Question PC keeps shutting off when powering on ?

[iits1uca]

So once I click the power button my PC needs 3 attempts to start and the BIOS always gets reset.
Once it's fully powered on I have no problems until the next day when I power it up again.
Any ideas?
Have a i5 9600k on a asus rog board with 32gb xpg ram, and a gigabyte 3060 with a Thermaltake 700w powersupply
Should be 4-5 years old.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (orginal to build, new, refurbished, used)?

For the most part, I would suspect the PSU.

Requires a few attempts and warms up in the process. Expansion somewhere and full contact is made.

Likely something loose. Where that is being the question....

= = = =

Power down, unplug, open the case.

Clean out dust & debris.

Verify by sight & feel that all cards, connectors, RAM, jumpers, and case connections are fully and firmly in place.

Inspect for signs of damage. Swap in a new CMOS battery just as a matter of elimination.
