acer nitro n50-600 Blue Screen of Death - I think ive tried everything. Any advice is welcome :)

Hi acer community. The infamous BSOD has been plagueing my Acer Nitro n50-600 for 3 days now without any signs of improvement. The PC is only 4 years old, it has truly saddened me.

I read about possible fixes and tried so many things, many of which the computer does not allow as the BSOD appears sometimes very quickly. Yes its incredibly frustrating. Im already thinking about just throwing it in the garbage and buying a new pc, but im writing on this community for the first time to see if others have some suggestions! :) (Other than the things ive already tried ofcourse).

Some more info about the BSOD: the source codes are:

• system service exception
• registry error
• memory management

the system service exception source code seems to appear most often.

Weird thing is also, when it restarts it always losses anything i removed or installed previously. Any app,program, driver or file that was modified by me (in attempt to fix it) seem to be reverted upon restarting. upon restart the pc and all of its features/settings goes back to its previous state. Anything that you remove, will appear again when it crashes from restart or from manual restart.

Furthermore, the WinRe environment seems to be enabled, but it simply will not enter the WinRe. Not from any method. Not from advanced startup, f9 or f12 hold, not from power off 3-5x when manufacturer is displayed, and not from shift-power combination. Also tried to safe boot with settings, minimal> hide microsoft programs and then disable all startapps.

Other information of what ive tried:

cmd scans: often cannot finish without BSOD

• driver updates or rollback on gpu drivers. installing a new nvidia driver from website.
• sfc /scannow: will come up with corrupt files and them being repaired. but still no fix
• DISM scans, checkhealth, scanhealth, restore health. BSOD will appear before scans can be finished.
• disc checker via command chkdsk C: /f or /r: cannot lock current drive is a message i get. If i want this to be checked upon restart (by pressing Y), then it simply does not do it upon restarting.
• Disc clean up for both C and D drives.
• memory diagnostic tool. the pc restarts without checking memory. also does nothing.
• virus: quick scan finishes, does not find threats. Full scan cannot finish before BSOD.
• malwarebytes + windows malicious tool : no threats detected.
• CCleaner: registry cleaner until no issues are found
• Windows update: comes with error and it cannot download. (download error 0x800b0003). tried refreshing win.updater with multiple cmd functions that i found online). Also tried the troubleshooter here.
• Reset this pc: either wont finish setting up, or during setup goes immediately to 100% and restarts without any changes.
• cleaning temp filders and folders.
• Tried fortect app, but this will not open at all after installation.
• uninstall recent apps/programs. i did not install anything recently, or on the day the BSOD started. but i tried to make sure. upon restarting however, those apps return somehow.
• DDU, display driver unistaller, used the clean and restart option.
• Remove pheripherals - change keyboard/mouse, change monitor.
• Change power source: simply using electricity socket in diff. room.
• Restore points, cannot complete reverting to 1-day prior to BSOD point.
• Uninstall previous windows updates.
• component wise, took apart the pc and all its hardware. checked if things were correctly plugged in.
• un-dusted the insides and sockets.
• reseated the RAM multiple times.
• reseated GPU and CPU.

None of the above has resolved the blue screen of death. I've been trying for 3 days now.

If yall have any suggestions i welcome them! I am really lost about this.

Im thinking either hardware that has broken or a undetectable virus/malware.

Thank you for your help in the future:) And if you need more info let me know
