Problems with AC IV and CoD Ghosts, PC Reboots

[linsyschopman]

Oke my specs to begin with:

intel i7-3770k
GTX 660
Asus Z77 sabertooth
16GB Ram
750W Bronze certified PSU

Oke, so I already ruled out overheating.
CPU full load 35-45C
GPU Full load 60-70
Tested memory, came out fine.
Tried a different PSU problems were still there.

Now the problem itself:

The PC Reboots in-game with Ghosts on certain settings and with ACIV when i'm in Havana.
No BSOD, Just a reboot, no weird noises or anything.

Help me out please, i have no idea what the problem can be anymore?

I do NOT have this problem while benchmarking with for example Prime95, Furmark, Heaven etc.

Checked the event log : Critical error 41: Kernel power

I was getting reboots on certain games. Then it started getting worse (sometimes while watching 1080p movies). Replaced the power supply and the problem went away. I wasn't "under powering" the system, just that the PS was going out (less than a year old, too).

Can you provide more information about your power supplies, brand, model number, number of amps on the +12V rail. Do you have either your CPU or GPU overclocked, if so try returning them to stock clocks and see if the problem persists. When you do benchmarks, do you run Prime95 and Furmark simultaneously? You need to be stressing both your GPU and CPU in order to determine if your PSU can deliver enough power, just testing one at a time won't cut it. Heaven also doesn't use that much CPU horsepower, especially compared to newer games so it might not be the best indicator of system stability as far as the PSU is concerned.

i am benchmarking them both at the same time. i can't really find out my PSU brand and model because i need to get it out of the case again which i can't do at the moment sorry. i'm upgrading my GPU pretty soon, if problems persists i'll replace the PSU
