2 random PC crashes

[Spev]

So I usually have no problems. Today I have gotten 2 random PC crashes. They have both been while I have been downloading Far Cry 4. I am doing stuff in the background. They stop responding, then all close, then my PC just shuts down. No blue screen, just auto restarts. After the first time I monitored my hardware. CPU usage was literally at 1%, was using about 3.5 of my 12 ram, and temps were fine. 

 

However this has only happened while downloading my game, could this be an issue with my harddrive?

Were you downloading any updates for other things or something?

Are there any memory dumps in your temp folder?

Were you downloading any updates for other things or something?

No, I was just watching some YouTube vids, checking out some product reviews, probably had about 5-7 internet tabs up, as well as the uplay client for downloading Far Cry 4.

 

My HD is like 4 years old. The reason I was mentioning it is because maybe with all the files being written to it from the game is overheated or it was too much for it. My current PC only has one 2TB HD, it's really nothing special, I'm just wondering if it could be the problem.

Are there any memory dumps in your temp folder?

I'm looking in it, but I'm really not too familiar with the temp folder. There are some folders within it mostly for NVIDIA stuff, and a bunch tmp files and other stuff...I'm not sure how to identify a memory dump.

 

Edit: I'm going to just download Far Cry 4 here (which is gonna take forever, during the 2 times my PC crashed I had to restart the download...) and not really do anything in the background. I think it will work just fine like that, but I still want to figure out the culprit for this to avoid future issues.

Just got another crash while downloading Far Cry 4....anyone actually have an idea why this is happening? This time the only other program I was running was Microsoft word...

You can monitore your HD with HWinfo64, including temperatures, read/write-speed and SMART-Status (self monitoring of HD), in case you're interested.

Try to put another load on your Line (i.E. Download something big), and make shure Uplay is not running. If it crashes again, I would point towards LAN/NIC/Drivers (Edit: If your HD's fine) - if it doesn't, I would point at Ubisoft (seems to be common these days).
