Computer restarts after a few hours of mining

[zeukin]

I was previously mining with 2x gtx 560 ti's and I mined constantly with them for two days no problem and then a few days ago I come home to my computer being restarted. I realized it's time to buy a new, better card and save up to get a whole new rig dedicated to mining. I bought the r9 980x and yesterday it was mining for 5 hours straight, the temperature was at a stable 77C and this morning my computer had restarted again. Could this be a video card problem or something else? I'll post my computer specs.

Motherboard: x58a-gd45 MSI
PSU:Corsair HX850W
CPU: i7 960
video card: GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X 3GB 384-bit GDDR5 PCI Express 3.0 HDCP Ready Video Card
OS: Windows 7

What piece of hardware could it be that's overheating in the mining process other than a video card?

---------------------------------------------------------------------------------


I'm checking my temps right now and the only hardware that has risen in temperature is my video card up to 75C which is not enough to cause a restart imo.

May sound simple, but make sure windows updates, is not set to install at a specific time.  Set it to download, but you choose when to install.  This happened to a few friends and that was cause.  If it were a blue screen/lockup from overheating, you should get a message about windows recovering from a serious error.  You can always check your Event Viewer, filter it for warnings/errors.

I disabled automatic windows updates and I yes I did get a warning message that my computer had shut down unexpectedly. My video card is keeping a steady 77C at 610+ k/h and all my other hwardware components are low on temp so I don't see why my computer should have shut down.

If you have it set up as a dedicated rig you may want to consider linux if the cards are linux compatible.

[zeukin]

Haven't set up a dedicated rig yet. I'm mining on the computer I also work on.

It's getting overheated

[msconfig98]

very likely overheat problem.

[Bansheroom]

Could also be the voltage transformers overheating.

It happens to me when I have the GPU overclocked too much

Nothing is overheating. I monitored my temps while mining and the only hardware that rises in temperature is my video card up to 77C which is not enough to cause a system crash.

Why not partition linux? Thats what I do.

[zeukin]

I will once I build a separate rig just for mining. Now, can someone help me solve this mystery of my computer crashing when nothing is overheating?

I found that not all of the thermoresistors used to measure the temp on a GPU are the same. They can actually vary by over 20%. Try to get the card cooler. 65c is a good temp just to test this. If this doesn't fix it then maybe you're overloading your PSU?

[TiagoTiago]

Could a component that doesn't got a thermometer be overheating?

Btw, are you using an UPS with that?

Not all parts of GPU are monitoring temperatures. Try lowering bit GPU speed

The VRMs of that card may be very hot. Are they actively cooled? Check their temperatures with Gpu-Z

[Itun]

It's most likely the fact that you are overheating your rig.

Another probability is that you have windows update set in the middle of the night.

GPU-z reports same temperatures 77C - 78C under 99% GPU load.

How are the HDDs doing?

How are the HDDs doing?

931GB Seagate ST310005 24AS SCSI Disk Device (SATA) -    37 °C

It could be my PSU or Windows updates since I did an update today.
