Hello. First time posting. I have worked IT for 2 plus years and seen and fixed a lot of problems, but my personal rig has me stumped with a new one. I have a triple monitor set up with a ryzen 5800X3D, 1000W Seasonic 80+ gold PSU, and a Radeon Vega 64 GPU. (I think those are all the necessary related specs. If you want more I give further detail.) And ever since I swapped my cpu which is being cooled by a triple radiator AIO that is making proper contact, I am randomly having my computer black screen and displays showing no connection found to me. The rest of the PC is working fine. I can use my keyboard to shut it down. I even was in game once and could here and talk to my teammate but couldn't see anything. (I'm am not always able to do that but have been able to a couple of time.) I'm inclined to think it is GPU related but it is so inconsistent that I don't think that it is related to the GPU dying. I am on a Crosshair VI that I had to update the bios on to get the 5809X3D to run. (Was running an 1800X foe the past 5+ years). I am hoping that it is something software related as I don't have a GPU upgrade in my budget till about Christmas time. The frequency is anywhere from 2x a day to 1 every couple of days. It has happened under load it has happened idling on the windows home screen. I just can't pin point the problem and why it is happening. Feel free to ask any questions and I will do my best to answer to the best of my ability. Thanks in advance for any help.
So I have had my PC for an extended period of time, and within the past 2 or so years I finally added 2 more sticks of RAM to fill out my 4 slots. My PC reads these sticks with no problem as they are all the exact same RAM, but I have recently noticed weird behavior when I start really uping my usage of RAM. I have four 8GB sticks and I notice consistently that when I hit that 16Gb usage instead of bumping up to 17 Gb it holds at that 16 Gb mark and everything starts to lag. Is it because PCs are optimized for 2 stick configuration? Is there a way to change that in the BIOS? I am just generally confused by the behavior. Thx in advance for the assistance!
