Pc reboots instantly while playing games

[astigafuguy]

hi ive recently bought a inno 3d gtx 760 replacing my old sapphire 4770, the 760 performed well and i was happy with its benchmarks and over all gaming experience until one incident when i played battlefield 3, as soon as the level loaded, after 5 seconds the pc suddenly rebooted, i thought it was just a bug or something, but then it happened again on second try. it also happened on all of the games i've tried ever since the incident happen, games like : Crysis 3, DMC, Black ops 2. ive checked my voltages from asus suite and they seem to be in normal readings. no over clock has been done what so ever. and when i try to run a benchmark on 3dmark firestrike it does the same thing as soon as a scene is loaded.

 

i need your help guys im still a noob

 

system specs:

OS - win7 64 bit

CPU - i7 2600k

Mobo - asus maximux IV genez/gen3

Gpu - inno3d gtx 760 ichill

Memory - gskill ripjaws 2x4 8gb

Psu - corsair tx750m

Sounds like either the graphics card or cpu are overheating. Do you have an extra graphics card you can put in their to test this? OR if all else fails maybe try to reinstall all the games.

Maybe the power supply is to blame and for whatever reason it can't handle the load when the graphics card demands more power. Even though it should be able to handle it perfectly fine it could be faulty.

If it's heat and it only takes 5 seconds the cooler must have come off or something, shouldn't die in only 5 seconds otherwise. More like faulty vRAM, if it's the video card that's causing the problem. It sure sounds like it would be the card as that's the most recently added component, but you never know.

 

First thing would really be to try with a different video card before troubleshooting anything else.

is the gpu connected correctly? wrong plug maybe?

hi guys, ive managed to borrow a msi gtx 760. i tried it and i thought it solved the problem. three to five minutes later... it rebooted again sadly

im kinda leaning on the PSU right now but still skeptical cause its still 6 months old. i've managed to run prime 95 and no reboots occured. as for temps im using an antec khuler 620 for the cpu, idle temps 39 - 40, load temps 50 - 60, considering the room temperature about 33-35 C. and as for the gpu, it has an aftermarket cooler so it never reaches 80C at full load, only like from 50-60C. is it a motherboard issue maybe? or ram?

It is PSU most likely, GTX 760 require ~100W more compared to 4770. It can also be driver problem (or windows), tho highly unlikely, but you can try with fresh install.

ok imma try fresh instal. and if hopefully i could borrow a psu and run some test on it.

[Najuno]

I've had something similar and my PSU was damaged. I thought as well in the beginning my GPU was the issue. But it turned out that the PSU had a failure. It was always just a clean reboot while I was gaming.

I tested my RAM, watched the heat and this is how I got on the PSU cause all my vents were spinning and the heat of all components was quite normal.

 

Try another PSU in your case.

i've managed to borrow a psu its an OCZ. and no more symptoms like reeboots. so i tried returning my psu to the distributor so that they could RMA it cause RMA here in the philippines is so dificult. but my main concern is that when they did a simillar stress test on the psu with almost the same components, no problems or symptoms where found. they also told me that they've been doing it for 3-days straight. so im beggining to wonder if its a psu problem or the distributor is just lying to me so that they wont spend a buck RMAing it to corsair.

[astigafuguy]

got a replaced corsair RM850w no more reeboots!

 

thanks guys!

 

 

Cheers!!
