i build my pc around 6months ago and all has been fine. last night whilst browsing the screen flickered, went black and the suddenly the pc powered down. I wasnt sure what to make of it so I turned it back on. It booted fine and lasted 30 minutes before doing the same.
This morning i turned it on to come to hard ocp to find posts related to this found a few involving black screens. I then put the pc in hibernate mode nad left for work. Now tonight when i come back and try to boot up the monitor is not picking up a signal but the pc sounds like its alive and there are no beeps at all. Checked leads between pc and monitor - fine. Checked the monitor works by pluggin in a old laptop and its fine. I opened up the box and noticed that the video card fan is not moving at all plus there was a bit of dust on the fan and grills of the cards heat sink. Cleaned it up but still no lifesigns.
I havnt overclocked the system and i made sure to get a good psu based on this forums users recs.
its an antec eathwatts 650w.
the card is a saphire 4870 512mb.
motherboard asus p5q pro
q6600 cpu with ninja cooling tower.
I dont have any spare cards or psus to find the fault source but i do have an unused multimeter, can i use that somehow to narrow down the source of the problem?? does anyone know whats going on here? is there warranty support with video cards? any help will really be appreciated!.
