Computer restarting at random times when playing games

[bonguuu]

Hello and good evening,

My Computer restarts randomly and without warning when playing games.
This can occur once a month or more often.
I get no BSOD, it just shuts down (Like I would pull out the switch just straight up no power) and then it restarts after about 3 seconds...


Temps are fine 30-45°C CPU and GPU
Tested RAM with memtest for 8 hours straight, nothing :S

SPECS:

CPU: i7 3770K
GPU: Nvidia GTX 680 (OC'd by default)
PSU:LC power silent giant 650W
RAM: 2x4gb Corsair XMS
SSD: 128gb Agility OCZ 3 Series
HDD: 3TB Seagate
Intel Core i7-3770K Sockel 1155^
Gigabyte GA-Z77


I attached my PSU and GPU with pics

I would also like to note than my CPU jumps to 4GHz in the task manager while its just set to 3,5Ghz as far as I know

I see that your video card is the OC (overclocked) version. Companies like that take the chipset from Nvidia, overclock it to what they think is stable, and then slap it in a package and tell you how much faster it is than the competition. They just don't up the voltage. I had that problem on my stock OC'd video card too and was able to fix it with MSI Afterburner. Here are my suggestions:

Download MSI Afterburner.
Underclock it to the standard 1006 MHz (Standard setting for that chip - I think that's about 65MHz less than what it's set to)
Test it out on a game.
If it still restarts, bump up the voltage a little bit at a time. I went up to 37 mV before mine was stable.

Or try a new PSU, never heard of LC, and I doubt it`s enough for that card.

LC6650GP3 V2.3: LC - POWER

Looks like it only needs a 550W. 680 GTX specifications

You believe what you want, I'm sure the OP of this week old thread has fixed his issue, thanks for your input and have a great day.

 

[Think Tank]

Yes, I tend to believe the specs from manufacturer. And you can't be sure he's fixed his issue. Have a great day!

I smell PSU failure as well. LC power is trashy brand that lies about the wattage of their PSUs.

PSU's degrade over time and if it's mediocre at best NEW....

Standard things if a system is crashing frequently, just in general:

Check all the case fans (for dirt and grime slowing them down TOO) and clean or replace, it's a cheap part treat them as disposables.

Make sure the heatsink is still connected to the CPU [plus thermal paste doesn't work FOREVER, keep this in mind, because it should be between the heatsink and your CPU, and the heatsink and your GPU (on-board or seperate card)].

Uninstall/reinstall ALL the critical drivers: Talking video/audio/chipset + Direct-X itself.

Reseat and/or test the RAM.... see Tutorials on testing RAM procedures.

Make sure your surge protector you are using isn't shot. [You are using a surge protector, right?]

HEAT is the enemy and parts wear out, if the manufacturer's warranty on a PSU is.... that's ALL you should expect with normal use and if it's always on... that's not normal use any more, and so shorter life expectancy.

Your motherboard is the most vulnerable with so many parts, they can go USELESS any time.
