Sapphire hd 6950 2mb crashes after it's detected

Hi there,

Just got the Radeon HD 6950 2mb dirt 3 edition

I uninstalled old drivers, shut down, put new card in, started up computer, began installing the drivers from the CD - and the screen went black halfway through installation, and stayed that way.

I restarted - screen goes black just after the windows logo comes up.

I put the old card back in, started up - it started fine. I then tried installing the latest Radeon drivers (11.11) with the old card in, shutting down, and putting the new card in.

This time it started up fine - card worked great, played skyrim for 2 hours, then it crashed. I'd try to start skyrim again and it crashed every time.

I unistalled drivers - put old card back - skyrim works fine.

I tried to install the new card again, removed old drivers, shut down, new card in. Now as soon as the hardware wizard detects the card, the monitor goes blank. I can't even try installing different drivers.

Is this a faulty card? Any advice gratefully received.

  1. not a faulty card, your cpu bottlenecking your card heavily mean your cpu is not too strong to feed a 6950 that's why you getting blank screen.
    2nd look at your ram speed it's only 400mhz you should have approximately 800mhz or higher.
    Overall your system can't able to handle high end card.
  2. I Disgree With The Man Above On The CPU But Not The RAM - I Have A Friend Running A Athlon X2 @ 3.0GHz And A GTX470, But You Do Need More And Faster RAM Get It While Its Still Cheap, Its Probably A Compatibilty Problem Stemming From XP It About Time You Update Your OS, XP Is Old News That Machine Still Has Alot Of Petential But Not If Your Outdated OS is Holding You Back.
  3. So what exactly do I need to do - how do I update my os and give it more RAM?
  4. upgrade your cpu and ram
    cpu must a higher model like c2d e8600 or better quad core
    ram must be 800mhz frequency.
  5. Ok - I basically have to upgrade nearly everything to use this video card.

    Can you recommend a good graphics card that would run on the setup I have?
