I just hooked up a brand new build and i cant even get into the bios because when i start it up i get 3 red lights on the back of my HD Radeon 4870, The monitor works fine on my other computer and all my other cpus are old so they have intergrated graphics so i cant test, the psu is 550W, rosewill. Please halp
The lights indicate certain error messages. All of the lights will flash at post indicating the card has passed its self test. One light each for the power plugs being loose, one light for a temperature fault, and another indication (a fourth light or all of them on at once) indicating a critical core power fault.
If the lights stay on either the PSU is not powerful enough/broken, or the card is faulty.
