Random freeze since... forever

[Trapinator]

Hello, I am having some issues with random freezes when playing games mostly. I bought an asus CM6870 like a year ago and had the problem 2 months after buying it. The screen just freezes with the sound stuttering. The specs were : 286W PSU with 350W peak for 30sec / i7-3770 3.4Ghz / 16G RAM / Geforce GT 640 graphic card/ 2TB HDD and a dvd burner. I recently pimped it up by changing the default case to a thermaltake one, changed the PSU for a Corasir CX600M (600W) a R9 270X 2GB msi graphic card, I watercooled the CPU and bought a huge amount of fans. I think that the remaining original parts are the CPU, the motherboard (ASUS P8H77-M PRO) and the RAM which is 2 ugly 8gb sticks that i can't tell the provider. The thing is that even if I changed the parts, I still got a random freeze last night playing payday 2 .I blame the RAM but I could be wrong. I don't know where or how to get the dmp file with the crash infos but I got in the event viewer and got this:

a 640 calls for a PSU that runs with a 350 continuously and has about 20 Amps on the 12 volt rail, guessing your is underpowered

What are the model #s of the DRAM?

 

[Trapinator]

It's (2 sticks of this) :

Kingston 8gb 2Rx8 PC3L-12800U-11-11-B1
ASU 16D3LU1KBG/8G 9995403-E0G.A00G
6049789- 1251

I also experienced a sudden shutdown today which makes 2 crashes in an instance of 24h. 1 freeze and 1 shutdown. Don't know if it can help

Run memtest for the ram and check your cpu temps.
