And you have a very old PSU. Try the onboard video (no, I didn't hunt down your system parts) and two other things.
1. Old PSU.
2. Old video card.
3. The usual forgot to remove ALL motherboard mounting posts to be sure only the ones we need are installed gaffe.
So i just bought a new motherboard and a new processor.
This is my specs now:
Intel i7 4770K
Kingston DDR3 4GB 1333Mhz
Geforce 8800 GTS
Power Supply is a LC6600 5 years old +/-
Ive a chassis fan on the front and back
Everything seems good but i got no image on the screen. No red lights on the board now warnings no nothing, everything is connected good. Double checked everything. Out of ideas now.
Thanks for your help
