PC configuration:
gigabyte z170 xp sli motherboard
gigabyte windforce gtx 960 oc edition GPU
gigabyte pulse 650 watt powersupply
corsair 8GB ram
core i7 6700k CPU
(i did not overclock CPU or GPU for a long day, and windows update is turned off)

From 2016 may to 2018 1st June, computer working fine and everything OK, Next day I started playing games GTA V, suddenly blue screen of death come and restart normally without problem, in event viewer i saw critical problem on kernel power.

I noticed while chassis is open and playing game, very little buzzing noise come from system when i get close to the system, but i can not figure out from which component. probably gpu or powersupply.

I started playing game again and again, every time blue screen of death come, every time computer turning off and on repeatedly in second that boot screen(gigabyte ultra durable logo) or windows logo does not get much time to appear. I changed ram to another slot to fix booting issue every time. But after few boot i realize that windows get corrupted,



Windows stated but, after windows 10 logo no signal in monitor. I removed HDMI cable from GPU to onboard graphics by changing setting in bios, but not worked, then plugged the HDMI cable back to GPU. I have find solution by chatting with Microsoft support assistant, They told me to disable display adapter from safe mode, because that time safe mode working with monitor. and this works for me but it stuck at logon screen with some icon at bottom right corner. After that i have contacted again to assistant by chat , by hearing everything they told me to reset my windows by deleting app. but i do not want to delete programs. Then i decided to repair windows with a third party app,

(note that- one time blue screen of death come in safe mode while i am doing nothing, and one time while i am trying to uninstalling nvidia graphics driver)

Third party app name is "windows repair all in one by tweaking.com", i boot into safe mode and run this program with common troubleshooting preset, I run repairing with this program and after repair completed, i restarted my computer with welcome logo and no signal in monitor but again disabling graphics driver from safe mode. Now I can normally startup my PC but with graphics driver disabled.

But I am sure that hardware problem not fixed yet. I did not understand which of these component causing problems.
