ready I checked the capacitors and apparently there were no defects, I cleaned dust and now the PC turns on but gives 5 short beeps and stays there
the source connector is somewhat loose
The most common in beeps is that it indicates memory or video failure.
That the source connections are loose is bad, that is making false contact and with less contact surface can overheat by the amount of current that passes. Try to correct that.
Try a single memory.
Well since I tried with a single memory and it didn't work out because the red lights follow, for now I have fixed the source to avoid false contact
I'm going to check the tensions and the mosfet
