Question No POST no BEEP no service

[Came12on]

Hello all... first post
Be me:
Buys new stick of ram same make and model.
Puts in pc.
Pc No longer starts, no signal... fans run.
Finally buys new motherboard after running through the whole troubleshooting process.
Same problem... No signal, fans running

So basically buying a new cpu is my last option... but im scared, what if it still doesn't boot. I think I'll genuinely put my foot through it.

Thanks for reading

The psu is listed in OP but I didn't mention the gpu as I've tried 2 gpus . Suppose I could look for a bend in the pins but I'm not sure how that could have happened while putting a stick of ram in :/

Corsair 550 psu is just the make. they make some good and bad(low end) psu

and what the 2 gpu that you tested?
