Unknown problem

My brother's gaming computer has begun kicking him back to desktop when he games. He plays primarily WWII On-Line and WoW. This is the error he receives:

AppName:exploror.exe
AppVer:6.0.2900.2180
ModName:exploror.exe
ModVer:6.0.2900.2180
Offset:0000b1eb

He has updated and run his AV software, AVG I think, as well as AdAware and SpyBot to no avail. I suggested he run HijackThis and the below is his log. No idea if anything in it is even close to related to his problem but thought better to ask and not find anything than not ask at all . Thanks in advance for the help.
