Playing Game (HoN) Screens go Black, needs hard reset. Only gaming

Hi People,

I built my own PC and its been running great for 2 years.

Using an SSD for OS and boot, and 1TB black drive for games and programs.

I recently installed "Heroes of Newerth" for some giggles. I dont believe it is a highly intensive game on the GPU but i get some crazy crashes on my pc.

Pretty much Ill be running HoN and Skype and both screens just go black, no sound or beeps, no error, nothing.

My keyboard nad mouse lights are still on.

My keyboard has multiple user levels, (4) each have different colour lights, but none of the user levels work, which makes me think the driver is not running on that, so maybe the pc has 'mostly' crashed.??

Ive done a SMART test and all good
Done a memory test (windows) and 100%, no errors found.

Aside from this i dont know what the next step is.

Usually i solve these on my own, but since there is no error I can't even google tog et something more sepcific!

ideas anyone?

Thanks for any advice or suggestions,

Gangel

have you looked in event logs at the time of the crash to see if thats showing anything , id be 99% its your gpu driver crashing

Hi Archie, thanks for the response.

There are a few errors but i dont know what ids important.

Errors:
Event Log 6008
DistributedCOM 10016
AppModel-Runtime 69

Critical:
Kernel-Power 41 Task (63)

The distributed Com one was before it ccrashed this morning when i was not home!

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {D63B10C5-BB46-4990-A94F-E40B9D520160}
and APPID
{9CA88EE3-ACB7-47C8-AFC4-AB702511C276}
to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

This occured when comp was doing nothing, just had firefox open, but no gaming. i was out of the house and i found it "black screened" when i got home after work!
