Q: The Blue Screen of Death..

Yeap, last night my PC went bluey and immediately restarts.. I'm not even sure what happened as I was browsing through the Youtube website.  

I can't make anything out of this so I hope maybe you guys know what could have happened to cause my system to 'fail'..

I worry it could be the CPU or GPU overheating.. I game quite a bit but not more 2-3 hours... It could also be PSU not supplying enough power.. 

I'm not sure though.. Help??



The attached DMP file is of the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e) bug check.

This indicates that a system thread generated an exception which the error handler did not catch.

BugCheck 1000007E, {ffffffffc0000005, fffff8800f4e683b, fffff8800553f228, fffff8800553ea80}

^^ The 1st parameter of the bug check is 0xc0000005 which indicates an access violation occurred:

3: kd> .exr 0xfffff8800553f228
ExceptionAddress: fffff8800f4e683b (atikmdag+0x00000000000c483b)
   ExceptionCode: c0000005 (Access violation)

^^ The violation occurred in atikmdag.sys which is the AMD/ATI video driver.


1. Ensure you have the latest video card drivers. If you are already on the latest video card drivers, uninstall and install a version or a few versions behind the latest to ensure it's not a latest driver only issue. If you have already experimented with the latest video card driver and many previous versions, please give the beta driver for your card a try.

2. Remove and replace avast! with Microsoft Security Essentials for temporary troubleshooting purposes as it's likely causing conflicts:

avast! removal -
