Help: Wife borked computer with M.2 SSD

[KappW]

Hi! So, *someone* in the household tried connecting a M.2 SSD by sticking it into a SATA power connector. It never powered up after this -- not even briefly -- and was completely dead, even when aforementioned SSD was removed.

I've tried disconnecting and reconnecting everything, but it still doesn't power up. No lights, no beep(s), no nothing.

The PSU seems fine, and starts when I try the short trick between the green wire and ground with a paperclip. The fans, HDD and LEDs do power up when I do this, but the computer does not boot. A LED marked DRAM does also light up during this.

LEDs also flash very briefly up if I pull the ATX power connector halfway out and wiggle it a bit.

Absolutely nothing happenes when all the power connectors are properly in place.

I've tried resetting CMOS by removing battery, removing one or both RAM sticks, removing GPU, removing HDD etc., but still no dice.

Anyone got any idea about what the problem could be, or other tricks that might work?

 

Update: Tried with a new PSU, problem persists.

pull the ram out and see if it'll power on then.

i think your psu might be shorted.

if you're lucky the psu fuse might broken, just replace the fuse.

[Dedayog]

Not sure how that could fry a motherboard, if it shorted then it would stop back at the PSU.

 

Other than that I am vacillating between laughing my ass off and horrified someone would actually think to do that!

 

Least you have a sweet story for years, that's worth more than an SSD anytime

Point number the first: this post made me laugh more than anything else I've ever seen on this forum.

 

If you have another power supply lying around,I'd try that. If not, I'd try and pick up something insanely cheap on craigslist for just a single boot. Doesn't need to be high wattage, just needs to work. If that didn't work, I'd say it's a bad motherboard.

I would guess she damaged the internals of the sata connector and it is constantly shorted. She could have also shorted the PSU.

Curious why he didn't list the PSU but listed the rest. The PSU is kinda integral here.

 

If it's modular, replace that cable then.

Try cutting off the sata connector header.

Tried opening it, but the only fuse I can find is soldered on. Not able to see if its blown or not. Would the PSU still run if its blown? As mentioned, it starts up when I try shorting with a paper clip.

Haha! Yeah, of all the technical f-ups we've had here over the years, this one is definately one of the better ones

this is the best start, since it fried the 12V rail likely shorting the 5/3V down graders, the system wont work properly

 

having recently experienced something weird a jumped PSU spinning up doesnt mean its good.

1- old 700w OCZ idkmodel whocares. i only use it for stuff, and jumped to prime the system with out dealing with the mobo connector (i just unplug at the wall to disconnect everything)

2- building new system as a gift with old part i dont use any more, waiting on the amazon order to finish the system (new psu most importantly for this)

3-couldn't post the used mobo, thought i was served a lemon.

4-2nd' old psu for similar purpose's but only 500W POS idk,  and same thing.

5- tried the psu from my down at the time system and the 850w worked.

6- both psu that wouldnt post, spun up/jumped fine, but wouldnt post the mobo

estimated wattage use of the system at load was like 99W, or something redic low

since gift reciever doesnt need a GPU,  i subbed in a decent old cheap APU

[KappW]

UPDATE: Got a new PSU today, but the problem persists. Still no life whatsoever. I guess this means that the mobo is likely the problem? On the plus side, I've got a spare PSU now for a later rainy day
