PC shutting down while playing Overwatch

[simonises10]

Hello,
I have been having a really annoying problem with my pc.
It basically started while playing Overwatch. When it happened for the first time my pc got completely shut down and I even had to wait few minutes in order to get the pc start working again. This also ocurred when I played cs:go. I decided to update all of my drivers and do everything possible to avoid this problem. After that I was able to play Overwatch but after few days similar problem showed up. Instead of the pc shutting itself down the game froze and the only thing that came to my mind was opening task manager and exiting the game. There is always a window saying: Your rendering device has been lost. As you can imagine this was very annyoing because I wasnt able to play the game without getting banned even for entire season. On the other hand I was able to play every other game without having any problem. I once thought to myself the problem could be temperature related so I ran gpu stress program and even when it reached 95 Celsius everything was working normally. As I said deleting all display drivers and getting newest ones managed to run overwatch for couple of days but the result was unfortunately still the same. Another possible cause of it could have been the power supply but why would it only affect Overwatch and not any other games. As far as viruses or malwers are concerned I scanned my whole pc and nothing was found so this possibilty is excluded(I own full version of Eset and Malwerbytes). Worth mentioning that yesterday I tried to play Overwatch once again, however my pc got completely shut down. Im pretty desperate and I dont know what to do at this point therefore I tried almost everything. Hopefully you guys could came up with some idea...

My pc specs:
Windows 7 Professional 64-bit
Intel Core i7 5820K
24 gb ram
X99A GAMING 7 (MSI motherboard)
ATI AMD Radeon (TM) R9 390 Series (390x)
(If there is anything more you would need to know I can add it)

I used to use msi afterburner and with it I underclocked my pc to get rid of loud noises which were made by fans. At this point I only use wattman software provided by radeon settings.
I asked several people in the chat while playing Overwatch and they said they had similar issues but it is still weird.
Ive only had this pc for a year so it shouldnt have problems such as these..
Sometimes the pc shuts itself down and immidiatelly restarts and sometimes I have to switch it on manually.

PS: Keep in mind Im only 16 and dont know that much about computers and also sorry for my english (Im from Slovakia) and sorry that this text isnt ideally structured (I wrote what came to my mind at certain moment). :/

95c is too hot for the gpu. You need to fix that but it may not be the cause but you cannot rule it out just because 1 stress test did not crash.

Also what make and model PSU do you have?

make sure that ur gpu fans are even running man 95c is tooooooo hot its like u dont even have a thermal solution.

I think this might be the one: http://www.fsplifestyle.com/PROP161000013/ (not sure about the watts but it looks the same). Anyway as I said no matter what I play it works except Overwatch. I underclocked it – temp. was around 66 celsius – crashed. Did not underclock it – 72 Celsius – crashed. Same outcome...

Fans are running normally. And AMDs, especially this one, are really hot. And the maximum it can be is 105 Celsius I reckon. So I think temperature is kinda normal.

95'c is actually pretty normal for a reference 290/390x.

I suspect the PSU is the problem.

So the PSU can still be the problem even If it only happens while playing Overwatch?

That 105c is when it will shut down to protect itself, you will suffer thermal throttling before that and possible stability issue. Ideally that gpu shouldn't go over the low 80's.

I don't know that brand of PSU, the specs look good but have no idea about the quality which is more important.

If its just Overwatch I would start by reinstalling the game but out of interest what other gpu demanding games do you play?

I also play Battlefield 1 on ultra, no problems, temperature is under 80, The Witcher 3 on ultra, no problems,
Fortnite on high, again no problems and other games.

Then I would start with a fresh install of Overwatch. The game is a genuine copy, its not some cracked version?
