PC STOPPED WORKiNG

[lorenzodemonti18]

Hi, I have a tower working perfectly, when suddenly it shuts down, and the hard drive started making a strange noise for about 10 second. PC won't boot anymore. So I decided to disconnect the hard drive and the PC won't boot anyway.
In the tower I got a generic motherboard from a pre-build Asus PC, core i5 3330, GeForce 620(Just for the video output) 🙁 , hyper 212 Evo air-cooler , and a generic power supply 350w.
I thought that the power supply was dead but I tried with a jumper and it still work.
There's a green led on the motherboard that turn on.
I don't know what to do.
PLEASE HELP

A PSU my power on, but it does not mean that it can deliver the power the PC needs.
I would try another PSU and see if the system boots before trying anything else.

You may have suffered a hard drive failure, especially if you say the drive itself made a strange noise.

Maybe... I'm gonna try with a 700w power supply and I'll let u know

Probably it's a hard drive failure, but the system should boot anyway if I disconnect it, right?

The system should be able to power on and you could get into the BIOS even without a hard drive.
Are you able to do that?
The system will not boot into the OS, if the disk where the OS reside has failed.

No, the system doesn't turn on even without the hard drive and I'm not able to get to the bios

That does not look like a disk failure. Even if your disk dies you should be able to power on and access the BIOS.

You may have had a capacitor or something else pop/short on your mobo. What I'd recommend at this point would be to remove it from your case and carefully inspect it to see if any such damage is apparent. If you're not comfortable removing it entirely, remove as much as you can to make the board visible for inspection.

You don't need a 700watt psu,just get a good quality one.Something of 400watt would already be more than enough for what you have and even 300watt would do,but if you maybe wanted to upgrade with a suitable gpu would a nice 450watt mostly be fine if not going very high end with that gpu.

Pretty sure the 700w PSU mentioned was just for testing purposes.
