Systems with integrated graphics are just not meant for serious gaming -- and therein lies the problem I think.
Is this a notebook, by the way? They are usually designed to run hot >>

Check the bottom and underside for clogged vents -- blow them out with some compressed air. Consider a notebook cooler -- though I don't really place much confidence in them from personal experience.
You have received a blue screen with dumpcheck data, so let's do this:
1 > create a new folder on the desktop and call it "dumpcheck" or whatever you like
2 > navigate to
%systemroot%\minidump and copy the last few minidump files to that folder.%systemroot% is normally c:\windows. They are numbered by date. You can paste that address in address bar to get there.
3 > close the folder and right click on it and select
Send to Compressed (zipped) Folder.
4 > use the "manage attachments" in the "advanced" reply window to upload that zip file here as an attachment.
This might point us to a non-system driver causing the error, if one exists for it.
