Win 7 Freezes

Ok I got a blue screen but couldnm;t read it just now
I configured to not restart afterwards , I shall wait for the next to appear -.-;

REquested files attached.

Btw I got errors about disk reported by driver (11):
"The driver detected a controller error on \Device\Harddisk1\DR1."
"The driver detected a controller error on \Device\Harddisk1\DR2.
"Event id:11

And ofcourse this one:
"
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000008e (0xc0000005, 0x9645e2a7, 0xa3cab794, 0x00000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 121510-18298-01."
Event id:1001
(yesterday)

Dunno where today's blue screen was written it doesnt; seem to appear.

Ok some more information about my computer, I bought it around october.
The hardisk malfanctioned and caused system crushes , couldn;t (in most times) pass the mobo logo, so we replaced it (same company).

OS is not original.

And I was playing games using nprotect wihtout any problems on my OS, since october wihthout a single interruption (after we changed the disk that didn;t work before putting data on it).

I already formatted several times including full format (using win 7 disk and/or xp , I tried various things).

It once said something about voltage but I couldn;t read it passed too fast (it said so after unexpected restart...err one of the many -.-)...

It doens;t seem to crush when untouched-only while doing something, whether if it;s a game OR skype or anything from the user's end.

I just played a game that was not using nprotect gameguard, and got a crush...

After about 5 minutes of game play, again, out of the blue...
Then it restarted automatically and was stuck on "loading assus express gate" ,before the bios/mobo logo....

And ofcourse , running system reliability only says unexpected shutdown.
I am out of ideas....no norton installed, but no bluescreen, it doesn;t even realize something bad happened (other than unexpected shutdown).

Ok I was thinking about shutting my comp down and reseting the mobo.
I clicked start-> shutdown.

And guess what...another crush -.-, no game was previously activated.
Nothing was running not even the internet, nothing.

It was after a crush that I wanted to shut down my comp.

This crush had no sound loops, simply stopped functioning (mouse's light was turned off) keyboard stopped working, simply nothing.

So I resetted the comp again....

Ok I unplugged the graphic card (ati HD 5770) and am left iwth onboard (ati hd 4250).


And so far so good o.o.
