Hi,

As soon as my system starts up, the temperature on my card hits 70-77 degs Celsius in which I've read around and found that this is normal for graphics. After launching and playing a game (League of Legends) for about 5-20 minutes, my screen hangs, and blacks out before returning to normal and having a popup on the taskbar telling me the graphics had crashed. After which, checking the temperature the temperature had hit the low 40s.

My card is about 1 year old. Is this an issue to worry about and why is this temperature change occuring?

Also, alongside with this, black squares were appearing on my screen, but a driver installation to the beta one rectified it. What was the issue? I've tried changing DVI cables but nothing seems to have worked. Is it related to the overheat issue, or is it due to age?

Thanks alot!

70-77C is NOT normal on startup. The symptoms you describe sound like that of a faulty card. Have you tried using it in a different system to see if the same thing happens??

I've not tried it on another system because I dont have another spare system to try. It's weird how it functions fine at this point, it's just the startup that gives the behaviour

That is very strange. Have you tried cleaning out the inside of your case, and the graphics card? Also, try to reseat the graphics card, completely delete all graphics drivers, and completely reinstall all graphics drivers.

Have done all as you mentioned inclusive of cleaning the fan, problem still exists at start up. I was wondering if it's a software issue because monitoring the temperature it slowly rises from 28 to about the 70 and stays there, but after the crash everything just drops.

Have you tried setting a fan curve? in a program such as MSI Afterburner, you can set the fans to spin up to a certain speed at a certain temperature. You're fan curve setup may be staying at a low RPM.

In attempting to change fan speeds the speeds will rise for a moment of 3 seconds before dropping to the default rate. I cant seem to make it change permanently

Strange...it may very well be a card gone bad. It's really impossible to tell unless you are able to put in another system to see if the problems persist.

I've tested with another card with two fans (GTX 560) and the idle temperature runs the same. This is extremely weird. No driver crashes for the GTX so far. Could it be a motherboard problem?

Either that, or a PSU. You could also try swapping out the RAM, or running Memtest86 to check if the RAM is bad. However, that is unlikely.

From checking event logs, the crash details are as follows:
Display driver amdkmdap stopped responding and has successfully recovered.

On further research a fresh install of Windows 7 seems to solve the issue. Is this really required?

You could probable do a "refresh", in which the installation disk will only replace windows files, leaving your data unaffected.

Did a full reset as opposed to your refresh, everything works fine now! Thanks for your help, nothing a little reformat cant do haha
