Question I’m at a loss.

[B4nd4idb0yz]

I apologize in advance for any lack of knowledge about computers I have, also for the length this post is about it be.
I bought a prebuilt pc a few years ago, (first gaming pc) she has served me well. Monster hunter wilds came out and I figured, hey putting a new cpu in and updating the bios will be a piece of cake. Welp, I broke the number one rule, I messed with it while the bios were updating (while the computer was restarting). I watched every YouTube video, looked up a million things on google and even posted on Reddit, I got a few good suggestions, tried flashing the bios with this chip thingy I forget what it’s called. Nothing worked. So I caved and bought a new motherboard and figured all my problems were solved.. nope. I installed the motherboard and the new cpu plugged everything in annddddd the leds and fans turn on but I’m still getting no display, no bios. No boot up screen, nothing. I’m at a loss, I know I should just take it to a computer repair place but this was supposed to be a simple and cheap maneuver in the first place, computer building is far from my hobby. I just like playing games. I know I never should’ve messed with it !! I’m starting to think the issue might be two dead ram sticks..(somehow) or a bunk ssd. I’d really just like a straight answer so i know what to buy but I figure I won’t get that unless I hand my computer over to a professional. Really hoping it isnt the ssd I’m not sure how this all works but I’d really like to not lose anything. I didn’t have any issues until trying to replace the cpu and updating the bios, I never opened the new cpu until installing the new motherboard. Reddit told me to just get a new motherboard. So I did. Not sure why it won’t give me any screen. The monitor won’t detect any signal from the computer. I have a gigabyte A520M S2H motherboard
AMD RYZEN 5
Redline frostbyte RAM
Mushkin helix 500gb ssd
500w aresgame power supply??
I’ve checked the cables a million times. I just bought a new flash drive to try and maybe update the bios on the new motherboard or reinstall windows??
Maybe a bad power supply?
Any help is appreciated! Thank you. (Ik this is very silly)

Well it's not uncommon for a new build to not work at first, and it really helps to have a pile of parts to swap around.

You swap the parts you have first, so try the old CPU in each board with only 1 RAM stick. Note that Ryzen 5 for AM4 doesn't have an IGP unless it's an APU (like 2400G, 3400G, 4600G or 5700G), so if you switched from an APU to a regular Ryzen, the motherboard video outputs are supposed to be dead as a discrete GPU is required with those. That board also doesn't have an onboard speaker so you have to plug one in to hear any beeps.

If you can solder 8 leads, replacement preprogrammed BIOS chips are only $15 shipped, and someone does have a whole board for parts for about the same price. If you solder a clamshell SOP8 socket to a working board, you could boot from a good BIOS chip and hot-swap it for a bad one then flash that the normal way... but the socket costs nearly as much as a BIOS chip.

Hi I have had this happen many times with building new PC's. Fans running full speed led lights on and no video. What worked for me was to shut down everything disconnect the power discharge the motherboard by pressing the case power button for about 5 seconds then remove the CMOS battery for about 15 mins. This resets the motherboard to default settings. Replace the CMOS battery re - seat all of the hardware GPU RAM and Drive cables all power cables from the PSU and motherboard. You should have your CPU installed correctly with sufficient thermal paste with an adequate cooler installed. Check your HDMI cables that they are securely installed on the PC and your monitor with the correct video input set on the monitor from the PC. To begin with you can install 1 stick of RAM. Install a Beep speaker then start the PC and see if it will give any beep codes If there are error beep codes please post them here . People here can help you with this. If it gives a single beep that is the POST beep it should now show the BIOS splashscreen. Hit the Delete key or F1 or the key specific to your motherboard BIOS to enter the BIOS. If you have a BIOS screen the settings will be at default at this time. You can tweak the board later for gaming and install the rest of the RAM, save the current settings and reboot then wait for the motherboard to train the RAM. It will turn on and off a few times before it will boot into Windows. If you still have no joy please kindly list the issues here again. There are people here who can help you resolve the issues and help you get your PC up and running again. My post is just a suggestion that I hope will help. Cheers from an old school PC builder and Gamer.

Any help is appreciated!

List full specs of your system.

old motherboard, new motherboard (gigabyte A520M S2H - is that the new one?),​

old cpu, new cpu (AMD RYZEN 5 says nothing, there are more than 50 models),​

graphics card (do you even have any?).​

Thank you SkyNetRising They should list their Hardware so people here can help them resolve their issues.

Need detailed specs. Other than double checking that ALL components have been seated properly, we need to make sure your new motherboard is compatible with your old hardware. Just because its a new board doesn't necessarily mean it can work with your new CPU. Sometimes the bios on a new board needs flashed before it can work with its full range of "supported" hardware. This includes the ram. What size sticks? What speed? What voltage? Lookup your board on gigabyte's site for the ram compatibility list. Do you get any series of beeps when you turn it on?

Can you get into the bios on the new board? What version is the firmware?

Simply put, it sounds like either something isn't fulling seated properly or you have a compatibility issue. If you can't even POST, see if you can use the old CPU. Also, try 1 ram stick at a time. Did you plug in all necessary power cables to the motherboard?

Umm, there's no GPU listed at any point. Could the initial CPU have been an APU and the new one not?

We *really* need to know the full specs, both old and new, to be able to provide help that isn't of the vaguest variety.
