Can drawing too much current from an outlet damage a motherboard?

I had two mobos fried over the course of two days, first one went bad overnight. I left my computer on, woke up and it was off, tried to turn it on but nothing. Unplugged everything, cleaned it, tried again and fans spinned for half a second but no lights and every attempt after was the same.


Put in a spare mobo and everything worked fine for a day, woke up next morning and pc booted right up, went somewhere came back and it was off, tried to turn it on but nothing.

I'm no expert but since the pc worked fine for a day after I installed spare mobo, this should lower the possibility of the psu, gpu, cpu, or any components as the cause. Which leads me to the next possibility... a power surge or possibly a lack of power being supplied to the computer.

I currently have two surge protected 6 outlet cords plugged into a common household outlet. That single outlet supplies power to my PC, a 32" monitor, amcrest surveillance cam, fan, heater, DVR, 19" monitor, wifi modem, modem backup battery, chargers for my phone/tablet/other devices, and desk lamp; sometimes I plug in other electronics into the spare outlets also.

Now that I look back on it, I recall how my desk light would flicker when booting up my computer at night, and how my heater would randomly shut off, and how my phone wouldn't charge or charge really slow, and I'm almost positive that it's due to a lack of power due to having too many things plugged in.

Did I hit the nail on the coffin here? A knowledgeable opinion would be much appreciated.

The heater being on that circuit with everything else I'm surprised your breaker hasn't flipped. You need to separate that load.

Is the outlet safe to use or should I move everything to another outlet on the other side of my room?

You'll be fine if you remove some of the load from that individual circuit, which could actually be the entire room.

Went out n bought this UPS

This should protect my pc from any electrical issues right? And what are the odds that it isn't the outlet but a computer component that's causing the mobos to fail?

I'm only replacing the mobo and PSU but I'm a bit worried that maybe... just maybe it was the CPU, ram, or hard drive.

Add one component at a time and see what happens.

An ups is just a battery. Although, a battery could in theory help stabilize a current.

You still need to separate some of that load.

Sorry for the late reply. So today I installed my new mobo and PSU, computer booted up to bios, then after several seconds the display went out but computer stayed running. Forced a shutdown, turned it back on and same thing. Tried a third time and it booted up but no display and the power LED was dim, then it shut down shortly after. This is after I replaced old outlet with a GFCI one, unplugged everything except for UPS, computer, monitor and modem.

Now what I don't fully understand is I had my old rig hooked up while waiting for replacement parts to arrive and same thing happened (randomly shutdown and wouldn't turn back on), but when I unplugged it and tried again on another outlet it booted up fine. At this point I'm almost sure that particular outlet is the culprit.

Tried the same thing with my main rig after i already installed new parts and failed to get it working the first time... but it still didn't work.

My old rig which I built in 2010 was able to start up after I thought it was toasted but my new rig won't? I'm nearing the end if my wits here... tossing this computer off the roof a skyscraper is starting to sound like a good idea.
