What does the beeping from my motherboard mean?

[Pie_ExMachina]

So today I finished using my computer and I accidentally click restart instead of shut down. Upon restarting it beeped twice in quick succession went quiet for a really short time and beeped twice again it wasn't detecting my peripherals and I was getting no video output. I have an intel dh77kc MOBO. I manually shut down my computer and tried again and same thing. I left my computer for about 5 minutes and went back to trying and it started up. What should I be worried about here? Anyone that has experienced something similar that could help me out? I did some research and it seems it could've been a problem with my gpu or my RAM but I'm not too sure at this point and the fact that it fixed itself has me more confused and a bit concerned that something could happen.
Any help would be appreciated.

Beeping might have something to do with RAM, try running a memory test and see if anything comes up.
