Just took out RAM with PSU turned on and now PC won't turn on

Go to solution Solved by Mark77,

An ATX PC isn't really fully powered down unless you remove the AC power from it, or turn a switch provided on the PSU for the purpose.  If you just soft-powered down (ie: with the front-panel switch, or by shorting the proper headers on the motherboard), you may very well have corrupted the currently executing code, but not damaged anything.

 

So do a full and proper powerdown, and then try again.  On some machines, if you pull components with things powered up, sometimes the configuration settings get wiped out and you'll have to go into the BIOS/settings and re-do everything.

My pc was beeping, so I went to check the RAM sticks, and I accidentally took them out with the power supply turned on...

Is my motherboard dead?

probably not but your RAM might be

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

What should I do to test if it is or not?

Oh god, RAM is not hot-swappable!

 

Yes, the RAM may probably have fried itself when you took it out. If you can borrow another stick, see if that's the problem.

 

Unfortunately the ram sockets might also have been damaged which would spell doom for your motherboard.

We have a NEW and GLORIOUSER-ER-ER PSU Tier List Now. (dammit @LukeSavenije stop coming up with new ones)

Turn it off, put ram in, turn it on. Works, good. Doesn't, fucked.

Well, the obvious is to test different RAM sticks, do you have an old PC lying around?

lmao.. you may have killed something.

Simply use only one stick of RAM at a time. By doing that you can see if one of the RAM sticks is dead.
You can also try each RAM stick in a different slot on your motherboard, to make sure all RAM-slots are working correctly.

I am not exactly sure how how you can "accidentally" take the RAM out as you need to push down on 2 thingies to unclip the RAM. But anyway, try taking it to your nearest PC repair shop. They will try to put some of their RAM in and then you can see if it is the RAM or the motherboard. I think that it might be the RAM though.

He obviously didn't take the RAM out by accident. That's like getting in your car and driving around the world, by accident. He obviously took it out without realising it would damage.

Yeah.. It is a bit odd. But everyone does stupid things!

No, the PC was turned off, but my PSU was turned on and powered to the wall.

Just hope that it isn't dead then. try putting different ram in. If it doesn't turn on, It is either you fried the motherboard or something else is causing the problem.

If your PSU was on, then how was nothing else on? Did you unplug everything with the PSU on?

ATX machines never really do power down fully unless you physically remove all power or its one of the PSU's with a switch for the purpose. 

 

That's why many vendors include a LED on the motherboard, which remains lit even when the computer is "turned off" through the ATX soft-power switch.

Ahh.. I see.. But he should have at least unplugged the cable to the PSU when opening his PC then. It what if he had static electricity on him and he transferred  it to a hardware and caused a short circuit? It happens. And also one of the components could have shocked him. And, he could damage hardware (which is what happened in this case).

Yeah he could have damaged hardware.  Its very poor practice to be working on a live machine like that with such critical components like the main system RAM.  But I've had a few "accidents" myself over the years and have never wrecked anything that way after a good and proper reset.

Maybe clearing CMOS and unplugging / replugging will do the trick. I thought OP had replaced the RAM while the computer was on.

Okay, my motherboard is working, and now it's giving me five beeps.

Tried re-putting the CPU, RAM on the first slots that the MOBO indicates, still not working.

What should I do?

Your having a RAM issue. You need to get new RAM.

Great! Don't touch the PC until the computer is fully unplugged! ;)
