  1. It sounds like your card is over heating. What are you using to check your temps? I am not saying that your card is overheating it just sounds like it. On your power supply it is a ocz what is the model number?

    Do you have any friends to test your card on there computers or try another card on your computer? Try that if you have friends If not we will have to go from there.

    This red light shows the malfunctioning of your GPU so as DM186 stated it's good option to check with spare one GPU.first of all check your connection and ensure'bout proper power to the GPU.
  3. I had that problem when I first built my PC, I the power supply wattage was insufficient. Maybe your case is different, but you might be cutting it close with that power supply.
  4. if it is overheating and triggering fail safe protection.
    as its 4870 i would assume warranty long gone. I had video card given to me because it kept freezing. The problem was with old dried up thermal compound and slight loose heat sink attachment.
    After cleaning up and applying good paste, worked like new. that's easy fix,
    thou it also might be that your video card finally gave up its ghost.

    have you tried plugin monitor into different DVI port or HDMI?

    [#ff4300]now my two monitors work fine but don't know how long until the next no signal come in again still need help to fix these issue once for all [/#ff4300]
  6. About your power supply (PSU) it is a 500w OCZ what is the model number or letters like Modstream, Z series, ModXstream, Z t s, prostream, evostream, and gamestream. This will help pin point the PSU weather it is good or not. Here is link to MSI Afterburner it is free. You can monitor your temps from there.

    http://event.msi.com/vga/afterburner/download.htm

    If you are getting High temps it will be over 80c that is when you are gaming normal Temps should be in the 60c's idle temp should around 35c give or take a few. If it is your power supply then when it gets hot it will shut down power and will cause the problem you have stated.

    My question on your PSU does it's fan still work when you turn it on? If you are hearing noise coming from the PSU could be a sign that it is on it's way out.

    Your PSU is shot and you need to get another one. As for your temps it should at idel no games it should be around 35c at 54c tells me not good. But first think about another PSU. Here are a link or two for PSU's

  9. youe temps are normal for a hd4870. a reference hd4870 idles @55 and goes near to 90's at load. if you hear weird sound from ur psu u have to replace it now before it tears your rig apart. its your psu that causes the prob. its going to die soon
