Blue Screen Error(BSOD) for Vista with WORKER_THREAD_RETURNED_AT_BAD_IRQL

[pachhap]

Hi,
I am using TOSHIBA laptop with Windows Vista Home Premium Preinstalled. Configuration is as follows:
1. 1 Gb RAm
2. 110 Gb Hard Drive
3. Intel Centrino Duo
I am facing the issue of BSOD since i bought this laptop a month ago. I happen to find that this at any time gives us the Minidump files when it crashes with the blue screen put up at c:\windows\Minidump\Minidumpxx.dmp.
I installed the windbg tool to debug the Minidump files and found the following information.

And finding that, it can be the problem due to the buggy driver i enabled the verifier.exe on vista and restarted my laptop. It also crashed with a the Minidump with some information. I am not able to find or detect what is the reason for the crash or the BSOD. Please help me in that, I have attached the Minidump files with this thread, which has 2 Minidump files
1. Mini083107-01 ( Without verifier enabled)
2. Mini090107-01 ( With verifier enabled)

Any help in this regard will help me to solve the BSOD. Please help me out.

Thanks in advance.

Any help on this? Did anybody happen to experience the same and has come up with some solution on how to identify the faulty driver. I even carried out the Memory Diagnostic Test Yesterday, and the Hardware(RAM) is proper. The test yielded no errors.
Please help me out!

If you just bought it, I would take advantage of the warranty. That way problems are documented with it incase you have a lemon.

Thanks for the reply . The Laptop was bought some 4 months back and is still under the warranty period. Can you be more specific on what exactly you want to do with that, I didn't get "That way problems are documented with it incase you have a lemon" --->> What does that mean? Where will the problems documented ?
