About a month ago my desktop just stopped. Would come on but shut down after few min. Took to repair guy and had fans replaced and had new motherboard and ssd put in. He thought I had power surge that fried motherboard. Went to use computer yesterday and it wouldn't come on at all. Just dead. I had it hooked up to new battery backup surge protector.
Any clue what could be happening??

Why the frick wouldn't he have replaced the shitty power supply too?

If repair guy thought it was a power surge and didnt - at minimum - suggest you replace the PSU, then he was flat out negligent. If he suggested it to you and you declined, then thats on you.

Why assume a power surge existed? How many other household appliances were also destroyed by a surge?
How did a surge get into a motheerboard without passing through the PSU?
What part on a motherboard was damaged? If he did not know that, then he did not even know if a motherboard is damaged.
A power supply will not power on until a power controller authorizes it. Only a power controller decides when a PSU will power off. Why did he not discuss that power controller?
If a surge existed, then hardware is damaged - would not even power on or boot. So many who repair computers have no idea what a PSU does, how surges do damage, or even what a power controller is.
A constant defect in a power system sometimes works fine and sometimes causes failures. Which power system component is defective? Only tools such as a digital meter can say.
Informed techs never disconnect one wire or replace a part until after a defect is identified. Meter is essential.
Did you have a battery backup (UPS) or a surge protector? Completely different devices. A UPS might have a few hundreds joules. Near zero. Too tiny to avert any surge. But just enough above zero to hype a UPS as 100% surge protection - subjectively where it is legal to lie subjectively - in sales brochures.
If a UPS, then best protection must be in a PSU.
I can list something less than 50 different reasons for your symptoms - that are only subjective. Start again. Informed assistance requires numbers by getting a meter, requesting instructions, and performing two minutes of labor. What follows is an answer without any more "it could be" expressions.
Long before any other part can be suspected, first a power supply system must be known good. Not speculated good; known good. Otherwise other perfectly good parts (ie motherboard) will act defective. Informed answers always first require numbers.

Not the whole story, and I expect you've been told that many times before.
