Hi , i have build new system couple weeks ago. While gaming (not every time) pc crashes and gpu fans stops spinning. i have to cut power off and power it on again to turn on pc. Apart from gpu all parts are new :
cpu: 4790k
mobo: maximus VII hero
ram: corsair vegeance pro
gpu: gigabyte hd 7850 2gb oc
psu: evga supernova g2 850w
i am new to pcs and i have no clue what to do :/.
Please help !!!
 
because one of my 7850's needs it at 20% or it will crash/lockup

it doesn't add any voltage it just raises the cards thermal limit

it might be pc memory or cpu voltage related idk but id start at the gpu power control first,then take things from there
 
Try defaulting any Overdrive settings you have, I found out my Card will hang/crash if I dare adjust memory clock by +1mhz.

I,ve changed power limit but it crashed again, this time fan was still spinning, i recorded temps with gpu-z and last one recorder was 64 c....is that too much?? or i have problem with some other componenet??
 
Do you have a spare decent power supply you can test in the system? May be the power supply is faulty, unlikely but could be a culprit
 
I had the same problem, I reformatted and updated the bios, I also remember buying a new PSU, 1 of those things fixed it! best of luck
 
i have run memtest , memory works perfect, i have only old ocz 500w psu at home. I have updated bios same day i build system, i google blue screen wizard but i cant find anything about software(by the way my screen turns off or have stripes when crash occurring) is there any software to monitor cpu?? is that could be related to ai suiteIII i use??? what software i can use to test cpu??
 
seems like gpu memory or core frequency crash (coloured lines down the screen)

what do you have the clocks set to?

and did it ever crash like that on your old pc?

still could be cpu memory controller voltage not enough but no idea on haswell what its called
 
when i bought this gpu after month just stopped working, for year It was collecting dust, aboutcouple month ago i have sent it for repair and with this pc i s firs time i using it. I just runned Prime 95 for 15 minuts and highest temp was 93c. I also noticed in ai suite that voltage dropping down; ill try to do some research on cpu voltage thing... GPU clock is 300mhz memory clock is 1200mhz I havent change anything.
 
memory clock should be 150 MHz at idle

id could be because its running 1200mhz all the time and overheating? load defaults in ccc and see if it drops

can test by setting the gpu memory clock to 1100mhz and see if it still crashes

ai suite can be innacurate,it used to throw up voltage warnigns on my z68 board yet it was fine

those cards aint power hungry anyway so doubt its psu

might be worth downloading display driver uninstaller and do a clean install of latest 14.7 beta amd display drivers
 
Screen going off too? gee, not seen that before seems more like a GPU problem now you mention that, Best advice is process of elimination, try without the GPU go straight from your mobo connection, this may seem stupid, check that the screws on your Mobo are not too tight causing ur system to short out, I have messaged my brother and he will send me the link for the blue screen wizard really nice software will tell you the reason it is shutting down basically
