ATI Radeon HD 5750 crashing help

Right so when playing games my pc freezes sometimes the screen goes black sometimes white sometimes beige with vertical lines filling the screen.

I can sometimes get it unfrozen by ctrl-alt-del and go to task manager and shut down the game but most times I have to manually turn it of via the power switch.

The freezes happen when playing a various selection of games, examples include GTA4, Race Driver: Grid, cod4, cod6, F1 2010, Dirt 2 and crysis 2.

My pc has no problems running anything else like iTunes and video converters etc just when gaming.

I can rule out most problems people think it might be:

-it cant be the power supply as my brother has exactly the same power supply and is running a more powerful graphics card (5770) with no problems what so ever.
-it cant be a dodge board as I have changed boards from a micro atx to a normal atx designed for ATI cards
-it cant be the processor as I have changed from a Intel pentium E5200 to a Q6600 and have cooled both with an Arctic Cooling Freezer 7 Pro Rev 2 heat sink
-I doubt its getting to hot as I have changed from a £30 case to an antec 900 2 gaming case with 6 fans installed (high quality fans)
-I used to use a 9400GT and had no problems with it but it lacked power for performance gaming so upgraded it to the 5750

Im thinking its a problem with the card and was wondering if anyone know's why it does this

Thanks in advance

Do you have the latest driver installed from AMD?

Downloads

I did a reinstall of windows a couple of weeks ago and installed new drivers then plus this has happened on older drivers (when they were new) but will install most up to date drivers now

Sounds like it is artefacting. Download Techpowerup's GPU-z and run the stress test on it. If the stress test shows artefacts, it is likely your card is dead.

do you recomend any programs to use to stress test or is there a feature in GPU-Z that im not seeing

plus I don't want to sound like a noob but what is artefacting

Make sure you are using the Download TechPowerUp GPU-Z v0.5.3 | techPowerUp
There will be a stress testing feature on there.

Artefacting is where you get screen errors, such as a few yellow triangles in your picture. These are a sign that the card cannot hand the load on it.

< chuckles> sorry can't help it when i saw Gilligan's pic i started to picture the skipper screamming gilligan !


Ok to be serious about the hd 5750 did you oc the card and the power connectors tight and not loose also how long have you had it ? is there a possible chance to take it back and exchange

@ Lordbob75 this is a screen shot of its stats under a stress test the temp is the thing that alarmed me

@Solarstarshines I haven't OC'ed it, brought it new about 6 months ago and not sure they will let me take it back now

You need to take the stress test on there and watch it for about 30 minutes to check for artefacting (it will tell you if there are errors).
70C is not too high for a GPU, though it is a bit toasty.
