It doesn't look like you currently have any minidumps. Could you please check C:\Windows
, zip and upload it using the method from your previous post. Since your have re-formatted the hard drive a few times, the issue may be hardware related. You may have a faulty video card, hard drive/RAM.
-Have you tried re-seating the video card?
-Have you run any hard drive or memory diagnostics??
You can run Seatools (Hard drive diagnostic) here
(memory diragnostics) to test your hardware.
These tools require being burnt as an image to a CD. And be booted to on startup.
Please post if you are unsure how to do any of this.
