Hey there, so as the topic says I'm getting vertical lines in my games, in some games they appear more as small boxes though they still go upwards in a line. This has only started happening since I reformatted my PC about two weeks ago and since then it's been getting worse and worse.

My PC stats are.

Motherboard: ASUS M4A89GTD

Processor: AMD Phenom(tm) II X6 1055T Processor 2.80 GHz

Ram:4GB

OS : Windows 7 Service pack 1 64-bit.

Graphics Driver: 12.6 (before the format it was also 12.6 and it had no problems.)

Graphic Temps Idle
GPU Temp: 61 C
GPU Temp (DISPIO) 51.5 C
GPU Temp (MEMIO) 65.5 C
GPU Temp (SHADERCORE) 56 C

Graphic Temps Running SWTOR
GPU Temp: 77 C
GPU Temp (DISPIO) 92 C
GPU Temp (MEMIO) 92 C
GPU Temp (SHADERCORE) 89 C

Thanks in advance to anyone offering help and I'll provide whatever additional details are needed if asked for them.

It seems like a dead card to me. Try it in another computer.

It may be that your HD 4850 is beginning to fail.

Graphic Temps Running SWTOR
GPU Temp: 77 C
GPU Temp (DISPIO) 92 C
GPU Temp (MEMIO) 92 C
GPU Temp (SHADERCORE) 89 C

92*C is quite hot. I have never seen my reference design, isngle slot HD 4850 run that hot....ever.

When was the last time you cleaned the card from the dust build up? 92*C...

I'm not talking about just cleaning the outside of the card. I mean inside the fan and heatsink assembly (cooling fin array).

Have a look:

I concur, not even my 5970 runs that hot in games, even when clocked up to 5870 speeds, and it doesn't take a heck of a lot of dust in the very tight quarters of a GPU heatsink to elevate temps, although I suspect after 4 years the TIM is dried up on the GPU and the thermal tape/pads is/are not doing its/their job either. Another thing is your PSU, which we don't know what it is yet, if it isn't sufficient it will cause problems. Finally it can be the drivers, try going back to 12.1.

Ok I'd previously tried downgrading to 12.5 and 12.4 but they didn't change a thing. Downgrading to 12.1 though has made the lines vanish. I'm going to keep an eye on the card temp though, as I agree it does run quite high even though I noted down the (DISPIO) when SWTOR wrong. It was running at 77 C not 92 C. Only the MEMIO was running at 92 C. As for cleaning it, I'm hesitant to take the card apart so I'm leaving that for if the lines return. As for how old my card is, I only brought it last year.

 

Edit: Ok after an hour's play, the lines returned in full force, I checked the GPU temp and it was sitting pretty at around 74 C.

Are vertical lines the only kind of artifact you're seeing?  Temperatures in the high 70s are still pretty toasty, but artifacts caused by heat are usually more... random.  Polygons stretched out by misplaced vertices, weird off-color pixels that flicker in and out, and missing/disorted textures are all common when there's too much heat.  If it's always only vertical lines though, then that makes me think of a driver bug, or something else more repeatable than weirdness from too much heat.

Those temps are indeed hot, but perfectly fine for single slot 4850, and far from what can cause real damage. As far as I know the GT is a single slot version of the 4850. I still suggest trying it in another computer.

So I did a bit of experimenting, I left the game running with the vertical lines when they appeared and about 10 minutes later a hell of a lot more artifacts appeared, from flickering HP bars to screen tearing. Closing the game revealed that it had also affected everything outside the game as well and had left large mutlicolored horizontal lines across the decktop. Rebooting removed the lines and I then lowered the graphics settings on the game to see how long it would last on the lower setting. On the lower setting it encountered no problems at all and the graphics problem didn't appear, which makes me think it is without a doubt a heat problem.

So I've gone and brought myself a new card. It's a shame that only after one year with this, until now, excellent card (I mean it was still ranked as 7.4 on window's system check) I've had to get another one but it seems like this is the only solution. Thanks again everyone for your help with this.

It's a 4 year old card with something like 60 different components which are subject to extreme swings in temperatures on a daily basis, so it wouldn't take much for a solder joint to come loose or a memory chip to develop a bad address range. You could have tried to bake it in the oven before you went out and bought a new one, then again the HD 4000 series is legacy so it was time to move to supported hardware, like a HD 6770

If we had system specs as per the STICKY thread, then we could probably pinpoint things better - could eliminate PSU if a good brand or say "Hey, those drivers & that game = bad, try ... " etc. Did it ever get cleaned within that year of usage - could be overheating .. Did you ever replace the thermal paste to eliminate that as an issue etc etc etc etc ?? ?? ??

Mind you, upgrading to a non-legacy card was a good idea anyhow .. even if you think the WEI as a "great" benchmark & think 7.4 actually means something
