Heya,
Do you happen to remember what section/option did you change? Usually clearing CMOS applies default options...

I changed dram voltage to 2.2v

Why not try removing the cmos battery then putting it back in after like 5 minutes

I would move RAM to another slot

Try disconnecting the 24 pin psu power cable and the mobo 4pin/8pin atx power connector and then try removing the cmos batt for 10 mins then put it all back together, whilst reseating ur gpu and ram. Then try to boot

At this point, I would start swapping parts. Disconnect everything but CPU/RAM/GPU and start swapping stuff, starting with CPU (which would generally not break but the debug light suggests it is broken or the socket is bad) and has a lifetime warranty. If you have another system to test parts in, I would use that.

sorry but i don't have any replacement part to test but i have checked cpu socket and it fines.

After I went to the warranty center, they said that my CPU had a problem, they changed me to the core i3-9350kf now it works fine. Sorry if I had bad grammar because I'm not a native speaker.
