New Pre-Built Cyberpower Desktop PC Crashing

[Viper344]

I bought a gaming PC recently and when I started playing some games on it (Farcry 4, Fallout 4, Farcry 3 Blood Dragon, Call of Duty: Advanced Warfare) it would crash at differing times depending on the game. Farcry and Fallout I can play for a good amount of time, usually around 2-3 hours. Call of Duty and Blood Dragon however would barely last 30 minutes... if that.

The crashes completely freeze up the computer. Nothing responds, no ctrl+alt+del, no alt+tab, nothing. There is a usually a loud buzzing sound that accompanies the crash and the only way to bring it back is to hit the reset button. It has even started happening when I leave the computer alone for about 5-15 minutes alt-tabbed out of games.

I had posted another thread and the general consensus was that it might be a Power Supply Issue but I really don't know and am starting to get pretty frustrated with this.

Current set-up:
Mobo: GA-78LMT-USB3 6.0
CPU: FX-8320
GPU: NVIDIA GeForce GTX970
PSU: HPL-800BR-F14S (C) 800watts

I have ran Prime95 (20 minutes), Furmark (30 minutes), Windows Memory Diagnostic and it never happened.

I have been running CPUID HWmonitor in the background for quite some time now and trying to monitor the heat buildup. Here is what it looks like after playing Fallout 4 for about 20-30 minutes.

It's probably the power supply. They always put low quality ones in those things.

Yep never get the default or cyberpowers own brand of psu. Really though you specified the parts why would you ever put a shit power supply in a gaming machine. I mean if you ordered all the parts your self and put it together then who would you have to blame.

I didn't specify the parts. It was a bundle, I guess pre-built wasn't the best choice of words. I thought I had done good research but I am not an expert with hardware.

All good not trying to be mean but a lot of people build one of the systems on their site and then get good quality components then skimp on the psu and wonder why they have issues theres a ton of write up about folks doing this then trying to blame the company I mean if you build it through them they will use what ever parts you pick. In your case though if you bought it preconfigured as a package I would suggest getting a tier 1 or tier 2 power supply for it then you should have a decent system
