OK I'm dumb. Here is the new log, crashed about 10 mins into playing TF2.

So sorry about the late response, I had some other problems.

Anyway here is the file. It was taken about 5 minutes after the last crash.

I rolled back the GPU driver to the last one, but it crashed anyway. I'll try to revert some others these next days, just in case.

Also, this is the log of the GPU-Z after 10 mins of playing:

• GPU Core Clock - 324.0MHz
  
• GPU Memory Clock - 162.0MHz
  
• GPU Temperature - 39.0ºC
  
• Fan Speed - 30%
  
• Fan Speed - 810RPM
  
• Memory Used - 133MB
  
• GPU Load - 2%
  
• Memory Controller Load - 3%
  
• Video Engine Load - 0%
  
• Bus Interface Load - 1%
  
• Power Consumption - 11.2% TDP
  
• PerfCap Reason - 16
  
• VDDC - 0.8750V

I try to update them at least every month.

Oddly enough, yesterday I ran the Heaven one for almost an hour in the daytime and nothing happened (although the temperature went up to 77ºC at some points), but then the computer shut down in the evening while playing for 30 mins. The PSU temperature was even lower than the last time (33). Am I doing something wrong here? :/

You can find a couple of old forums about the black props here and here. Maybe there is a fix for your problem there.

Alright, ran them both for about 30 mins and the temperature was slowly going up until getting capped at 76ºC. Did not get any crash tho. Should I maybe run the benchmarks for longer periods of time?

I looked for critical errors on the event viewer but didn't found anything relevant from when the crashes happened. I already have the max performance enabled too.

Ok, I'll monitor the temperatures from the next couples crashes to see if they are the same. Can you tell me how to run those stress tests tho? Thanks in advance.

So I finally got these results:

• When it crashed (was working for about 2 hours): 37C
  
• When it loaded again (about 10 - 15 mins later): 32C

OK I'll try to do it, I was just saying that maybe those old thermometers weren't good enough to measure the exact temperature of the PSU.

Just finished running it, didn't have any relevant issues (I guess?, I'm a noob with BIOS stuff)

Unfortunately I don't think I'll be able to measure it precisely, the only thermometer we have at home is a mercury one with a 40ºC limit :/

Ye, the PSU is still the most likely problem but I wanna be sure before spending money on a new one.

As I wrote down all the specs above off the top of my head, I made a mistake about the CPU. It's actually an Intel Core i7 3770 3.4GHz. Sorry about that.

Nope, it doesn't freeze or do anything special; it just shuts down by itself (to clarify: when this happens the PC doesn't show the "turn off" screen as when you select it from the start menu, the case just powers off and the monitor goes to black).

I ran speedfan to check the temperatures, and they seem normal. I recently (like a couple of weeks more or less) cleaned the dust from inside the computer too.

Can't remember all the details of the processor right now but I know i've never overclocked it.

Hiya.

So, I've been having issues with my PC since a month or so, it just shuts down by itself and it (usually) keeps shutting down repeatedly if I try to reboot it afterwards. It's pretty much random, some days I get no shut downs even after 4 hours of continuous usage and then the next day it happens after just 15 mins.

I was thinking that the issue could probably be the PSU, but I don't want to change it blindly and then finding out that the problem was something else. Any ideas of what should I do?
