  1. Hi, Is there a case speaker (beeper) connected to the motherboard?
  2. did you use compressed air? Those contain liquids which might have damaged something.
  3. alexoiu: Yes there is. mobo does give 3 long beeps without RAM
    angaddev: Yes I did, it's pure air designed for components specifically I use it at work all the time.
  4. Then maybe it's something wrong with the graphics card. Can you test with a different one?
  5. Went out and bought GT210... still nothing
  6. It's not good buying parts if you're not sure they're faulty. Maybe testing the PC at a local shop is a better option.
