Nothing is overclocked.
My screen keeps scrambling whenever I start up games, and then continues to sketch out even after I exit from them. At first, it even persisted after I restarted and shut down. Then I went inside and tightened things up, and checked all the connections. After this, it started up normally, but would continue to sramble if I tried playing any games (ie nhl 2006, WoW)
If I change the resolution after it starts scrambling, it fixes itself, until I try to play a game again.
I went into my Catalyst Control centre, and the little car preview was scrambling. I can see polygons and vertical lines of fuzziness.
I downloaded the latest ATI drivers, and uninstalled the old ones. When I went to restart the computer, everything was scrambling.... even my BIOS.
I installed the new drivers, and restarted, but nothing changed....
I got fed up and just shut it down and did a couple Sudoku's to cool down....
I started it up a couple of hours later and everything seemed fine...
I didn't try any games or anything, because I've got a big assignment due tonight, and I don't want it to be screwed up when I try to do that...
I'm using the latest drivers from ATI/Omega for my Radeon 9700pro, I only experience visual artifacts like that when the card overheats.. which I'm assuming that your 9800 is.. try opening your case, and direct some airflow(like a fan) onto your video card, and see if it changes anything.
If you don't see them afterwards then you have an overheating situation.
It's weird... I've had these settings consistent for the longest time, it just seems that in the last week everything is screwing up!
My fans are working fine now..... AMD Cool N Quiet seems to have fixed it... I'm monitoring it and heat with SpeedFan though.
As for the video card.... It was sketching out all last night and this morning. At first I could play WoW for a while, but then if I minimized the game, it would sketch out, then do a VPU recover, and things would be normal. After a couple times of this though, it began to scramble even after the VPU recover.... and then even during restart. All this morning I got the same results, where no matter how long I let it cool down with the power off, it would always start up with everything scrambled.
However, just on some kind of whim, I unplugged the SATA drive (just has TV episodes on it), and everything seems 100% OK now.
I'm thinking maybe the vid card wasn't getting sufficient power supplied to it maybe? I'd also been having some random HD crash errors....
Think my PSU is screwing up? It's got 420W output (I forget what it is... but it didn't come cheap, and wasn't stock)
