BSoD, new computer, 0x0000001a and 0x00000019

I have recently built a computer running Windows 7 Home Premium 64bit and after a few days of use, began to receive BSoD's with the error code 0x0000001a. I have tried replacing the hard drive and PSU, to no avail. The motherboard was also sent back to be replaced, not helping either. I have spent a while browsing the forum, however have found nothing useful to my problem. Also, I began receiving the 0x00000019 error. Attached are the files from the SF Diag Tool. I am unsure as to whether it includes information on both BSoD, I will try and get a hold of the other necessary files if they are not attached now. Thanks.

Another BSoD. 0x0000001a. If it's any help, it occurred just before I was going to install a game from a disk, Unreal Tournament 3.

Sorry, I meant just after installation began.

Hello.
I have had 1 BSoD since I last posted, it's another 0x000001a. I have updated the graphics driver, I believe it's called Catalyst. I have removed all of the Asus software from it. I believe the most recent BSoD was identical to the one before it, however I can post that one up if it helps.

I have shut down my computer normally since the last BSoD, I'm not sure if this affects the dump. I ran the SF Diagnostic Tool 5 minutes ago, with the attached file being the output.
