Test the graphics card in a known good system. However, there is a third component you have not mentioned which may well have failed; your power supply.
In order for us to provide better assistance, please post the make and model of your system components including motherboard, memory, processor, power supply and graphics. If yours is an OEM build (such as Dell or Acer), post the make/model of the computer and that of any non-stock upgrades or modifications.
PS: On a cold startup, does the system POST? ie do you get any display or beeps whatsoever? Do any fans or lights turn on?
I don't have access to a known good system unforunteately.
Ok now I am worried. Now the pc is turning on for a few seconds then turning off then turning back on.
There is no beeping and no screen or post screen at all.The case fans all turn on. The motherboard lights turn on (2 red,2 green). The Cpu Fan doesn't turn on.
It started of yesterday when the pc would boot up then freeze. I got it started and it worked all day and last night. Then the monitor wouldn't show anything but the pc was working and I could access my network to my desktop (Pc with no monitor) today by the laptop. Now it has the problem with it turning off after a few seconds!
