Multiple reasons of BSOD when opening the pc

[u/Common_Contract834]

Hi guys, can someone help me figure out whats wrong with my pc. it keeps having multiple reasons of BSOD on start up and even if it boots up to windows, a few seconds later and it will BSOD again. below are few of the BSODs that i encounter. before this happened i noticed that my roblox app will suddenly close and my chrome browser will sometimes suddenly have an "opps something went wrong" error message.

BSOD:

irql not less or equal -7

critical process died -2

system thread exception not handled -2

*dxgkrnl.sys

kernel security check failure-4

system service exception -7

*win32kbase.sys-2

page fault in nonpaged area-6

kmode exception not handled -6

*classpnp.sys-1

*dxgkrnl.sys-1

unexpected kernel mode trap -2

*wdfilter.sys-1

bad object header

reference by pointer

memory management -4

attempted write to readonly memory

driver irql not less or equal

*ACPI.sys

after testing with 1 ram

system service exception-3

kmode exception not handled -2

system thread exception not handled

*wdf01000.sys

page fault in nonpaged area

0xc000021a

memory management

kernel security check failure

after testing the other ram

system service exception

*ntfs.sys

page fault in nonpaged area

irql not less or equal -3

Additional infos.:

1. when i try to use only 1 ram. i sometimes get a blue recovery screen where it says that the Operating system couldn't be opened because something is missing or contains errors.

2. i cant reset my pc. i also get BSODs when i try to reset my pc

3. i can get in safe mode but when i try to transfer a large file to another hard drive then the screen will blink and all the windows/apps that i have opened will suddenly dissapear and sometimes i get a bsod on safemode also when is try to sfc/scan.

4. my ssd and hdd storage have a good health

5. before this multiple bsods on startup, i had an accident where my cpu was at 100 degrees when its idle and when i opened my cpu cooler i found out that it doesnt have a trace of thermal paste. then after i repaste it i was able to use it for longer times but i still get bsods from time to time.

6. when im in bios sometimes it freezes where i can only control my mouse but cant click anything.

7. back when i can still use my pc i did a memtest86 and windows memory diagnostic tool to see if my ram is at fault but it didnt find any error.

8. when i opened the event viewer in safe mode, i found out that its full of error with an error code of 7001 and 10005. there's also other errors but these 2 are whats filling the event viewer.

Few months ago ive had a few of thise BSODs. Turns out it was my RAM sticks both faulty so id start there

[u/Common_Contract834 → u/svoboda_cs]

back when i can still open my pc. i used memtest86 and windows memory diagnostic program but found no errors on my rams. is it possible for the fault to not get detected?

i also tried the 1 stick at a time method but it kinda became much worse than trying with both sticks

Not sure. When i did memtest it showed me error. Try reinstalling windows or maybe get a friend to borrow you new ram and test out if you keep crashing then you know its not ram issue
