  1. You aren't able to update your drivers? That's odd.

    What other problems have you had with the card? Are you sure it's the card that's causing them?

    Do you have any other problems installing software?

    What are your full system specs, including power supply wattage and amperage on the 12v rail(s)?

    Also, open Catalyst Control Center and go to ATI Overdrive and unlock the card if you haven't done that. Some programs (like Afterburner) you have to go to the config file and enable unofficial overclocking to get it past CCC settings... but first it should still allow some speed tweaking.
