Question My PC needs two boots to boot properly

[hergarcia]

Since a while, my pc has some problem to boot. After a long time powered off (like in the morning) my pc needs a second chance to power up. When I press the power botton, it get stucked in MSI logo (where you can look "press del to enter BIOS", etc). I need to long press power botton to force power off and then power on again, then it boot correctly.

I upgraded and downgraded bios version and the problem persist.

I wonder if it could be a ssd issue?

Make and model PSU, wattage, age, condition?

Has the case ever been opened for cleaning and reseating of all components, cards, cables, jumpers...?

Could be loose connection that fails to maintain connectivity when the system is cold. After the first boot/startup attempt, things warm up and the connection tightens.

Build it's totally clean, I recently disassembly it and change all the wires to verify all work properly but the problem persist.

Clear CMOS and resave BIOS settings, after that, maybe a weak PSU problem.

CMOS and BIOS reset didn't work. What you mean a weak PSU?, I have R5 2600 and gtx 1050ti i don't think it is a problem
