4890 / COD:4 Issue

So, I've finally decided to reach out for help. I just built my new pc about 3 weeks ago, while playing COD:4 every once in a while I get a random game freeze it locks the screen and freezes on a sound (repeating over and over) CTRL+ALT+DEL doens't work so a hard reboot is needed. Every time I get this random lockup I get a message in my Computer System Log states as follows:

I tried upgrading to the latest catalyst, but while playing COD I get this REALLLLLY annoying almost glitchy type walking when graphics get even a remote heavy, i feel like I'm walking / running in a strobe light, ....|......|.......| instead of |||||||||||| if you know what I mean.

Memory OCZ Platinum 6GB (3x2GB) DDR3 1600

Thanks for your help/suggestions.

  1. Did you follow the recomended way of upgrading the driver, meaning first removing it from add/remove programs, then remove any folders and installation files and then restart before you start installing the new driver?

    Remember this issue from my Radeon 1900xtx x 2 (cf) but thats a while back...
  2. Is the card overclocked?
  3. Start with the obvious:
    Check Task Manager for any processes that are taking a lot of CPU time.
    Reinstall the video drivers from a fresh download and do not use Beta or third party drivers, just the 9.5s from ATI.
    Undo any BIOS changes and overclocking.
    Make sure Windows is fully updated.
    Make sure you have the latest version of DX, it does not update automatically with Windows.
    Make sure you have correctly installed the motherboard drivers, sometimes they should be installed in a certain order.
    Check the card is correctly connected: Those connectors may feel fully in, but they may not be making full contact.
    Use GPUZ to check the card temperatures and Speedfan to check the CPU.
  4. The stuttering is lag. Lag is caused by a number a things. Network traffic, Number of players in the same direct vinicinty of you character, number of graphic extras that are happening.

    You should try turning the settings down to a bare minimum first and then turn them up one by one and see what causes an issue. The computer you have should run COD 4 balls out as mine is ancient compared to yours and runs it very well.

    The other issue you mentioned was a lock up on sound loop. I have had this happen before and an update to my sound driver worked.


  5. there was an issue with realtek drivers and cod4 as far as i remember!

    first thing to do is update them. i'd say its almost certainly them, if cod4 is the only game this happens in.
