I have an HP Prodesk 600 G2 mini pc but when I tried to turn it on it gave 3 long and 4 short beeps and wouldn't turn on. I checked that the RAM, SSD and processor were properly aligned but that didn't help either. What could be the problem?

It could be a problem with the power adapter.

 

See the troubleshooting guide at the link below for how to troubleshoot the 3.4 beep code error.
