SFF 6300
Microsoft Windows 10 (64-bit)

Dear HP,

 

I am using HP SFF 6300 for a while but today morning when I power It on. It turns on and then turns off automatically.

Back in 2020 February I am having the same problem but in that condition I remove everything from the PC (every wire) after sometime the PC start but only power light is visible with not beeps what's so every and fan started running at full speed after that I again restarts the PC  It did starts perfectly. I think it a processor problem so I replaced it with New i5-3470. Here in India Idle temperature stays like 25-40 degrees and I always set my CPU Fans at high speed because I don't get bother with CPU noise and the idle Temperature stays about 30-40 on A/C room. But today it not even starting just turns on and turns off immediately fan spins and stops. I have check the power supply power delivery it seems fine I tried on other SFF it works quite well on other. I also tried other SFF power supply on the dead system but it remains same.

I am not an expert in finding or tracing out where the error. 

I tried removing both ram stick in hope the system even starts beep or red-light but nothing happens.

I tried removing CMOS Battery for more than 10 minutes still same.

I removed all peripherals even internal component such as HDD, CD/DVD DRIVE ONLY CPU AND MOTHERBOARD CONNECTED.

 

Is it a Motherboard Issue bcoz the older CPU is working fine on other system.

I don't have any BSOD or Freezes during operating the system before.
