Random purple polygons

I'm running a 3 ghz P4 on an ecs 915p-a motherboard with a msi 6600 gt. After I load the game, everything seems fine. However, after a few minutes of playing, purple artifacts/polygons will start to appear randomly on the terrain. They show up and disappear almost instantaneously. Green ones also appear in the grass. Sometimes the armor/equipment I have on when I look at my inventory look like a bunch of squares also. Does anyone know what's wrong? I have all the quality settings at max. I lowered them to see if that's the problem, but it didn't help. Any help is appreciated.

is it overclocked or maybe overheating?

the description sounds like visual artifacts from a card under stress

Nothing in my system is overclocked.

It's artifacts. Doesn't have to be overclocked for it to be overheating. I recommend lowering the temperature on your radiator, opening the window, or just plainly opening the case of your PC.

That or get a case fan.

Or check your settings and make sure that it's on "High Quality" instead of anything lower. The simplest way to do this is if you have the tray icon. Click once on it, then go to Performance & Quality>Image Settings>High Quality

One quick note on case fans - there are two things involved, positive air, and negative air.

I'm not sure which way round they are, but basicall, i think positive air is in, and negative air is out, of the case.

It's a good idea to blow air in to a PC, so that the air is circulating, true. But that air needs to come out, or it will over heat faster. Usually, it's a good idea to have a little more negative air, than positive.

More out than in. But not to much. (or the in air has no effect)

if you have anything that is over heating, the software that came with it should be able to detect so. Check around any software you may have, see what you can dig up.

Also a quick note, not sure how familiar you are with your Vid Card and it's core. But i've always been a huge proponent of removing the stock cooler, and scraping off the coolant paste. Then buying something like arctic silver or another silver cooling paste, spreading it and replacing the stock cooler. It's a simple operation, just have to be gentle with your card. If you want detailed instructions PM me.

It's called Intake and exhaust.

Front = intake fans (air going in) (could also put fans on the side panel)

rear = exhaust. (Air going out) (could also put fans on top of case, since hot air goes up.

And yes, more exhaust is better, since heat will build up, and air NEEDS to be flushed out. Otherwise, that air will get trapped and build up even more heat.

It's also called positive and negative air, on the grounds that negative *which is the outflow, i looked it up* air inside a case is better.

erm... I'll see if I can find an article...

gotta love google:

Please see my post about "my PNY 6600 gt is overheating" here:

In a nutshell, once I removed the side of my case, the graphic probs in GW have stopped completely.

It's artifacts and they're usually caused by overheating.

Still a good thing that he asked, some manufacturers overclock them right when they come from the factory.

Thats not overheating, that's tearing.

You have a card issue, try lowering the graphics and see if it goes away...

Random stuff like that can be hat, but the artifacts described sound more like a physical issue. I had a 9500 Pro hardmod card that was that way. Turned out one of the BGA RAM modules wasn't seated properly. It never ran right.

What's your AA set at? I know in some games if I turn up my AA too high ingame I end up with a bit of purple around.
