Heat lvls are staying within range of what they are suppose to be, but I do get lucky.. I have two harddrives and have already saved everything worth saving to the other in case this was an option. I will give that a shot as well. I decided to go ahead and upgrade graphics anyhow so a new card is on its way. Guess I will know if it was the cards as soon as I get the new one hooked up. I did have an issue one day where my brother decided.. to run two high end games at once x.x i didnt catch him in time for the mistake, skyrim and final fantasy xiv where both on at once, thats when one card gave up at once and I had sli off at the time.. so i took the first card out and swapped places with the secondary card and kept sli off, it has worked since but this is my main reason i think its the card. I think it was too much for either of them and they got burnt out bc of that. The second card to least amount of damage and is now finally catching up and dying. I run off of phenom IIs quad processor AMD 8gig ram 2,000 GIG memory 2 HDDrives. and of course the two sli gts 250s. I just bought a new PSU for the 2 gtx 460s i have on the way. Hopefully its my cards and nothing more will have to be done, otherwise i have saved everything worth while on my second drive and will reinstall windows 7 on my main. Honestly when i had this pc built for me i knew even less about them than i did now and i do think he has them overclocked in bios. though im not sure anymore its been just over a year. I will look at that as well. Thanks guys!!
