Question Motherboard

[Captensomething]

Can I soak a mother board in isopropyl alcohol

 

[USAFRet]

Maybe.
Why?

 

[AllanGH]

Well, the easy answer is "absolutely", but, yeah....as USAF Ret asked.....why do you want to?

 

[Captensomething]

I got the pc from a machine shop and the entire mother board was covered in gunk but still functioning except the pci slot but I tried dipping it and scrubbing with a soft tooth brush but I put everything back together and now the pic isn’t turning on and I think it’s because I left the bios battery in it

And this is why the whole backstory is important, and leads to...Why.

So you scrubbed it with....what?

Isn't turning on....what does it do, specifically?

Submerging your motherboard in Isopropyl Alcohol will damage the thermal pads under the heatsinks.
Also if it is not 99-100% pure it can leave contaminants behind which could damage the CPU socket and RAM slots.
IMO you would be better off dipping a soft toothbrush in the Isopropyl and lightly scrubbing the areas you want to clean.

With a tooth brush and isopropyl alcohol and now the whole system isn’t getting power the lights don’t turn on the fans don’t spin nothing happened when I press the button

never submerged it just poured a little on the area I was cleaning and let it dry after scrubbing

I would guess that you pouring the alcohol onto the board is the cause of your issue.
The Alcohol probably got into somewhere it shouldn't have.
You should have dipped the brush into the alcohol.
How long did you let it dry before you tried to use it?
You could try using a hair dryer to heat it up a bit and possibly remove any alcohol residue.

I waited about five hours before putting everything back together do you think it was because I left the battery in it when I was cleaning?

That is possible, you may have shorted the BIOS chip.

 

[Captensomething]

Is there anything I can do at this point

 

[DMAN999]

I would remove the battery and use a hair dryer on the entire board.
Then put in a new battery and see if it will POST.
You never know, you get lucky and all it will cost you is a bit of time and $2-3 for a battery.

I tried three different battery’s including the one in my pc I think it’s just done

Consumer-grade isopropyl alcohol can typically have up to 40% water in it. If that's the grade of IPA that you used, you didn't wait long enough to allow it to dry. A couple of days certainly would have been a good idea.

Or using anhydrous isopropyl alcohol, instead.....

50% and I left out on my porch for a little bit to let it get a little dryer

 

[AllanGH]

Yeah....give it a few days and try it again....see what happens. It may not be a dumpster Frisbee yet.

I hope so cause I don’t have the funds to replace that’s why I was excited about a full build for free it is a
Gtx970
8g ddr4 ram
EVGA power supply 500w
a i3 processor
Asus mother board

 

[Captensomething]

Another thing that’s getting me is the power supply isn’t even turning on

The best way to address the power supply would be:
