Hello guys. After searching about 3 months around to find out why my computer is restarting randomly while playing games i am here for your opinion and ideas. My pc build is i7 5820k, Kingston KHX2133C13D4 4x4 DDR4 Quad Channel, Ashrock extere 4 X99 motherboard and psu Coolermaster G750M. I used to have a GTX 970 Nvidia card but recently i updated to GTX 1080 ti Gaming X 11G from MSI. I also bought Asus Rog 2k Gsync monitor for the graphic card. Since then sometimes when i use max settings (so i push the card) with gsync on or not my computer restarts. From what i have seen i am fine with temperatures but my computer restarts when the demand of gpu goes close to 100%. I tested from task manager. I have done clean format of windows because i thought it might be from there. I send you files from my dxdiag and msinfo32. I am thinking it might be psu problem i just wanna be sure cause i dont wanna spend money without reason. On the end of msinfo32 you will be able to see also the errors i got when computer was restarting. All drivers are updated and bios also.
