I just got this card and when changing DX9 to DX10 on Far Cry 2 it crashes when loading to menu and i have to force reboot, and it can't even get to the menu on Oblivion without freezing right when the menu sounds go on. even sometimes when rebooting and accessing the catalyst control and pressing the "3D" menu the computer would freeze.
At one point while playing Crysis it crashed and gave me a BSOD, which fixed itself saying the "ATI graphic driver crashed" so i clean installed the 9.4 drivers and same problems are happening. it also isn't overheating because the temps staying at like 57 to 60's.
is the card a fluke, or is there something i'm doing wrong? any help would be appreciated
oh and my specs are e8400 @ 3.0, sunbeam 580w, 8gigs ddr2, vista home 64bit
I had similar problems. I reinstalled OS and downloaded the 9.4 suite and it seems to be fine now. Its much more stable than before. Also, try installing just the driver instead of the whole suite. Still no go, try an RMA. Could be just a bad card. Maybe its not getting enough power - a pre-built computer generally has little power to spare.
i downloaded driver sweeper cleaned out everything ati and nvidia and still same problem, so i reformated got rid of nvidia chipset drivers and installed 9.4 and still same problems. i'm gonna assume its the card and try getting a replacement
One problem I see is the PSU, as pointed out by Orangegator. That Sunbeam 580wt may be just too small to power the 4890. I'd look to a larger, good quality, PSU with a minimum of 650wt.
A problem with Cyberpower, and a few other companies, is that they will stick an inadequate PSU in as standard and the unknowing customer will buy it without realizing that the PSU needs to be upgraded to actually run. Oh, it might turn on, but once any load, such as a game, occurs, the computer will crash. I think this might be happening in your case. The Sunbeam is right on the line concerning power and it gives up when anything more is demanded of it. So if you take it back to Cyberpower, ask about having a larger PSU installed.
