Radeon XFX Core Edition 6670 display driver stopped working but has restarted

Intermittent flickers just running windows. Lock ups and hangs with the driver stop / restart error when gaming on various games.

Recently purchased this graphics card. I've had this system for several years do you think my issues are likely PSU related? Here is my build:

  1. Is it overclocked? Thats the only thing i can think of. I get that sometimes on my OC'ed gpu and my friends when i was testing his.
  2. Could be the PSU. Could be a dying graphics' card.

    Could be something more esoteric. I assume you've tried a clean install of your drivers?
  3. 480w should be plenty of power - assuming it isn't a junk PSU.
    I have a XFX Radeon 6670 and it works fine for me.
    Note that stopped responding is different then stopped working

    What driver version are you using?
  4. Option 1) Bad PSU
    Option 2) Unstable Overclock
    Option 3) Overheating

    Option 3) Overheating

    1) possible - the system is 5 years old; though I volt meter checked a free power connector and got 12v and 5v
    2) using default settings
    3) the card is only about a week old - I will monitor the temp for a few days.
    4) driver version is up to date: ver -- I will give a clean install a try.
  6. Try underclocking.
  7. Your PSU is too old and taking capacitor ageing into account, it might not be able to deliver the required amount of power to feed the extra GPU, change PSU asap, even though it may not solve the problem, i recommend you change it before you BLOW it up

    Tried underclocking and the whole system went wiggy. Screen went black multiple times for several seconds, funky lines etc... Went back to default settings after this.

    Also did a clean install and still had driver stop and restart errors when running Halo combat evolved. Funny thing is that I don't seem to have any issues when running Diablo 3.

    The graphics card is a pci e 2.1 while the mobo slot is pci e 2.0. With this being a 5 yr old system perhaps a bios update is in order. I'll probably grab a new PSU first and see how things go.
  9. Have you resolved this issue. I have the exact same problem. Changed PSUs too but problem occurred again.
