Error Reading Problem

ok so i can be playing a game and all the sudden my computer will restart with no warning and when come back on i get error report saying this is the problem....

c:\DOCUME~1HP_ADM~1\LOCALS~1\Temp\WERf6df.dir00\Mini110207-01.dmp
c:\DOCUME~1HP_ADM~1\LOCALS~1\Temp\WERf6df.dir00\sysdata.xml

what is this and what do i do plz help

 

The files are created when a "blue screen of death" error occurs. Look in C:\Windows\Minidump for files that have a DMP extension. Zip 4 or 5 recent ones and attach the ZIP or RAR file here. We can run a debug utility to find what caused the problem.

(If you don't find the files in the above location, look in c:\DOCUME~1HP_ADM~1\LOCALS~1\Temp\WERf6df.dir00)

 

k i got it in the first location

 

The logs show a problem with "ati3duag.dll" (a library file which is part of your ATI graphics card drivers) while playing Half Life (HL2.exe).

Many Google results seem to suggest reinstalling the graphics card drivers (or a differnet version) may solve the problem. However, if it only happens in Half Life, maybe some graphics options in Half Life.

 

well actually it only has happened while playing potal and team fortress2 half life 2

 

Sorry, I meant Half Life 2.
