Been asked to fix a pc again, it needed a new powersupply so I fitted that. All good, mother in lA picked it up, took it back when they got home something had happened as a stick of ram was out of its slot (lord knows how) now it’s no displaying anything.

I’ve taken the whole pc apart taken out the cmos battery. Replaced everything. And the bios flickered on for a min then selected boot and it returned to no display.

Can’t think of anything apart the mobo is fried, any advice?

All it will do is start, run for 30 seconds, and not post then boot loop and restart. I have to shut it off from the power supply to turn it off as the case button won’t. This happened with my original build, so I replaced the motherboard and cpu, thinking it was my old cpu since I had a bent pin on the last one. Yet, the problem persists. I bought a new motherboard that has argb unlike the old one, and my argb fans will flash when I turn the psu on and then never fully turn on. I’m suspecting RAM or PSU considering it won’t post. The PSU was used and bought from a friend working.

CPU: Ryzen 5 4500

Motherboard: Gigabyte B550 Eagle WIFI6

RAM: OLOY DDR4 RAM 16GB (2x8GB) 3000 MHz CL16 1.35V 288-Pin Desktop Gaming UDIMM (MD4U083016BJDA)

GPU: ASUS GTX 550 Ti(yes yes, I know it’s old, but it should be working as the pc problem persists even when I remove it)

PSU: Thermaltake Smart 650W 80+ Gold Non-modular power supply(it’s an older one)

Case(if needed): Corsair 3500X ARGB

it stops immediately after exiting the game

note:all of the pc parts are new except for one hdd.

could it be a virus? I’m suspecting a cracked game to be the reason , couse when i changed the MB the sound disappeared until I lunched the potential reason.

Today I turned it on and it worked fine for ten minutes until I opened YouTube on a browser and right about when it was ready to load the computer suddenly turned off.The pc wasn't turning on again.I changed the power supply and the pc turned on but the pc turned on when I pressed the power supply's button(Which is strange because It should turn on when I Press the power button on the case).The pc did turn on but there was no output to the display,the fans were all running, the hdd and CD drives were not running and when I turned the pc on the motherboard speaker (Which usually makes a bip sound when i turn the pc on)the was no bip sound.Also as you can see in the video in the front io were the led lights are the red is always on while the green is blinking very fast.In conclusion I found out that the power supply is broken.If anyone knows what else could have been broken please respond.

Edit: found out that the psu died and took the motherboard with it.
