Well my psu 380 blew up and im affraid it damaged something cause i went to the store and bought a 650. I dont know if it damaged my cpu or my motherboard i know for a fact it didnt damage my ram or video card. Are there any signs of cpu or motherboard being broken. I put it all together and it starts running but nothing comes up on the screen. plz help me

never having had a PSU blow on me, I'm going on other people's anecdotes, but yes It is quite possible that your PSU's death took the rest with it, I think one would normally check for broken or bulging capacitors.... but as I Say, no 1st hand experience

I did check nothing looks damaged.

When you get a new power supply if it did you will find out, i hope it did'nt

I wouldn't say the PSU on my uncle's computer blew up, however it did die. I replaced it with my old 580w Hiper and she was running again.

Good glad to hear it alway nice to here a good ending

We kissed and make up and she purred away as the old work horse she is .

I assume that means you've tested these parts in other systems? I hate to say it, but odds are there was some kind of damage to your motherboard. Could be the CPU, but without another system to drop the chip into and check, theres no way to really tell.

I think the OP did replace it, and its not working, hence his post.

Exploding weak PSU would most likely damage the motherboard, though if it dies "exploding enough", anything could get damaged. I'd start with the motherboard first.

When a PSU dies, it sometimes is a matter of pure luck whether or not it takes something with it. Depends a little on why it died, I think. If it was just a resistor or something giving up, it might die peacefully. If a short got involved, that could fry the motherboard and/or CPU. Since the ram and cards are on the other side of the south bridge, they often survive better than the motherboard and CPU.

To test the individual parts, they can be tried in another computer if one is available. Often times the way a motherboard is found guilty is when the CPU, ram, and PCI/PCIe cards work in a different computer, but not with the suspect motherboard.

Sailer, I thought you were better then that. Cards do plug into the SB, but ram either plugs into the CPU or NB. (AMD or current Intel CPUs.) You are right however, cards and memory does usually survive.
