[Solved] 4890 producing Artifacts.

For some reason my XFX HD-489A-ZDFC Radeon HD 4890 at factory settings artifacts after a restart. It never starts (or has yet to start) artifacting when the computer is on. Even from temperatures ~88 C from a GPU stability test. It only seems to do it after I restart and turn it back on immediately.

At first, my solution to the artifacting was to pull down my removable motherboard tray and it seemed to fix it. Though, it didn't always solve the artifacting. I was thinking that the GPU was somehow was bending the motherboard when it had its flat side facing the bottom of the case even though everything is mounted correctly.

Just minutes ago I drew a more plausible diagnosis. Every time I restart the system after being on load from a test, it would produce artifacts. I haven't tested this when the motherboard tray is down. After I wait a while, it would start up with no artifacts.. So maybe it has to do from heat? Though it would not artifact from higher temperatures (88C) at which it was subjected to during GPU stability tests. I restarted at ~73C.

There have been times when the computer told me that it can't display the screen on the monitor. Sometimes it would be pure static lines.

So I'm wondering what's wrong with the card and what should I do with it? Should I RMA it? Or will they (NewEgg) even take it. It has been less than 30 days since I have bought it.

Thanks for replying. The artifacts show up everywhere. Less noticeable in windows but you can see some "twitches" in the screen sometimes. There were dots on the bootscreen. Sometimes it shows nothing when I boot but white with red and green static lines.

Forgive me but I'm not sure what I understand by display configuration or natural pixel matrix size. I didn't change much in CCC except setting AA and AF to max. My display is currently an old Dell 14'' that only supports up to 1024x768 resolution. I probably won't be getting a new monitor till around Black Friday.

Edit: Sometimes the text in the bootscreen would be jumbled up.

Have your card replaced. If it persist look at your LCD display. I have seen older generation LCDS having odd issues with new generation cards.
