Hello there.This is my first post here.I am from India and i need advice regarding some hardware problem.
First my PC Specs
AMD FX 4300 CPU
Seasonic S12II Bronze 520W PSU
Motherboard: MSI 760GM-P23 (FX)
Ram: 4 GB Corsair 2 GB EVM
HDD: WD Cavier Green
GPU: Sapphire R9 280x
When i got this rig for a year i didnt change my fan speed in bios.They were very noisy running at 100%.At over 6000RPM my CPU Temp was at rediculous 120 low.After a year i came to my senses and changed it.So i set it down at 15% minimum speed.The cpu fan is somewhat wheatherd.
Now coming to the actual problem.In india we have electricity blackout problem.I lived in an area were no blackouts happened and then shifted to an area where it happened frequently and now i live in an area where frequency is medium.But definitely once in a day it happens, though for a very short period.15 min-20 min.I dont use UPS.I brought an ineffective one which is a very seperate story but i dont use it.
[(When lights go out my pc shut down) obviously]
So, after elecricity comes back up after blackout and when i start my PC my PC goes through three phases.
A.It starts up then after 0-5 minutes it shutsdown.
B.Then when i hit power button usually it starts and shuts down within 0-5 seconds.This can happen twice.
C.Then i hit power button.It starts, you can play games for hours, do about anything and it wont shut down.A proper restart is also very responsive.This i let happen 20 times or more because i am in middle of an exam and i cant send parts for RMA.Also RMA would take probably a full month or at least 15 days where i am from.
Observation made:
CPU fan doesn't spin many times during phase one.
I update minimum fan speed to 20% which is a bit noisy but all temps are fine as measured by HWMonitor..

All advices are welcome.Thank you for reading.
