Only when playing BF3 my comp restarts

[notrust81]

I've tried couple of things here
Deleted Nvidia HD Audi driver
Disabled Upnp and SSDP services
Reinstalled BF3 and Origin
Updated Punkbuster
Reinstalled some Nvidia Drivers, 290,36 seems to be the most stable one
(i tried running 285,62 WHQL, 290,53, 295,51, 295,73 WHQL, i used Driver Sweeper everytime for clean install.)

I use the following bench, ( my comp didnt restarted here)
prime95, Blend mode, for 4hours
memtest
3dmark11 and furmark
i used hwmonitor for temps, my cpu was max 72C and my gpu 68C

I run these games without any problems
Rage
Skyrim
Deus EX

My specs
q6600 G0 at 3.60ghz
DDR3 8gb 1600mhz, default settings (KHX1600C9D3T1K2/8GX)
MSI p45 Diamond, ( MS-7516 v1.0) motherboard
Coolermaster Realpower 520
Asus ENGTX570 DCII/2DIS/1280MD5

The game, BF3, makes my comp restart randomly, it happened after 15 min, after 4 hours, even longer then that.
It also happens on different game mode, maps and max players.

I hope you guys can help me with this, its really frustrating

i think your psu is not enough for your computer and when you are using both (cpu + graphics you are going over the real cpu wattage what is causing the system to shut down.

Hello,
if this is what you got: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171009

it looks like that's not enough for your system

http://support.asus.com/powersupply.aspx Asus PSU calc

with 1 hdd, 1dwdrw, 3 usb and 2 fans comes out to 600W. Typically I'd take that and divide by 0.9 to give you some efficiency margin. So, I'd go with at least 650W

just to make sure, check your even viewer for any information, if it's anything besides PSU there should be logs

I agree 100% with Anti and richard. When you calculate the efficiency of your PSU with the Overclock you have going, when BF3 uses a certain % of your GPU/CPU your computer does not have enough power and BOOM blue screen. Looks like thats probably the culprit.

Thx guys, today i found a program to test my power supply, it stressed both cpu and gpu. And after 13 min it gave an error, that was caused by the power supply.

So i've got another question, im thinking about upgrading to two ENGTX570 in SLI and maybe a i5 2500K (which if needed i will overclock it to the max on air).

Should i buy a power supply for this system or can i buy one already for my future system. What is enough power for this, is 1000W ok??

 

[ricardois]

no need for such power 1000W is for 3-way sli systems, 750w is enough for 570 sli, but the thing is that you can't just buy any 750w psu, you must look for a good brand, generic brands sometimes are much underpowered psus and cant get even close to the wattage labeled on the psu;

unless you are thinking in overclocking gpus and cpus you will not need more than that.

here you see a nvidia certified PSUS list:

this is more than enough for your system.
