Needing help with my dell vostro 230. its all original.

[neff11]

about a week ago my 3 year old plugged my usb phone charger that i had plugged into my pc into the wall socket.Well with a big shock and a smell of burning parts it wouldnt turn back on. Since then i havent been able to get it to boot, the power supply standby light on the back and front light up. Ive attempted just plugging the pcu and mother board in with no change changed pcu's with a know good one, still nothing, what could other possible issues be? no fans or post beeps come up, even with only the board plugged in. im a rookie builder i mainly just update my own system as needed. i'm thinking its the mother board but i'd like to get a little feedback from someone that actually knows about computers. thanks. its vostro, gt 610 graphics card, removed for time being, it had the original pcu in it cant remember exactly what it is off the top of my head, i tried my extreme 2 quad qx 8650 and still nothing, was waiting my my new graphics card to hook it all up which was on order for about a week before she blew it up. 2 ddr3 1333 cards, a 1 and 2 gig. other then that its just a standard jl1117 board.

If you're not getting any POST errors and fans plugged into the motherboard aren't spinning up (also check the CPU fan to see if that spins) then it is most likely a dead motherboard. Which would make sense as the USB headers all plug directly into the board so unfortunately your motherboard will have taken the brunt of the shock. Not sure of the quality of the DELL board but I would check your other components that were attached to the board at the time if possible, some motherboards will be able to protect the other components at a time like this but not all.

HI, I'm not sure I followed everything in your post. Any part could have failed when 120V A/C hit the MB via the USB ports then travelled power wires just about everywhere.

I'd start by removing all parts and wires from the MB except the CPU, CPU fan, two power connectors from the PSU and teh onb/off switch. Then try powering up and hope to get the "no memory" beep.

If nothing happens I'd swap the PSU. I think from your post you may have done this already with the MB stripped down. Is this what you meant by "... Ive attempted just plugging the pcu and mother board in ..." ?

IF the bare MB, CPU and know good PSU don't work I'd replace the MB, $50 on ebay, and hope the CPU didn't fry also. Note when you replace the MB you have the option to move to a more modern MB + CPU + Memory solution. The dual core E7500 was a nice CPU in its day, but a $70 pentium G3258 in a cheap $50 MB will run rings around it. http://www.tomshardware.com/reviews/pentium-g3258-b81-cheap-overclocking,3888.html

Yeah I've stripped it down and did the basics like it said in a different thread I found on here. Even with only the mb pcu and pcu fan plugged up there was no life my new board should be arriving today or tomorrow, I'm going to stick with my lga 775 sockets just because I have a few cpus sitting around for it. But I have a new graphics card and 2 good pcus to test the new board, ( ive got an Intel qx6850 to go with the new board, and a brand new gt 710 to replace the 610 I had. Been thinking about getting a bigger ddr stick any ways so if they're gone I'll just get 2 new 4 gigs) if need be I'll I'd have to do more is buys a few ddr sticks, thanks for the tips though. Just wasnt 100% sure on where to go next

Nice. Makes sense. Good luck. I still have two q6600 systems running, and a qx6850 is much faster than a q6600.

IF you upgrade to qx6850 use the HSF that came with the 6850 if you can fit it in case vs. the original HSF. The qx6850 is a 130 W part, and the original HSF probably wasn't designed to handle that much heat, especially in a small case.

Thanks to every one for your help, I'm typing to you live from my now working pc. Pcu:qx6850 mb:asrock g41m graphics: nvid gt 710 original case fan, dual fan 600 watt ps, and 92 millimeter pcu fan. About to reattempt to put these kingston 4 gig hyper-x ddr3 1333mhz in and see if I can't get this baby up to full power.
