Question Video not displaying after installing different ram

[Novacore676]

Allllright, so brace yourself because the journey leading up to the issue i have currently is a long one and needs to be explained, but first, let me share the system specifications for the computer i am having an issue with right now:
-Ryzen 5 5600x (no integrated gpu)
-evga gtx 1080ti graphics card
-corsair 3600 vengeance non rgb 2x8gb in dual channel
-corsair 1000w psu rm1000x (got it in case the new cards will need more power)
-mpg b550 gaming plus motherboard
-samsung 1tb m.2 nvme ssd (970 i think?) also another 1tb crucial m.2

That is the computer i currently am having an issue with ^

There is another computer that has a slight role in this which is my main computer. Here are the specs:
-9900k processor
-founders rtx 3090
-corsair vengeance rgb 3200 ram (2x16gb)
-corsair rm850w psu
-asus maximus hero motherboard (id have to go look at the exact one since i am at work)
-2 samsung 1tb nvme m.2 ssds

This computer is fine but it plays a part in the story and here is the explanation.

Initally, the ryzen build computer stopped sending video out of nowhere. I did some troubleshooting and some of this troubleshooting lead me to take the 1080ti graphics card out of the ryzen build and place it in the 9900k build that housed the 3090. So i swapped those cards and i probably should have reset the drivers first but the computer was not working correctly with the 1080ti in it HOWEVER, the monitors were responding as if there was video, so i know the graphics card was sending some kind of video signal.

So i took the 1080ti out of it and put in the 3090.... well i ended up having similar issues now on that 9900k build. eventually i was able to fix that issue HOWEVER, my computer started having blue screen errors on the 9900k build. things to do with IRQL_NOT_LESS_THAN_EQUAL and other system error bluescreens. So the computer would crash randomly, especially when i would load some games. But i just dealt with that crash for a while and went back to the ryzen build to figure that mess out.

So back to the ryzen build, i reinstalled the graphics card and i was still not getting any response from multiple monitors, multiple cords, displayport, hdmi, dvi, etc. nothing worked. So i took out the power supply which was an older 650w seasonic psu and replaced it with a corsair rm1000x psu and SOMEHOW this fixed my issue. i actually took the time to take out the corsair powersupply again and put the seasonic psu in again to see if it would work.... it did not, so i guess that issue was the PSU.

So problem solved for now for the ryzen build. Computer worked for weeks, no issues, nothing.

Now back to the 9900k build. This computer was crashing and i put up with it for a bit cuz it wasnt that frequent or at important times and the computer would load fast so sure, w/e. i will wait to deal with it. So the other day i decided to deal with it. What i did was take some of my ram out of the ryzen build and put it in the 9900k build. Well magically, the past 2 days my 9900k is not crashing anymore. Perfect, so maybe its a ram driver issue or maybe somehow installing that gtx 1080ti into the 9900k caused the ram to have some sort of defect? IDK. SO i wanted to test the ram naturally.

So being the dummy i am, i took the ram that was in my 9900k build that was crashing and put it into the ryzen 5 build that seemed to be running smoothly again. I turned off the computer, turned off the switch on the PSU and installed the 3200mhz rgb vengeance ram into the ryzen 5 build. SOOOO now im getting a similar issue as before where the monitor is saying no signal but my computer is running, lights on for everything. i feel like its posting to the login screen because i have to hold the power button a while to turn it off, usually if it was in the bios, it would just turn off instantly after hitting the power button? (correct me if im wrong).

So i try putting the ram that was working back into the ryzen build and its the same issue. No video is displaying. I am hoping the PSU isn't messed up again cuz it was an expensive one for sure. i guess ill buy another one or see if i can get it replaced from corsair if that is the issue, but if anyone has any insight on this issue before i do any of that, please let me know.

I have tried taking out the cmos battery and waiting quite a while to put it back in and that didnt change anything, but maybe i am doing this wrong. I know some things about PC's like putting them together and some minor technical things but i wouldn't call myself a master, or hardly even an expert. just a nerd that likes building pc's and troubleshooting.

Thank you for reading this and all input is welcome.

EDIT: I removed cmos battery again, took a screwdriver to the jbat1 pins for 10 seconds. plugged the power back in, reset the computer, still no video. Tried different cords and a different monitor. Still no video. Different ports on the graphics. Nothing.

I spammed delete on the keyboard while it booted to see if it would go into bios and I checked this by turning off the computer after I believed it was in the bios. The computer turned off as soon as I pushed the power button, so I know it entered bios even though I cannot see anything. If I don't enter bios, I have to hold the button a while to turn it off, which tells me this computer can boot to bios and also can boot to the login windows screen based on the delay when turning off or lack thereof.

Problem solved: So as i said with the response to RealBeast, after resetting the bios with the cmos battery/pins, different monitors, different cables, different connections, nothing solved the issue, so i gave up for several hours. Then decided to just turn it on again and see if anything changed, it worked out of nowhere. Not sure what the fix was. But its working fine for the ryzen build.

I would like to add one more thing and it is pertaining to my 9900k/3090 build. Like i said before, it was crashing with multiple error codes that gave me the feeling that it had something to do with the ram at minimum. whether it was the hardware or drivers. drivers were up to date, reseated them, nothing worked. I instead went into the bios and did 2 things. 1. i messed with the xmp profile by turning it off and back on again to get the correct mhz. 2. i have an asus motherboard and i never noticed the AI overclock feature and decided to just give it a try. I used to manually overclock things a long time ago but it never really made sense for me to do so anymore since it is more than fast enough as is. Well i turned that on as well as the xmp profile, and 3 days have gone by with no crashing at all. Fingers crossed that this is permanently fixed because it would crash 2-3 times a day.

Test the problem memory with MEMTEST86 free version that will boot up from a USB into a Linux boot that actually just tests the memory at the settings indicated. Swapping to another computer is not really a valid method to test memory, assuming it is even compatible memory.

If you don't get at least 3 complete passes with zero errors at the memory set specs, RMA it for a new set.

edit: also, with some newer boards just removing the bios battery won't necessarily reset the bios, you need to short the pins on the motherboard for reset.

Thank you for the reponse.

I honestly should have just did a memory test but I didn't throw the ram back into the 9900k build since it was running smoothly so I figured it would be fine putting it in the other computer but obviously not.

I was wondering that too with the cmos battery. I see the pins underneath the cmos battery but I do not have the housing to put into those pins. Am I able to use something like two screwdrivers on the pins to make contact with it?

Thank you.

You can either use any two pin jumper, make a prolonged contact with something metal like a small screwdriver (with the computer off in either case), or in some newer and all older boards remove the cmos battery with the PSU either unplugged or the power switch on it to off position.

I tried this and it still is not working. No video.

Used a screwdriver in the two pin jbat1 under the cmos battery with the computer turned off and unplugged for 10+ seconds.

Still no video showing on the screen. computer boots up but nothing is dhown.

Does it show video when you boot from the Memtest USB stick?

Hello again and sorry for the delayed response.

Before i attempted that, i just waited a bit. Continuously trying to turn it on to see if anything changes. Nothing changed for a while. waited a bit more, probably about 6 hours and tried again randomly and it just came back on.

I am not sure what really changed, not sure anything has changed honestly. I tried multiple times taking out the cmos battery and also resetting the bios with a screwdriver on the pins. Tried different monitors, different cords. I gave up for a while and then just tried it again randomly and it booted up. So the ryzen build has been working for the last couple of days with no issues.
