Bought this board for pennies that was new but never worked for the guy & has been in storage for donkeys untouched,he mentioned bent cpu pins so i thought it would be an easy fix.
I've fixed the pins and tried to fire it up but its shorting Im guessing the bent pins may have caused the short to begin with or maybe that was just him trying to reattach the cpu cover.. who knows.

Found one of the problem locations on the board just underneath a pcie lane, a voltage regulator that cooked my finger tip.(see pic)

Now i can solder & i have the hot air station but thats as far my skill set goes so i got a new one (B45P03 SOT89) and swapped it out
But the problem remains the new VR still cooks & im guessing somewhere up the line some other components are fried.

I am complete noob with a multi meter and i understand motherboards are hard work but i have nothing to lose with this one.
Cant find schematics so any help with what components to check or decent guides to finding shorts would be greatly appreciated.
fyi i dont have a variable psu would that stop me in my tracks?

Thanks for your time & apologies for any typos or bad grammar still recovering from a stroke.

 

I know of very few people who would attempt the repair of a PC motherboard, I suppose it's because of the lack of schematics/information?

Have you had this mobo in a case? Is it possible there's a standoff were it shouldn't be?

The main failure cause of motherboards is down to electrolytics. Do they look OK? No bulging or leaking.

 

Following up on the previous post, the problem could be a shorted electrolytic capacitor that is associated with the operation of the voltage regulator. So, examine the the board in the vicinity of the regulator and remove the potentially shorted electrolytic capacitors. Test the capacitors or just replace them with new ones.

It might be a good idea to first note the polarity and size of any parts that are removed.

 

Cheers lads.
Yeah i figured that, most of the shops around me wont take it they'll only repair laptops and the one that would quoted £150! :s.
I tried the mobo out of the case the damage was already done before i got it.
The boards mostly solid caps none of which "look" damaged but i'll take the one out next to the hot regulator once my new multimeter gets here & compare it with the rest.

I'll go hit up youtube and see how i go about selecting caps i can replace these with for the time being. & excuse the fluxy mess iv ran out of alcohol ..bar beer .
