I bought most of the below spec from OCUK about 3 months ago, with that I also purchsed an addional 460 786mb to go with my one a bough a year or so ago also from OCUK.
It was all working great, until today, I was playing Arma II with a friend and my entire PC locked up. I rebooted, went into the game fine and then 10 mins later, same thing, game just froze and I had to power down.
When powering up, my PC would get to the windows 7 loading screen, then the monitor would turn off (no signal) and reboot this would loop continuiously.
So I rebooted in Safemode, reinstalled drivers (did this 3 times with different drivers incase of compatability problems with Beta drivers).
Managed to get into windows 7, went to SLi profiles, was on single card mode. As soon as i switched to Sli, PC would freeze and reset.
I tried swapping the cards about (the new card was in the secondary slot, and I put it in the primary slot and I couldnt even get into windows).
I am at a loss really now of what to do, the card is only 3 months old, but it was a refurb with a 1 year warranty, what worries me is, doesnt appear this is in stock now so if it has died or the prev owner had issues, can i still get a like for like replacement as 1gb card wont work in Sli.
Any advice would be welcome, has anyone had exp of returning things in warranty? a real PITA as my gaming exp with those cards was brilliant and SWTOR is just around the corner
Oh and the card still appears in windows, still powered up, fan still turning, no bad smells, no visible damage.
