Man, I had EXACTLY THE SAME symptoms that you had. This was the only vid I found in whole YouTube (trust me, I've searched) that helped me. My 5V was 4.7, today I dismounted all my components, cleaned the power suply connections with isopropyl alcohol, and then turned all back on, and... VOILÀ! My PC is back. I Thank you much, i've liked and subscribed. Thank you a lot <3

Cable extensions removed and the problem disappeared. You are the MVP!

[ehdriel]

damn this might be on of the best how to fix videos ive ever seen on youtube. really well spoken and straight to the point. thank you

Thank you, this video helped me. I was having random blue screen when playing steam games for like 5 months now. I thought it's just my ram or something. But after watching your video, I removed the 2 extension cable that I bought from amazon that is connected to my GPU then used the cable from PSU straight to my GPU. It works no more blue screen. I think it's really because of the extension cable.

Had this issue everytime I load CSGO or Forza Horizon 5, straight away BSOD, took out my cable extensions, fixed the problem, tyvm!

I had the same issue, even while playing Nikke on my PC, so after i watched your video, i bought a new power supply today. I can now play all my games without any issues, including The First Descendant on Ultra settings. Thank you very much

Terrific video Charlie. Very thorough and methodical. I had some USB instability in the past but never considered it to be caused by the power supply. I upgraded to another PSU about a year ago to allow for a GPU upgrade and now that I think about those intermittent USB issues also went away. For some reason I never put 2 and 2 together there. So perhaps I had the same issue as you. I will have to test the old PSU now as I was keeping it around as a spare but if the voltage levels have diminished then maybe it should be disposed of instead.

Amazing work as always 🤗 And amazing to see how you figured out the issue step by step, not everyone will think abt the power supply but more likely think it's the motherboard 👏👏👏

I’ve had this problem for nearly 2 months now. I built a whole new pc, and I was shocked because I thought I might’ve installed the wrong drivers etc. I replaced the MB for a better one and I got a better GPU than the one I had. Still ran into the issue, but I did notice how the mouse would just DISAPPEAR Sometimes, or stop working. I will be diagnosing the PSU later. Hopefully this is what it is. Thank you!!!

Been dealing with WHEA_Uncorrectable error for weeks.

Turns out all I needed was a trip to best buy for a new PSU. Thanks Charlie!

[PaleoReal]

I cant thank you enough, for helping troubleshoot. You helped me solve my problem for the past few months and it was getting worse.

[L-Vanquisher]

i have the same issue.
Hardware:-
CPU Ryzen 5900x
Mother Board - Asus ROG B550 Gaming WIFI II
RAM - ADATA 32 GB 3200 Mhz
PSU - Corsair RM850
GPU -MSI 1070 GTX 8 GB

I have checked all the voltage in HWMONITER it's fine but facing this issue while playing games.

Please help.

[triciae]

Mine happens randomly…when I’m idle, just looking at social media, etc. any suggestions?

[landon]

I’ve been having that issue and got a new power supply and everything but it just started happening again. After replacing the motherboard the pc crashing stopped for a week or two and then just started doing it again

[MrBess]

if CSM legacy mode is enabled then is possible that you have same issue like i had..so i disabled CSM in BIOS uefi..and since then works fine to me.

[GermanXBL]

My new PSU is coming today, and i hope so much my Bluescreens and shutdowns, freezes are because of my old PSU, i bought a few days ago a new M2 SSD bc i thought its coming from there but no, I'm pretty confident because of you that its my PSU, i will see it later :D Thanks in advance <3

For me it was those super pretty psu extension cables, removed them and haven't had an issue since!

[PatrykPL]

WHEA errors are due to low voltage - correct. In your case it was PSU. However in most cases it is a sign of a defective CPU. Usually on low loads while the CPU boost to a very high clocks it "demands" too little voltage from your motherboard that is not enough to sustain itself and so it throws cache error and crashes. Pretty common with 5000 series CPUs unfortunately... RMA is your only solution for a permanent fix. Of course as long as your new CPU also isn't defective..

Very helpful video. Thank you so much for creating this. 👍👍

[gustavonasserd]

I loved u vídeo. Ive been facing LITERALLY THE SAME ISSUE. Hoping to my new PSU fix the problem! I ordered a new one.
