Well guys...
after 2 days of trying to get the PC to stay on....
it is finally working!! (i hope)
The problem I think was a low voltage readin from the PSUs (both Antec HE NEO 500W); the reading on the 12V rail was 11.71....
Now I bought a NEO POWER 480W and the reading is 11.98 and the computer is up and running!! w00t!
....apart from a couple of BSODs when windows booted up...still trying to figure out what could have given me those BSODs...

Thanks to all of those who helped me out!
