Please provide the rest of your specs. What is the brand and model of the "500W" PSU? Have you tried the paperclip test on it?

check these
Your power supply is properly connected to your motherboard
Your CPU is properly installed along with the CPU cooling source (fan)
Sounds like your RAM is properly inserted or your motherboard would be 'beeping' at you if you have the CMOS speaker plugged in
Video card is properly inserted (you might want to check the video card in another PC to ensure it works)
Unplug all other components (floppy, CD/DVD drive, RAID cards, use only 1 HDD and then boot)

I've updated the post and I'm fairly new so i don't know what a paperclip test is

I've tried most of these but I haven't applied thermal paste to my CPU yet and I don't have another PC to check the gpu.

You must install the CPU's HSF before powering on! You risk severe damage if you do not, although hopefully it would have shut down quickly enough.
