Don’t know what to do?

Alright so gonna try to make this short but basically I played during a storm not knowing it was a bad one and ever since then I been getting usb sound disconnects and rgb flickers, mouse doesn’t work, and sometimes audio dies. So I bought a new motherboard assuming I fried the other on and it stopped for awhile but now it’s happening again 😭 should I buy a new power supply now? Cause I’m assuming if it’s not motherboard then it has to be psu. What would yall recommend?

These are my specs CPU- Amd ryzen 7 3700x MB- ASUS rog strix B550-F Gpu- rtx 3070 FE Psu- Corsair RM750i Ram- 4x Corsair vengeance pro 8gb DDR4-3200 Storage- western digital 1 TB m.2
