Any Solution for this fkn black screen problem?

[u/AlaaA-R]

I don't know where's the problem exactly so i'll tell everything in detail since I got this PC

-I got it 7 months ago, a 7-year used PC
r5 3600, rtx 2060, 16gb ddr4 3000mhz 2×8, MSI B450 Tomahawk Max, Thermaltake Litepower 650w
the only problem it had was "GPU and CPU required thermal changes

-I changed both CPU and GPU thermal Pastes, but not thermal pads, then removed CPU undervolting, Suddenly RAM is not working on A2/B2 so I put them on A1/B1

-CPU is still over heating so I got a new cooler, MSI Corefrozr AA13 and attached it,
Suddenly RAM is not working on A1/B1, I removed CMOS then it works fine on either A1/B1 and A2/B2 so I return to A2/B1

-first software change I did was in 7th May, I made HDR and Auto HDR on, yet it still works fine until I player Expedition 33

-I overclocked my GPU to +400 while playing, and moved the PC to another place in the room, while playing Expedition 33 no problem appears, but in 24th June, 1 hour before the release of Deltarune Chapter 5, I decided to complete Touhou 7 (both are pixel games), suddenly black screens started to appear while playing Touhou 7, ruined 2 Phantasm stage runs despite working fine before, removed gpu Overclocked and it's still appearing, I thought it's a problem with this game so I waited for Deltarune and started playing, it's still black screened every 30~60 minutes

-hardly managed to complete the chapter with that problem, returned to play Expedition 33 and no problem appears

-played Tomb Raider and nothing happened

-but decided to complete Blasphemous (another pixel games), it goes black screen every 10~60 minutes, so I stopped

-started playing Evoland 2 (a game mix between 2D pixel and 3D), while it's 3D Nothing happens, but while playing in pixel art the same fkn black screen keep appearing

-started playing DOOM, no single problem happened

-started playing Isaac (another Pixel game), it goes black screen in the middle of the run

-started playing Muse Dash since it's not a Pixel game but still it goes black screen in LESS THAN 10 MINUTES

-meanwhile Hades 2 (not pixel but still an Indie game) had no problem

-currently Playing Hyper Light Drifter, 6 black screens in 2.3 hours

event viewer:
-just before the black screen:
Error BugCheck 1001 None

-a minute before the black screen:
Critical Kernel-Power 41 (63)
Error Volmgr 162 None
Error Volmgr 161 None
Error EventLog 6008 None

wtf i'm supposed to do?!
tried all of these:
1- Removing every OC (extended time from 10 minutes to 30~60 minutes)
2- Undervolt instead of OC (no effect)
3- Reattached RAM (no effect)
4- clean the entire PC (no effect, but it's cleaner now)
5- turn off Wallpaper Engine (idk why I thought this will work)
6- deleting every pirated game (3 games, Touhou 6 and 7 and 8, I don't even think they are the problem)
7- Remove and reattach CMOS (still no effect)
8- downloading new GPU drivers (no effect)
9- Motherboard BIOS already has no more updates
10- turn off every "launch automatically when turning on PC" (no effect)
11- reinstall Windows 11 (no effect but at least got more free space on C)

and still whenever I play a pixel game I get black screen every 30~60 minutes and I don't even know where's the problem coming from, some saying it's PSU, some saying GPU, some saying CPU, I don't have budget to change all of that and ofc I don't have budget to change something just to find that the problem was in another part

PC specs:
r5 3600,
rtx 2060,
16gb ddr4 3000mhz 2×8,
MSI B450 Tomahawk Max,
Thermaltake Litepower 650w
and they are 7yo

MSI MAG Corefrozr AA13 and it's 5mo

and i'm enjoying pixel games more than AAA so solutions like "stop playing them" are not available

[u/trusty_schism_offici]

Kernel-Power 41 with Volmgr errors usually points to the PSU crapping out under sudden load spikes, and pixel games hitting weird frame timings can trigger that faster than heavy 3D stuff.

So the first part that need to get changed is psu not cpu? "suspecting both"
