I have had this no display problem for a while now. I took the PC into a shop they told me most likely motherboard, so I ordered replacement motherboard which came with a new CPU installed everything still no display. It powers up but no display. So I take it to another shop today, they tell me most likely PSU, so I buy a used but in good condition, power supply from that place, bring it home and install it, and still no video. I do not want to give up on this but I am out of ideas to fix it, and I am tired of spending money on it and it not working. So, I need some help with something that I can do that I might be missing, and I have booted it up with only one stick of RAM in, tried all my sticks in all the slots. Any help is appreciated, I am determined to fix this tonight.
