Windows 7: My BSOD problems

Hi,
i have a lot of BSOD since 3 months. My computer is my own creation and was working great before. (i have flash BIOS in the past to solve graphic card comptability but thats all)

CPU= AMD Phenom II x4 955 Black Edition
Motherboard= Gigabyte GA-890GPA-UDH3 rev.2.1
Memory= Corsair XMS3 4GB (2x2GB) PC3-10666 DDR3-1333
Graphic card= Nvidia GeForce GTS450 (Gigabyte) GV-N450OC2-1GI (overclock)
Hard drive= Western Digital - Caviar Black 1To - 64MG
PSU= Corsair Pro HX650w CMPSU-650HX A

Monitor= LG 21,5" Flatron W2243T
Case= Cooler Master HAF-912
Keyboard= Microsoft wireless keyboard 3000 v.2.0
Mouse= Microsoft wireless mouse 5000

OS= Windows 7 Home Premium 64bit French (i buy a OEM version and install it)
-----------------------------------------------------------------------

2 days ago, i was forced to format everything and start over. I have use Gigabyte tool "DriverAgent.com" to be sure about my drivers...

Something got bad along installations (BSOD... impossible to start windows) and i have use "System retore" to solve problem.

Im now back before "GIGABYTE SATA2 Driver_1.17.59.0" and "Realtek High Definiton Audio Driver_6.0.1.6370" was install. Maybe they are the problem...

I have try Memtest86+ too, 7 pass then 11 pass, nothing wrong.

My Keyboard and mouse have been change a couple of months ago, i don't know if this is a possible threat with a OEM version of Windows...

Im not good in english, but please help! ;P

Here i put 2 events (happen before i use System restore)

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.



To ensure minidumps are enabled:

Go to Start, in the Search Box type: sysdm.cpl, press Enter.
Under the Advanced tab, click on the Startup and Recovery Settings... button.
Ensure that Automatically restart is unchecked.
Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
OK your way out.
Reboot if changes have been made.

Ok thanks!
Here the new repport and the minidump you ask :

I hope you will find the probs.

Lots of crash, new minidump since the changes you ask.

Can anybody give me a hint??

I have made the changes and send you the new minidumps, no idea at all? Now i got a blue screen even if i try to repair the system/restore with windows disc.
