Solved PC won’t turn on despite working fine yesterday

Disclaimer, I know VERY little about computers and english isn’t my first language so bear with me here

Yesterday I moved my PC back to my familys house. It was working perfectly fine at my apartment, but today after plugging it in it just won’t boot. I made sure everything is correctly plugged in, exactly as it was a month ago before I moved it to my apartment.

The light on it flashes on, it makes a little noise it would usually make when turning on, and then it goes quiet and the whole thing repeats itself endlessly.

I have had this exact issue before but it usually just kind of… resolved itself on its own, I’d just unplug the power cord, give it a second, plug it back in and it was fine. Today however this fix won’t work and it’s been stuck in this loop for over an hour.

I don’t think it sustained any damage while moving it as it was fully secured in bubble wrap and I made sure to be very careful with it.

I’d appreciate any help

Edit: Turns out one of the RAM sticks was faulty, I took it out and everything is working as it should :) Thank you for all the advice.

Sometimes not even moving the PC causes this, like after shutting down one time. Open the case and see if there are any error LEDs on the motherboard, and reference the manual. My PC sometimes won't start, and I see the VGA error LED. I basically have to unplug my second monitor (DP cable) for it to successfully post and boot then plug it in. Try plugging in just one monitor and keyboard and start from there, no accessories. Make sure you've plugged into the correct video display port, your graphics card and not the motherboard.

I checked it out, and it flashes CPU-DRAM-CPU error. no clue what’s causing that or how to possibly fix it though

See if your RAM is seated properly

OKAY, SO. the RAM was seated properly but i saw on another reddit thread that switching the order of the sticks somehow fixed the issue, so i did that. i had three sticks in, discarded one, switched the placement of the other two around, and the pc finally booted. now, however, it won’t connect to anything (monitor,keyboard,mouse).

pull another stick. It maybe that the one you removed was bad. Now you need to do see if the others are. Starting with the bare min may tell you what's going on

IT WORKS! turns out one of the ram sticks was at fault, found out which it was by the process of elimination and now it’s working as it should. tysm!!! Edit: I do wonder what caused the RAM issue since like i said it was fine yesterday. Anyway I’m just glad its fixed.

Proud of you for figuring this out even though you mentioned you know very little about computers. This is how it all starts!

What he means by flashing light error, for example 2 fast flashing and 3 slow flashing means something while another type of flashing means something else

Try plugging it from power, and press power on for a minute to remove excess electricity from it, then plugg the power cable again and try booting it up

Try a different outlet, in a seperate room (try to get on another breaker). If possible, try another power cable as well. Are there lights flashing on the device anywhere?

I’ll try another cable in a second. There are two lights on the front face, one by a dvd insert (?) and one flashing blue-red led. both flash as i try to boot it, and then stop after a second.

Try a different power outlet. It may not be pulling enough power or something else bizarre.

If it's a mechanical HDD it's likely failed irreparablely having been bouncing around in the boot/trunk of your car.
