Those connectors are for expansion, they are ok. If you are worried you can cover them in electrical tape.  Is there any beep when you turn on the pc? Does the cpu fan spin?  Try unplugging it from the mains and holding the power switch for 20 seconds then letting go and plugging in and trying again.  If you are confident enough you could try removing the cmos/bios battery, it looks like a watch battery, CR2032 will be the number. You could try taking that out making sure the pc is plugged out and turned off when you do.  Be careful and don't use metal screwdriver to lever it if, use plastic or wood shim if possible as it is safer. There are many videos online on how to do this. Leave it out for an hour then try starting without it in. If it starts you will get warning messages about your setup that you will need to read but they are ok. If that doesn't work then put the battery back in, making sure your are plugged out again.  Try again then.  If that doesn't work, try disconnecting the cables going into the back of the DVD.  Take pictures and notes if your are unsure so you can put them back ok, again there are plenty of videos online.  If that doesn't work, leave them out and do the same to the hard drive. The will be the same type and style of connectors.  If that doesn't work and you feel confident then you could remove the RAM and try again.  A green light on the power supply does not always mean it is working. If you had a spare you could try it.  You can get power supply testers cheap online.
