PC shuts down while gaming

Specs: win 7 64 bit, AMD fx6300/8gb ddr3 1600mhz
Hi,it's the third time my pc shut down while in game. I dont know why. I looked in the system logs where after all shutdwons i just have gap where nothing registered and an error that last shut down was not proper so no help there. It shut down and wont power back on unless i unplug it for a few seconds,no blue screen no nothing. It happened first while playing tomb raider and then crysis 3 and today while plating Call of duty advanced warfare. What i have noticed today because i played without headphones that during cutscenes in game the fans slow down. In all games im close to thermal limit (r9 290 directcu 2 ) and looking back all shutdowns war during or just after a cutscene. Is it possible that after a cutscene the still quite hot going back under load suddenly thinks it's overheating and shuts everything off completely without warning ? Is that possible ? It's not the power supply im within power limits i can stress test all the parts at once and have no issue.

Sounds like it's down to heat. I assume you have made sure it is clean inside (including fans, vents and all heat sinks). Are you overclocking by any chance?

Let us have the make and model number of your computer and in particular your graphics card.

Always pop back and let us know the outcome - thanks

"It's not the power supply im within power limits"

Post the make/model & specs of your PSU & let us be the judge. Are you still using the Raidmax RX-500 that you previously posted about?

I got a sentey ERP750-SM 750W power supply before buying an Asus AMD r9 290 OC direct cu 2 edition video card. I only overclocked the cpu but that is managed whatever i do never goes above 70* celsius and on the gpu only the factory OC to 1ghz on which i do not dare doing more because it's reeeealy close to throttling.

What stress test should i do to stress everithing at once maybe i can replicate the issue ?

Maybe it does so at odd times when you're not looking.

The Extreme Rock Power SM series is made by Super Flower for Sentey. Unfortunately it's not 80% certified but it is a good quality unit.

"I only overclocked the cpu but that is managed whatever i do never goes above 70* celsius"

How much did you overclock? Over 4.5GHz? If not, your temp under load shouldn't exceed 60C. And if it's a milder overclock than that, your load temp should be closer to 50C. If your temp is close to 70C, either your heatsink is clogged, it isn't installed correctly, or it's undersized for your CPU. See the following, especially the last entry:

The cpu is f---ing fine it's overclocked to 4,5 at 1,4 core voltage and it never ever goes abouve 65 even with the hot gpu quite close to it. It's dust free the paste is applied properly. My PC just shut down 3 times while gaming since i bought the new GPU which is throtling or realy close tot throttling. I explained how it happens.

I would try underclocking the factory OC graphics card a little bit and then testing. If it does not shut down then the card has too much OC, not enough cooling, or there is not enough (or proper) air flow through the case to remove excess heat. If you indicate how many fans, where they are, and the orientation (Intake/Exhaust) of each, we may see a pattern that might help. Sometimes it is too many fans rather than not enough fans that causes eddies in the air flow and instead of removing all of the heat, it traps some of it in certain areas. The best is to have the cool air come in low in the front of the case, move over all components, and exit high in the rear of the case. Side fans disrupt this smooth flow and sometimes even unusual CPU fan orientations contribute to this as well.

You have to be a little bit crazy to keep you from going insane.

Hi,im back with no results. After a while i ran prime 95 and at 4,5 ghz it was an unstable overclock so i thought that was what caused the shutdowns. I am back at stock speed. Itțs winter now i have no problem with overheating anymore. CPU st stock barely reaches 55 celsius.Changed the thermal paste on the GPU which made wonders 10 degrees cooler and than i underclocked it to factori setings. I even dropped the speed of the ram because it only ran at 1600 with 1.65 volts. So everithing is stoc nothing is overheating yet i still have a shutdown with no warning or apparent reason. As i said windows doesent tell me s--- no blue screen no nothing just a hard shutdown in games. I have to unplug it from the wall until all the power is drained and than only plug it back in to turn it on. If i dont unplug it wont turn back on. I am out of ideas. What i would like to try is either another r9 290 to test under load or a better power supply. Im theory the power supply should be fine but even the manufacturer website says 78% peak efficiency which should be enough but i take that with a grain of salt. It is beyond me. What i never got an answer to is. Does computers shut down when they reach power limit like that or they just slow down ?

Have you looked in Event Viewer to see if anything shows up at the exact time it shuts down? If not take a look next time. Note that it's not unusual to find errors reported (often down to minor program bugs), so only concern yourself with anything that matches the date/time.

Always pop back and let us know the outcome - thanks

I think that at this point the issue is probably either the power supply or the graphics card. Either the power supply is not the quality to consistently deliver the current your system including graphics card demands during gaming or there is a flaw in the graphics card. Since you have to unplug (or switch off) the power supply completely to restart I lean strongly towards the power supply, possibly a self resetting circuit breaker or power filtering circuit that needs to be powered down completely to reset after being overloaded (possibly the fault is in that circuit and is tripping prematurely). I would try a different, better quality power supply 80% or better efficiency, single high amperage 12Volt rail, Active PFC, and a long 3 to 5 year warranty.
