Pc turns off randomly but rgb is still on.

[APGGP]

I recently decided to get a new case and an extra fan for my pc. It booted up one the first time and everything seemed to going correctly. After 20 minutes of being on windows watching YouTube, I lost signal to my monitor and I seen that the rgb was still on and the fans were still going. It gave me no bsod. I have speakers connected to the pc as well so it made a pop noise. It makes that noise when I turn off the pc normally. The pc didn’t restart or turn off completely. The monitor was on a black screen saying no signal. I should also mention that before I switched the case, the pc ran completely fine with 0 issues. I was looking up reasons on why this could happen and everyone was saying it’s probably a psu issue. I decided to buy a new one and it’s still doing it. Both psu’s I have are 1000w which is probably overkill. I stress test the gpu and cpu to see if maybe that’s the reason and it didn’t turn off. I did memtest and both my sticks passed. Only thing I can think of is the mobo but I’m not sure why that would just stop working after only changing the case and adding a fan. When I check event viewer it just says kernel 41 or something like that. Sometimes it’ll happen after 5 minutes, 20 minutes, 3 hours or never. If I don’t shut the pc off before going to bed, it won’t happen again. It also only happens when going into windows. It won’t happen if I let it sit in the login screen or go into bios. Not sure if that matters. Temps under load are normal. CPU at most hits 81 on warzone and GPU hits maybe 60.

Select the event, click on the Details tab (Right above where it gives you information about the event) and screenshot.

Unless you have a WHEA-logger event in the 10 minutes before/after the Kernel-Power event, this looks like it just lost power. So a power issue would be the main suspect. Be that the PSU, the power cable, a bad power strip or unstable power from the wall. 

 

If you do have a WHEA-logger event, right click → save it and upload it to the forum.

I already changed my power supply though. The only thing I can think of is that the case is weird. The psu is mounted vertically but basically the case has its own power cable inside that you plug into the psu. The back of the case is where the plug from the wall gets plugged into. Although I’ve already tried plugging the power cable from the wall directly to the psu.
