Pc turning on ups battery power only. And random crashes

[DazzlerTony]

Hi,

I'm facing a strange issue with my pc. I bought this last year in June. It was running fine till now. But from last month I've observed that pc won't start on pressing power button. So I found a solution for this that turning off power supply switches ups to battery power and pc starts. When the boot completes I can turn on ac power.

 

But from last 2-3 days it is getting crashed randomly. And from today morning I'm not able to boot it completely. Whenever I'm trying to start using battery power it starts and turns off within a minute or two. And once it is crashed I've to again turn on ac power and then turn of ac power and press power button.

 

Sometimes it shows ezdebug Cpu led and sometimes ezdebug dram led. And sometimes it boots and I can enter bios but if I make any changes in bios and try to save and restart it again crashes.

 

I've tried clearing cmos by removing battery cell for 5 minutes.

Also tried jbat.

Also tried POST Test, by removing all parts and adding one by one but no luck.

 

In bios cpu temperature is around 42•c, motherboard temperature is around 38•c

 

Is there any issue with cpu?

I removed it from cpu socket and saw thermal paste is having more fluidity than normal. I accidentally bent some cpu socket pins but I've fixed them. So that is not an issue.

 

I've tried different wall sockets with and without ups. But got no success.

 

 

my pc specifications are as follows.

 

Intel i5 9600k

MSI Z390 Gaming Edge AC WiFi

2x GSkill trident 8 gb 3000 mhz cl16

2x GSkill Aegis 16 gb 3000 mhz cl16

Thank You!
