ATI GPU degradation... or mobo/PSU failure?

Main issue - graphics driver crashing when 5850M overclocked.
When i bought my M15x i was able to use 920/1200/1.15V for benches and 870/1200/1.1V - for everyday use.
5-4 mounth ago my max clock's was changed, cos previous was not stable... New one is 840/1200/1.1V and sometimes 900/1200/1.15V.
Now i can't even normaly boot up when GPU overclocked. 625/1000 more or less stable, any another bigger clock's will crash videodriver.
Sometimes even Aero crashes videodriver.

Changing driver version wount help. OS reinstalling - same.
Average temp while gaming/benching was 80-85C.

 

Just like a car, it's components will wear out much faster if you drive with higher revs, until components start to fail and then you realise i should drive more carefully but the damage has been already been done.

You're GPU is getting tierd as it's generally known OC reduces components lifespan. In future consider either reflowing gpu or buying new one.

 

Yep, sometime it should happen.
II just wanna know... it is just dying GPU, or it can be dying mobo & PSU?

If i will buy newone videocard, and notebook wont work properly... It will be sucks...

 

Is the system fully stable at stock clocks? Stress the GPU and the CPU and if its stable then it is the OC that's making it unstable.

 

i would stress the cpu to see if its still stable, are any other components on the m15x crapping out? im pretty sure its just your gpu dying, i would run gpu benchmarks to stress the gpu and not furmark.....

 

I would try running it on stock clocks. If it shows the same then the problem might definitely be the GPU. BTW, maybe you should just use the stock clocks to avoid this to happen again in the future.

 

Look's like CPU and memory is ok.
Sometimes can pass 3dmark11 at stock clock's.

But even downclocking didnt prevent video driver crashing and BSOD's...
