In GTA and one of the half life games the games detail goes black.
I have a hd4850 on stock settings running at default settings on ati catalyst.
I am using 8.12 drivers and also had the problem using previous drivers.

The screenshot above gives you an idea of what it looks like, basically everything goes black with no color

HD4850
c2d e7200
2gb ram 800mhz geil black dragon
Windows XP SP3 i think it is
ATI 8.12

EDIT with more information provided here:
I put fan on 100% and temps were always under 68c according to gpu-z
HL2 @ low settings and performance under catylst 8.12

HL2 after i alt+tabbed to take the screenshot (Windows and glass etc was purple)

HL2 on high graphics and performance under catalyst (game crashed when changing graphics while game was live)

HL2 on high graphics and performance under catalyst (When i changed settings and restarted the game)

HL2 on high graphics and highest quality on catalyst

When i move throughout the map walls completely disapear and it makes it impossible to move as i cant see if im inside a room or outside. The textures also double up like it had been produced 5x and all stay on the screen

This problems has occured using 8.10 and 8.11 versions and the current 8.12 so i cant see it being a driver issue.
I have formatted using a clean install.
Everything on my pc is currently at stock and graphics card has never been overclocked

i figured that but my graphics card is on stock and players other games just fine, especially games like crysis on high details. My card hits around 100 but thats normal

Can i have some more opinons?
I got the graphics card a few months back off members market and recieved reciept and box etc. It was from overclockers - will i need to take it up with the manufacturers or could i do it with overclockers? This was months back and i had the problem when i first got the card but as it was only 1 game it didnt bother me until now its doing it with GTA

I would not want my gpu reaching 100. Download rivatuner and set the fan speed to 100% and see if you still get it. If not its probably a heat issue. If it is just heat then set up a reasonable fan profile that stops the gpu becoming so hot.

it only hits 100 when under full load and i tried putting my fan on 100% and everything on performance, it made no difference. Time to rma?
I also recall from when these card were first released they all hit upto 100c on stock coolers, my case is really cool aswell as my cpu etc
 
Yea they do run pretty hot but with a few fan profile changes they run pretty cool but if you tried 100% fan and you still had 100 degrees on the core it sounds like rma time. Have you tried a fresh install of windows could be a conflict in there somewhere if other games are running ok. Rma may take a while so i would do that first just to make sure as it won't take half as long as waiting on an rma. Like i say though if it still runs hot at 100 percent fan the card is a duffer.
 
Thats what i was thinking as other games run fine. Yes i can get it to about 80c but the fan noise is too loud and beside it automatically kicks in when it does get too hot and goes to 100%

I have reformatted windows and it didnt make a difference. I remember when playing half life it was random however, sometimes i would get wierd colors on my walls like purple instead of a normal color and then other times i wouldnt. This and the black marks were random, at first i thought it was my detail settings but it would randomly occur.

How long will an RMA take? i also remember my card stuttering under GRID but i think that was a general problem this was only under high detail however even though my fps was fine
 
Another thing you could try which solved a similar problem for me was turning catalyst ai up to advanced in the ccc. Phone overclockers first and see what they say about it. Rma services can vary a lot depending on the manufacturer so could take a month or maybe just a week all depending on how good the service is really.
 
Ok i updated the original post with screenshots of my problems in HL2 to better document the problem?

Answers: Can i RMA the card with these problems as my games such as COD4/UT3/CODWAW run just fine however HL2 and GTA4 dont

reading saphire rma service they say to contact the retailer which is overclockers so your advice?

EDIT* Fiddled with the catalyst ai aswell and it hadnt made a difference, off, advanced and standard
 
Give overclockers a phone and they shall give you instructions. I am not sure on how long its there responsibility or not but from past experience ocuk customer service is very good. Sounds like you have tried everything to sort the problem so its definately an rma card whether that be with ocuk or sapphire but try ocuk first.
 
ok thanks for your information, greatly appreciated! I will use the webmail as it costs 10p min on the phone and god knows how long i would be on hold. Not forgetting the fact my phone provider is a rip off lol
 
The first image from GTA looks like you've run out of video memory.

The purple thing with HL2 isn't unusual (known source engine bug) and it can happen on any card especially after alt+tab or changing video settings.

Not sure whats happening on the screenshots were you can see through walls but that doesn't look like a hardware issue - but rather a software/driver problem.

here is another image outside
http://e.imagehost.org/view/0860/outside

I actually posted the screenshot above another by accident but if you look at the top you can see what i mean about the crazy effect where everything multiplies 5x and you cant distinguish anything, loads of different graphical errors happen as you move about

And how could i correc the video memory, the settings were fine and that was the first part of the game and first part of benching

I cant see it being a software issue when i have formatted and it happens with multiple drivers
 
I dont get it, i just run GTA4 now and theres no problems? Any ideas people?

I tried restarting and changing from performance and and balanced and high quality and it still plays fine.

It fixed when i changed the graphics from high to low but now that i put them back to high its fine again?

What are your thoughts? i dont want to send the card back and have them return it to me because it worked fine :(

i contacted overclockers and they told me to contact the person who sold me the graphics card. Even though the person give me a copy of the reciept and box etc. Is this normal procedure?
 
I think it might have something to do with the catalyst ai but when changing things i cant get 100% results
Just fiddling there when i tried to put higher graphics thats when the black marks start to appear, even though its in the green and only using 400 / 500 MB or memory.

Think the memory could be on its way out or?
