Different BSOD messages when gaming (WoW, Diablo3, Borderlands 2 etc.)

Hello.

I have been getting alot of different BSODS when playing games for some time now, it's very annoying because i won't have the chance to play for more than 15-30 minutes if i'm lucky.

I attached a zip file with the dumpfiles.

Some of the different BSODS that I get are for example:

Page Fault in Non Paged Area
System Service Exception

Some the files that seem to have caused these BSODs are:

dxgmms1.sys
nvlddmkm.sys
ntokrnl.exe mostly but also the ones below some times.

ntfs.sys
portcls.sys ...etc.

Nothing happens when i browse the internet or watch movies etc. It only occurs when playing games. Also don't ask me about trying safe mode because I can't play games in safe mode -.-

Thanks in advance for any help!

Look for an update on your BIOS version. The current one is too old!
