I have just changed out my PSU, MOBO, RAM, and Case. Only thing to change out is the CPU but I know that it works because it worked in another PC that I have so i know it works. I tried upgrading the RAM and installing a PCI USB adapter card and i got som yellow and black pixellation on my monitor. Shut the computer down, removed the card and no video. with old MoBo. Removed and reseated several times the old and new RAM. Fans still spin and the HDD is still spinning up. Got new MoBo, same out come, no video. Have tried this on 4 different monitor with different ( VGA, DVI, and HDMI) still no video. Have removed components to trace problem and when I get to the CPU, Still no video, Post or Beeps. Like I said CPU works fine in my other computer. and other computer's CPU will have the same out come as before.
