Computer randomly freezing

[schopra12]

Hey there,
My computer has been randomly freezing and it happens maybe once a day or every two days and its really frustrating. If I wait long enough after the freeze, the screen goes black and gives the error nvidia driver has stopped responding and successfully recovered.

I have tried using DDU, updating Windows 10 etc and to no prevail. I really dont know if its my GPU thats faulty but it seems to run perfectly fine with all games at max settings and it idles at around 30c and under load maxes at 65-70c.

And the freeze is fixed by doing a manual reboot, but then after maybe another day or so, the freeze will just randomly happen.

Computer specs:
GPU: EVGA GeForce GTX 970 ACX 2.0
CPU: Intel iCore i5 6600
SSD: Samsung 850 Pro Series 128GB
Power Supply: Corsair CS750M Modular 80 Plus
HDD: Seagate 2TB Barracuda
RAM: Corsair Vengeance LPX CMK16GX4M2A2133C13 16GB (2x8GB) DDR4 Black
Motherboard: Gigabyte GA-H170-Gaming 3 Motherboard

Any help would be awesome.

Thanks

Do you have a friend that will let you try their PSU or a shop that will test yours?

Hi schopra12 A stress test may reveal the culprit.

Download AIDA64 and HWMonitor and put them on your desktop side by side.
Run the stress test in AIDA64 on the CPU and FPU for 10 mins. Taka screen shots at 10min mark and post the results.
Keep an eye on your thermals and stop testing if temps reach 80C.
I would like to see your Rail voltages for 12v, 5v and 3.3v in HWMonitor during test.

You can also do a separate test on your GPU and also DIMMs.

Here is the screenshot after test for 10 min

The stress test has revealed the culprit schopra12.

All rail voltages are below acceptable range, especially 12v at 0.048. You will have to have it tested under load or swap the unit out with a known working unit at same or higher Wattage to be absolutely shore. however, i'm 99% that is your problem. CPU seams to be OK.
If still under Warranty then RMA the unit. Explain to Corsair your findings. They are pretty good with Warranty issues. If you can get a gold certified unit that would be even better.

Does that mean that the power supply isnt providing enough power?

 

[MeanMachine41]

That is correct. Your test indicates the PSU is not performing as it should under load.

That is correct. Your test indicates the PSU is not performing as it should under load.

Is there a way I can fix this without getting a new PSU or is a new PSU necessary? Also, could you tell me what the normal rail voltages should be?

Thanks

Edit: Oh and this PSU was gold certified if that makes a difference.

You can do damage to your system with a failing PSU.

Voltage Rail Tolerance Minimum Voltage Maximum Voltage
+12VDC ± 5% +11.400 VDC +12.600 VDC
+5VSB ± 5% +4.750 VDC +5.250 VDC
+3.3VDC ± 5% +3.135 VDC +3.465 VDC

Ok thanks,
This is how my PC is looking normally.

So in terms of HW monitor, how much V should there be for 3.3v, 5v, 12v etc

Yes iv'e seen the pic and as you can see for yourself your Rail voltages are way down.
Voltages should be as close to there spec as possible and within +/- 5%. max.

Ok I just checked voltages in BIOS and 3.3v is 3.63 V, 5v is 5.1 V and 12v is 12.024v

Is this alright?

 

[Martell1977]

The issue isn't how the PSU looks while idle, it under load that the PSU fails. When you push the PSU, it fails to deliver the proper voltages and the GPU freezes or crashes.

The 80+ Gold rating does not mean quality, it refers to the efficiency expected of the unit under load. There are some poorly built units with a decent looking rating.

Here is a good reference for PSU's:
http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

As mentioned, if the unit is under warranty, RMA it, otherwise, try to get a new one from EVGA(ignore their B1, W1 and P1 units) or Seasonic and 500w should be plenty for your setup.

Ok, I just compared some stas (using HWInfo) with my brothers PC (same GPU and PSU) and its pretty much the same but his GPU Power is around 19-20W and mine is 14W. Also, I tested the PC under load aith AIDA extreme and the rail voltages stay at 12.024, 5.1 and 3.364v. I dont think we can rely on HWMonitor's voltage readings as they're giving the same whacky ones in my brothers PC.

What does this mean?
