Dead PSU - Dead PC

[bsemp86]

Hello everyone,

Yesterday my PSU decided to fry itself with an spectacular bang. I tried to find anything burned on the mobo or graphics card and everything seems ok.

The problem is that today, after installing a brand new PSU nothing works. Mobo and graphics card receive current (let's on) but trying to start results on a light movement of the fans and silence, nothing boots.

Any ideas?

Thank you very much!

Well something went out with the PSU...If you have a spare PC, try to check out what exatcly doesnt work.

Error codes? Speaker? No speaker?

I had more or less the same problem,

that's why I bought a PSU with over current protection ;D

 

I would test everything one by one in a different pc, as you gave very little details, so we can't help much .

Was it a cheap PSU?, some bad PSUs can take other components with them when they die.

try clearing CMOS, if that doesn't work, prepare the longboat...

 

D: oh noz.

 

 

OP, your whole computer could be at risk when it comes to PSU failiure. I suspect foul play with your motherboard, and even your graphics could have been hit, because who knows, your PSU could have sent a giant surge of electricity before going off with a bang.

Never cheap out on the PSU.

If it goes out it can take out everything connected to it, even USB connected devices.

 

You'll now need to find out what's dead, it's clearly taken something else with it.

Thank you very much guys. It wasn't a cheap psu wen it was new was really expensive. It was simply old.

Nothing posts or beeps or shows on screen and I can't test anything on a spare computer. This particular one is a lga1366 socket and the other I have access to is something from amd.

This afternoon I'll try to troubleshoot slowly everything. If all fails I'll come back to you guys with questions about a new computer

Well, after many attempt and combinations and CMOS reset I came up with a plausible cause.

It all fails when I connect the 8 pin dedicated to cpu power and it refuses to power up. Also with a multimeter it appears that the pins are shorted out (12v to ground).

I am begging to feel bad about this, do you thing it's dead or it has some fancy solution?

Thank you very much!!
