Hi, I am totally new here even though I tom's hardware has helped me a lot on many occasions.
My HUGE problem now is that I have upgraded my Alienware (and for all the trolls out there I know its way overpriced) and added 2x SLI GTX680. The problem that I get is just randomly my pc freezes and reboots or sometimes just freezes with a buzzing sound and i have to manually reboot it.
I have done few things to exclude some scenarios:
Changed:
1)Changed all the fans
2) CPU from i7 920 to i72600k
3)Motherboard : alienware r1 to r3
4)PC - toatally new alienware
now my system is: 3960x 3.3GHz 16GB ram Win7 64bit 2xGTX680 3xBENQ XL2420T Surround display PSU 875W
I have done the mem test and passed
I have loaded the temp up with graphics and fine
what i did notice is on evga precision if i put the power target to 176% the crashes are less
should i change the power supply???maybe go for 1000W or 1200W even though everyone seems to think the 875W should be fine?
