I need some assistance please.
My computer had the following:
AMD PhenomII x6 1090t @3.2 GHz
HD5850 xfx Black Edition Clock speed 765MHz
2x2GB DDR3 RAM (Corsair xms3 1333MHz)
Gigabyte 890fxa ud5 motherboard
Hitachi Deskstar 3TB 7K3000 SATA III Hard Drive
Corsair TX650W psu
and I've just added another 2x2GB DDR3 RAM (Corsair xms3 1333MHz) and another HD5850 xfx 725MHz.
I had the 5850s running with crossfire and at first it worked well. I ran a benchmark in unigine engine with good FPS and a good score. I played a couple of levels of Bad Company 2 and it also worked well. I had high frame rate and it ran very smoothly. It was definately and improvement on the single card.
Every game/benchmark I have run since then (games include crysis, need for speed hot pursuit, plants vs zombies) has resulted in the whole computer freezing, except for the sound which carries on, and requiring the use of the reset button or shutting down with the power button. This usually happens within 5 minutes and seems to be happening quicker and quicker each time. It is also preceded by flickering images coming onto the screen for a split second (I'm not sure what the term for this is).
At first I assumed that my PSU wasn't able to provide enough power for my new setup but I've found other people online who have the same problem I have with similar components and an 850W PSU from a good brand.
I've tested the new card on it's own (with the old card installed but disabled) and I get the same problem which makes me think it's a problem with that card rather than a crossifre problem. I've also taken the new card out and reseated it in the PCI-E 2.0x 16 slot and moved the old card from the PCI-E 2.0 x8 to the x16 slot.
I've also connected the new card directly to the PSU's PCI-E connectors and used the molex adaptors on my old card.
After the last time it froze and I turned off the computer, I didn't get a display from any of the DVI outputs on either of my monitors.
I would like to know how I can tell whether I've been sold a faulty GPU, whether I've damaged it or whether it is conflicting with the rest of my system. Is it possible that the new RAM is causing the computer to freeze?
This has been causing me a lot of stress since I got the new graphics card and I don't know what to do.
