Hi guys. So straight to the point. I bought a new system 2 weeks ago, the cpu was overclocked by the company from 3.0 to 3.45, everything fine until I bought Battlefield 3 and it is crashing to the desktop with a error message:
When this happens my graphics go all "glitchy" with strange blanked squares and horizontal lines across the screen and colours all over the place. All my applications start to crash at the same time like ie and chrome so only a restart fixes it.
I tried all other know bf3 fixes but nothing works. I ran prime95 and done 2-3 tests. The in-line large gave an error "Rounding was 0.5, expected less than 0.4" and I noticed core 3 was not seeing activity while 1,2&4 where 100% usage. During this time I also noticed the same "glitchy" interface in apps.
I ran the blend test also but it was fine for 30 mins or so with all cores at 100%. My core temps do not exceed 40c in any test.
Then I tried another "in-place" test but I got a blue screen crash which read:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 2057
Additional information about the problem:

Files that help describe the problem:
Mainboard : ASRock N68C-S UCC
Chipset : (Family 10h) Athlon/Opteron/Sempron/Turion HyperTransport
Processor : AMD Athlon II X4 640 @ 3000MHz (OC'ed to 3450)
PSU: Corsair CX 500w (v2)
Physical Memory : 4096MB (1 x 4096 DDR3-SDRAM )
Video Card : NVIDIA GeForce GTX 460 v2 (1GB)
Hard Disk : Seagate ST350041 8AS SCSI Disk Device (500GB)
Operating System : Windows 7 Ultimate Professional Media Center 6.01.7601 Service Pack 1 (64-bit)
Nvidia Driver: 285.79
So I am thinking of down-clocking a little, reset to default 3.0Ghz or upping the voltage to get it stable but I have never done it and have no idea how the guy who built it did it either, I am thinking through the BIOS.
I think the gpu is fine, its a Palit GTX 460 v2, stock overclocked at 778mhz. I am wondering where I would get the flash bios for it? Its running the latest nvidia drivers but I cant find any flash for the palit 460v2 at all.
Can anyone tell me how to reset my cpu to stock speeds?
Great news!!!!!, I set the clock speeds back to 3.0GHz and the crashing stopped! Now that I know thats what causes it I think ill set it back to 3.4 and turn up my voltage to around 1.4-1.45 to see if i can get it stable without temps going to high =)
