Question PC is ON but won't boot ?

[argomukiono]

Hi, folks, I have an issue with my PC.
Suddenly a few days back, my PC won't boot but it is ON (lights, fan, etc, are on). Then I decided to clean all the stuff inside, did guessing that it caused by dust. After it done, I did assembly all the parts and turn it on, and it did boot, so I decided to changed the setting of the priority boot hard drive in the BIOS. Then, it worked normally.

And the next day, I turned on my PC but it happened again, it won't booting but the PC is on. I guess it has the problem with the hard drive, but it did not I think. I did unplug and plugged in my hard drive, but it happened all the time.
My PC wont entering boot after it turned off.

I did some troubleshooting, but signed no good solution :

• Check the CPU if it any bent pins, and it's not. CPU is normal.
• Reinstall the RAM and GPU
• Clear CMOS
• Updating the BIOS
• Using only my SSD to boot

Any suggestions?
Thank you.

When you say "Not booting", does that mean no picture of BIOS or no Windows ?

No BIOS. Monitor keep turned off.

No BIOS. Monitor keep turned off.

Possibly PSU, if you can try another GPU.

Today my PC is suddenly turned on normally, but the bad news is, after turned off, then it won't post again. It's so confused me.
I'll try your suggestion, Mike. Thanks for the advice.
