While gaming Hard Freeze / MSI R7950 Twin Frozr 3G

Why is my pc freezing up? It only happens while gaming in high graphics. Usually it freezes and causes a pretty annoying and loud buzzing noise. At that point it won't respond to any input. Turn it off and back on and good to go until the next time it feels like giving up... please help, I spent way too much on this pc and gpu to be dealing with this. :pff

  1. Is it pre OCed card or did you OC ypur card yourself? What is your psu brand and wattage? Can you check what is your gpu/cpu temp when your system freeze?
  2. I am a new bee to the whole pc jargin & lingo. gpu/cpu temps stay about 70-75 F while running heavy graphics. What is OCing a card? Is psu my cpu or my gpu?
  3. OC: overclocking.
    PSU: power supply unit
  4. psu=thermaltake 1000watt, overclocking is pre set on cpu thru motherboard bios options. OC on gpu on defaults through AMD catalyst control center it says its at: 960 MHz gpu clock, 1250 MHz memory clock with graphics overdrive enabled.
  5. so does your cpu running at stock setting right now or did you manually tinker with the mobo bios/uefi to overclock it? is this your gpu?

  6. That is my gpu. As for the cpu, there is an auto set choice between a few settings in my Asus Maximus ROG motherboard bios. I have it set to Gamer mode.
  7. Best answer
    from the spec the gpu from newegg the gpu suppose to have 880mhz of core clock. did you OC the card yourself to 960mhz or did it come like that out of the box? have you tried running your system using initial setting? so the freezing only happen when playing highly graphical intensive games? i have once having such problem but it is caused by my PSU not able to strong enough powering my gpu. but yours is 1000w unit so it should not be the case unless your PSU is faulty from the very beginning. if possible run your system on stock setting. try lowering the gpu clock to 880mhz as well and see what happen
  8. I will try unchecking the AMD Overdrive option that kicks it up to 960 Mhz. Thanks for your help.
