What graphics card are you using?

What card is it? I had a heap of trouble with the Sapphire HD7970 vapor-x and it required a bios flash to perform correctly with litecoin.

Have you stress tested your card to see if it isnt just CGMiner?

Try OCCT

i reduced intensity to 10 but still had same issue. I am at loss about this...

card is not overclocked.

There is  no bin file in cgminer folder. i use cgminer for bitcoin mining and that works fine, problem only  happen with litecoin mining and i am using scrypt version of cgminer.

I used ati utility to clean the drivers and loaded 13.1, my windows 2012 get  bluescreen upon boot so i had to revert back to 13.4. I use windows 2012 as my base workstation OS, not running any server type thing just find it more stable than windows 8.

i lowered thread concurrency to 8192 but still had same issue.

Thank You for replying, i will try this right now and report back

thread concurrency is too high.
Also on 13.4 cgminer can't create .bin for some reason on my rigs, 13.1 works, check if there are *.bin files in your cgminer folder to confirm.

Is the card overclocked?

Try disabling the DWM (Destop Window Manager Service) I hear that some people crash with it on (i personally do not mine LTC)
However the error Clearly states that its Allegedly your video drivers crashing/overloading/restarting/rebooting, Have you tried reducing the inensity? Try some default settings or a lower overclock (LTC uses memclock)

hi, everytime i try to litecoin mine with cgminer (GPU mining for litecoin) i get following error in cgminer.exe. i have tried cleaning my ati drivers and then reinstalling again 13.4 driver but still get same error, short of reinstalling my OS. Help please.
