BSOD crashing on desktop/playing HL:S and on system repair

Hey guys,

I recently got my first crash(0x00000050) on my pretty new Asus G74SX-A1 laptop while playing Half-Life: Source and never had any other blue screens before that. After that, I restarted and went to desktop and it eventually crashed again but when it did I opened Steam(not sure if connected). After that second crash, I went and scanned my PC on safe mode and then restarted again and tried to do a system repair but right after it was done I got the second BSOD(0x0000001a).

I have not recently installed any new hardware or anything that could change my system in any way. The last time I updated my PC's hardware was when I updated my graphics card (Nvidia gtx 560m) to a beta client about 3-4 weeks ago and haven't had any problems.

I looked through some of the error dumps my self to see what was causing the problems and it says it was "ntoskrnl.exe+7f1c0" but I'm not too sure what to do.

I provided the dump files in the attachements(2 dump files zipped).


Edit:
I think I might have fixed it by updating my graphics card, performing hard drive error checking, and chkdsk /f. I am not totally sure if it is resolved yet and if it is not, I will post back with more information informing that it has not worked.

If you guys have any more ideas or know what is actually wrong, you can always inform me with a reply!

Since you have sorted it, we'll keep fingers crossed and hope they won't come again!
