Computer shutting down at random

[thraduil]

As the title says my computer shuts down at random. I have recently installed a few new parts
1. AMD FX 9590
2.Corsair H100i (checked for leaks and it wasn't the problem)
3. EVGA 770 GB ftw edition
My PSU is for 755 watts and i have a dual channel for RAM.
I think it may be overheating but after looking at CAM both my processor and GPU seems to run at less than 85 degrees Fahrenheit.
Just curious to see what i may be doing wrong ill attempt to get back as soon as possible. Thanks

what motherboard do you have?

i assume that is idle temp? gonna need a load temp like from gaming.

double check your temps with this http://openhardwaremonitor.org/

 

[thraduil]

roughly for the idle temp my processor never seems to jump more than 15 degrees or so. Most of the time that is the temp for games. The GPU when running the heaven benchmark got to maybe 90 degrees F. My MOBO is an: Asus Sabertooth 990fx r2. Ill run that program asap

this text file is the report i got

is your ram really running at 1333mhz mhz?

did you buy a xmp kit?

link the ram kit you bought and go into the bios and give me your voltage, timing and speed.

This would be the ram. I will have to check the bios when I get off of work. Before I went into work this morning I looked in the case and saw a third stick that I must of missed when I got the new ram a few weeks ago. However, my computer was running fine until the new processor was installed.
Thanks

its most likely your getting instability from your ram and the third stick not jiving with the vengeance kit.

put only your vengeance kit in the brown slots and go into the bios and set..

1.5v
1600mhz
10-10-10-27

any two particular slots or the darker brown ones? i seated them next to each other where i normally put them and put it up to 1600 mhz. I only got as far as the watch dogs intro movie like normal.
Thanks.

you have brown and black slots, use only the brown and you will be in proper dual channel.

so, it would be the second and fourth slot starting from the slot closest to the cpu.

still shutting down makes it quite a bit further.

 

[iron8orn]

ok.. now we got the ram figured out. is it only shutting down with the one game or just random?

 

[thraduil]

it seems to be only graphic intensive games. I was playing smite the other night and it was perfectly fine. However anything like farcry 3 or watch dogs doesnt last too long. I'm now thinking either psu which is a 3 year old 755 watt corsair supernova or maybe the heat again.

 

[iron8orn]

i cant find it online. you need at least 42 amps on your +12 volt rail.

its this one. Sorry i was thinking of another build

 

[iron8orn]

it has 4 12v rails and not a single 12v rail. When you have 4 separate 12v rails it pulls off of the same power inside the PSU box and seriously degrades the amount of watts through each rail..

im thinking you need a psu as i am seeing bad reviews for the model. get a 750w 80+bronze with a single +12 that has more than 42 amps and you may want like 850 to be safe for a oc and 1000 for sli.

you can run a graphics bechmark and see if it happens but if it has happened numerous times across many programs it will likely produce the same result.

 

[thraduil]

any psu's you'd recommend?

[thraduil]

I bought a new case and a new PSU and it worked perfectly! thank you so much for your time.

No problem, Come back to Tom's anytime you get stuck on something.
