Ok so I recently upgraded my PC with fresh sticks of ram(8gb), an msi gtx 980 gaming 4G and a EVGA 600W +80 PSU. I am pulling my hair out trying to understand why what is happening is happening but hopefully someone here could lend some help. Basically what is occurring is total PC crashes while playing games, but seemingly only some games. By PC crashes I mean instantaneous shut downs as if the power went out. I have been playing a lot of Witcher 3 (a very graphically demanding game) and have not encountered a single PC crash, while playing games such as Hurtworld or Counterstrike Global Offensive will lead to a crash within 15-20 minutes of game play. I don't understand the relationship between the crashing and online games and its not stopping, making my experience with my new PC a total headache. Every thread i've seen is hinting at either an overheating mechanism kicking in or a PSU problem but I don't see how either of those are unstable in my case. The witcher naturally will have my PC running the hottest and even then with my fans my cpu will reach a max temp. of 59-60c and my gpu will get to around 79-82c. I bought my PSU around the time I got my card at best buy for 40 bucks, which seems like a decent price for quality. Can anyone help? Thanks in advance.

Edit: My pc was originally a prebuilt bestbuy pc that I stripped excepet for the tb harddrive and the cpu (i5-2320 quad core 3.0ghz).
 
Is your ram compatible and good?
go to the ram maker web site and access their selection app.
Enter your motherboard and check that your ram kit is on the supported list.

Stress test with memtest86+. You should get NO errors in a couple of full passes.

Verify that the problem games have been patched to currency.

Have you by chance turned off your page file? It sounds like the 2 games, which are older titles, are running out of memory and crashing. They may be using the page file for memory instead of your physical ram like your newer games do.
 
I say its is new ram you may have to go into the bios and adjust the settings.. Did you have these issues before the upgrades.... Its always best to do 1 upgrade at a time to avoid issues like this like test the ram first then install the gpu and so on.

So I found out what the problem was and I feel obligated to list it here (having so many unanswered threads as bad experience). Turns out my pc was experiencing minor script and registry errors that were not anything to get worked up about (and were fixed when updating to win10), however, there was a windows setting checked that basically told the pc to completely restart if an error occurred. The good nes is this was no hardware issue.
