I would pester them to death about this system. From reading your posts, I gather that the trouble did not just start recently, rather it likely started day 1 after you initially booted up (or problems began at that time that ultimately led to the NVIDIA BSODs).
NVIDIA writes some of the finest drivers in the world; we rarely see them in BSODs as compared to ATI video drivers, which are definitely problematic. My estimate of the ratio for BSODs caused by NVIDIA drivers vs. those caused by ATI drivers - 1:100 - meaning that we may find one NVIDIA driver issue (almost always out-dated drivers) vs. 100 ATI driver issues.
The fact that your system is BSOD'ing and naming NVIDIA tells me that there is a hardware problem afoot. I do not believe at all that there are any problems with the current NVIDIA drivers. Your system's problem is more than likely unknown hardware failure.
If you paid by credit card, contact the credit card company and try to have the charge stopped/reversed. Doing so will certainly get AVADirect's attention and force them to deal with you.
You deserve a new system, considering that you likely began to have problems with this system very early on after receiving it.
Just to review - 4 BSODs - Bugchecks -

0x1c7 - store component detected a corruption in its data structures; probable cause "NT" - the Windows Kernel - a default of sorts
0x113 - Microsoft DirectX graphics kernel subsystem has detected a violation
0x50 - invalid memory referenced; illegal page fault
When you return the system, include a printed copy of this thread to show them what crash experts have found in their system.
