see the type I'm running and the buy some more. I did that, put the ram back in, and now my computer won't start. I press the power button and it immediately shuts off the second I release the power button. Then it starts up again 3-5 seconds later on it's own. There is a beeping coming from inside the computer though as a warning I assume.
When it starts up the second time it sounds normal, besides the beeping, but nothing happens. The monitor doesn't display anything and is apparently receiving no signal as it is in standby mode.
What did I do wrong? What do I do to fix it?
P.S. - I'm on another computer obviously.
